Running gear
Whilst I am
starting on the running gear, I do still have some remaining tasks to do to the
underside. I have bought some Gravitex underseal which I need to apply, but prior to that
I have been giving the inside floor a once over. I’ve found a few pinholes which I’ve welded
up, and it would have ruined the underseal had I done that already, so it was
wise to wait until everything else has been completed first. I’ve also given
the floor a coat of paint, well, half of it has had a coat of paint, I’ll do the other half on the weekend.
I managed to
find the rear axle and front subframe under the pile of parts I’ve removed more
recently, and wheeled them outside for a quick power-wash. They came up quite well, but the object of
the exercise was purely to remove the crud prior to striping them down rather
than to make them ready to refit. I intend to replace all of the seals,
gaskets, bearings and bushes with new, also all four hubs need to be replaced
to accommodate the chrome wire wheels.
They need a splined hub instead of the current five stud versions. The front hubs are relatively straight
forward to swap, but the rear hubs are infamously difficult to remove. Regular hub pullers will break and a
specialist tool is required. Even then,
many people ‘mushroom’ the end of the shaft with the pressure being applied, so
caution is required as the shafts are not easily sourced. The problem is that the taper fit is a very
shallow one, and takes an enormous effort to overcome the friction fit.
The front
coil springs are also difficult to remove as the subframe design does not leave
enough room around the springs to fit regular ‘coil spring clamps’, so a
different technique is required. This
involves removing each of the lower spring plate bolts (one at a time!) and
replacing with a length of threaded rod with a nut. Then, when all are fitted, slowly and
equally, run the nuts down the rods to relieve the pressure. These cars are no lightweights, and the
springs obviously need to be powerful, so care will be required here too.
The observant
amongst you will have noticed that there’s only one brake caliper. I’ve no idea what’s happened to the other
three, I guess the previous owner wanted them for something! I have managed to buy some replacements
though, which are currently soaking in Plusgas, and I
will attempt to strip those down too in a few weeks.
The steering is an old design with a steering box and apparently takes 5 full
steering wheel rotations from lock to lock. The ratio needs to be this low as
the car is heavy and has no power assistance. Many owners have replaced this
set-up with a more modern power assisted ‘rack and pinion’ system from an
XJ6. Because it’s longer than the
original, it does change the dynamics and introduces slight bump steer and puts
out the Ackermann angles. As I do not intend to be
pushing the boundaries of performance, and really don’t mind if the tyres
squeal on full lock, it’s something that I also intend to.
Before I fit the running gear, it makes sense to spray the engine bay as access
will be restricted after the subframe and engine is refitted. I took it down to the metal to ensure a good
finish, and have applied a coat of primer.
I’ve decided that the original ‘Sherwood Green’ of the car is not for
me, and my intention has always been to change the colour to a metallic grey,
so the engine bay will have a couple of coats of that when it arrives. I just hope it doesn’t get too damaged when I
refit everything.
Yesterday I had an opportunity to attempt to remove the rear axle hubs. I am going to replace all of the seals and
gaskets on the rear axle, so to do this the removal of the hubs is
required. Another reason to remove them
is that they are for the 5 stud steel wheels, and not the new wire wheels I’ve
just bought, so they had to come off regardless. The removal of hubs in general is not easy,
but the shallow taper of the shafts on these old Jaguars made them so tight and
difficult to remove, a special too had to be produced to facilitate this. I did try to obtain a loan of one of these,
but they are very difficult to source, so I bought the best puller I could
afford and used other recommended techniques which also help. The first thing I’d been told was to reverse
and leave on the castellated nut on the end of the shaft as the threaded end
can mushroom or balloon such is the pressure involved. Then I’d read to insert a copper or bronze
spacer between the pushrod of the puller and the end of the shaft. This apparently acts as a buffer between the
two steel surfaces to stop damage. I
didn’t have any copper rod or bronze, so I used a couple of old pennies
instead. They were perfect as they are the
same diameter as the shaft and just fitted inside the nut. I drilled holes in them so that the pointed
end of the puller didn’t wander.
To prevent the hub rotating as I tightened the puller, I chopped a bit of angle
iron to act as a stop. But then the
puller legs wouldn’t sit straight on the hub because of the thickness of the
steel under two of them, so I had to make up three spacers for the remaining
legs to ensure the whole assembly sat flat and true. Initially I heated up the hub with a
blowtorch, but then also enlisted the help of my hot air gun too. I set both up to direct their heat at the
assembly and left for an hour.
Things got hot, too hot to touch that’s for sure, but not as hot as I’d have
liked. The problem is that it’s a lot of metal to heat, and it’s hard to add
heat quicker than the large circular heatsink can dissipate it. Anyhow, I started to increase the pressure on
the puller with the aid of my 24” breaker bar, stopping after every quarter
turn to give it a good whack in an attempt to shock it off. Just as I got to
the point where I thought that something was going to get damaged, there was an
almighty ‘crack’ and the hub popped off. To say I was jubilant would be
somewhat of an understatement. I
disassembled it all and everything looked good with no damage to the shaft
which is the best news.
Armed with my ‘winning formula’ it was time to try on the other side. The pennies were destroyed, so I had to
replace those and all went exactly the same except the hub popped off without
quite so much pressure required. All in
all a fantastic result. Others have
really struggled, so it was a job I’d not been looking forward to. Here’s a link to a video of a guy called Vic
attempting the same job. His YouTube streams are quite interesting and
entertaining. It will give you an idea
of just how difficult this job can be and well worth a watch.

So the rear hubs are off and I removed the front ones too. The fronts are a piece of cake in comparison,
the hub nut on this design isn’t even tightened up. When assembling them, you tighten until the
wheel has just a little bit of resistance, and then back it off a turn, then
pop in the split pin. It’s quite
unnerving that it’s all so loose, but apparently it’s because the bearings heat
up quite a bit in use, and they would start to bind once warmed up. One other unusual thing I found is that the
rear disks are actually a larger diameter than the fronts. I’ve never seen that before.
I now need to get the disks to someone who can give them a quick skim, not so much
because they are worn (in fact there appears to be next to no wear at all) but
just to clean them up a little and ensure they are
true with no throw.
Using the
engine hoist I lifted the rear axle onto my old trusty BT trolley so it’s at an
easier level to work on. The workbench
would have been better, but would also have taken up all of my workspace. I managed to remove the differential sump
plug and drained out the old oil. Not
very pleasant at all, it was really dirty, but fortunately no sludge.
The rear
cover was popped off next to expose the gears of the diff, it was only at this
point did I realise that one of the driveshafts had actually seized. Not really what I wanted and had a sleepless
night worrying about where it was seized.
If it was one of the gears of the diff, then the rear axle would be
toast, and a new one would need to be sourced (and paid for!). The only way to confirm where the problem was
is to remove the driveshafts. As luck
would have it, a few weeks ago, a neighbour of the garage gave me an ancient
old puller. The weight has broken, but
still works fine.
After I’d
removed the driveshafts it quickly became obvious where the problem lay. The outer bearing (wheel bearing) had
completely seized and the planetary gears of the diff could now spin
freely. A big, big relief. So with the
driveshafts and propshaft flange removed, it received a final clean over before
a lick of paint. I fitted a new oil seal
on the pinion and then refitted the flange, but I haven’t had a chance to fit
the new wheel bearings just yet. They
are an extremely tight fit and I want to take my time and not damage them in
the process. I’ll probably use some heat
to ease them over the driveshafts.
Yes, I know the pinion retaining nut is loose, I didn’t have the torque
settings at hand. Better to leave it
‘obviously loose’ so it’s not missed on reassembly.
After refitting the diff cover, I started to dress the axle, starting with the
brake pipes and fittings along with new wheel bearings. I’m unable to refit
anything else as the brakes are not refurbished yet, the disks need skimming
and the guards need painting.
These are the torque arms which, along with the leaf springs and Panhard rod,
hold the rear axle in place. Needless to
say the bushes needed replacing. They
were so badly rusted in place, that neither my biggest hammer nor the vice were
able to shift them. I managed to drill
out the rubber section and remove the bush centre sleeve, which gave me hacksaw
access to the bush outer. I cut through
it taking great care to only just break through so that the arm did not get
damaged. Then the bush outer was twisted to remove.
New bushes ready to be inserted
Despite cleaning up the mating surfaces and applying grease liberally on both
parts, it was a real struggle getting the new bushes in, and the pressure required
bent the arm of my vice. I really need to make myself a hydraulic press.
Eventually however, they all went in OK.
The next item to get some attention was the rear leaf springs. Each leaf had to
be carefully praised away from its neighbour and the end bushes of these need
to be removed and replaced in a similar fashion to the torque arms. Ready for
paint now.
As you may remember, the car came without brakes except for one at the
front. I bought some rusty rear brakes
from eBay, better ones are just so expensive and I intend to completely
overhaul them anyway, even if they were in good condition. I removed the pistons from both callipers
without too much of a problem until the last bolt. It’s always the last bolt! It started to round off with the correct
imperial spanner, so I applied some heat and hammered on the next smallest
metric spanner. It was a tight fit, but
not, apparently, tight enough. That
started to round too. Last resort was to attempt to use a nut remover
tool. It’s never failed me
before…..until today. Even that didn’t
grip so it was down to the last, last resort.
I’ve never done this successfully, but I have seen many YouTube videos
of it working, so worth a shot. I welded
a larger bolt to what remained of the jammed one. I’m not sure if the extra heat of the welding
helped too, but I gently eased it around with a long lever on the larger
spanner and managed to work it loose. That was relief.
It probably
would have been better if I’d managed to weld it on straight!
I bought these callipers a few months ago, and since I’ve had them, they’ve
been in an old washing up bowl and every few days I’d spray them with some Plusgas releasing fluid.
But even after all that time, and all of that fluid, the bolts and holes
were completely dry. As you can see
above, even the area under where the piston attached is bone dry. So are we wasting our money with these
expensive products?
Anyone else think these rear brake callipers look like lobsters? No… Just me then.
So they’re
completely disassembled ready for cleaning and painting.
The main parts are intact, but unfortunately some of the smaller components
(return springs, pads, bolts and retainers) have suffered over time, so I need
to order some more before re-assembling the rear brakes.
I gave the springs a coat of paint ready to put back together but the clamp
bolts had long gone due to rust. New
replacements weren’t an option as the threads in the side of the clamps had
suffered the same fate. So I made some new ones from some stock bolts. They needed grinding down to remove the
thread and a taper put into the head so that they sat flush.
I welded in the side which was previously threaded, but I don’t foresee them
ever coming out again, so that’s fine.
Here they are in their new home on the fully assembled springs. As you
can see, the bushing, centre mounts and rubber pad have all been replaced with
new. The pads between each leaf were still serviceable, and were reused along with
a liberal coating of motorbike chain-lube.
This sets like paste almost, so won’t drip out and will hopefully stop
them from squeaking for many years.
I hate
working under cars these days, so I’m doing as much as I can whilst it’s on the
rotisserie. Here I’ve run the petrol and brake line. They’re fitted into rubber
covered ‘P’ clips which in turn are screwed into Rivnuts along the chassis
rail. You can see the exhaust heat shields have been fitted on the near-side,
and now that the lines have been run, I’ll fit the off-side too.
Bit of a messy image, but this is the front subframe on the trolley ready to be
dismantled.
Dismantling was straight forward enough, but unloading the pressure from the
springs was a little hairy. I'm never keen on working with coil springs, but
you can't even use clamps on these due to the lack of room. I'd read online a
few methods and opted for what I considered the safest, or rather least
dangerous. First off I bought a huge
pair of nuts (no, the threaded variety) a length of M16 studding and a handful
of washers. After removing the shock absorber, I made up a small plate for the
lower spring retaining plate and inserted the studding instead. I used 2mm
steel, but it bent quite a bit when the full pressure was applied (see the
photo!), so I'll be using something thicker when refitting, much thicker! I
chose to drill a hole in the top nut and inserted a split pin to prevent the
top nut undoing instead of the intended lower one. All went as well as can be
expected and now the subframe is completely bare, but yes, thicker plate next
time!
Here you can
see the plate at the bottom of the threaded rod, bending under the load of the
spring. I am just glad the hole didn’t
enlarge enough for the washer to pop through!
The wishbones,
uprights and springs were cleaned up and given a quick lick of paint, along
with new bushes.
Then the same fate for the subframe.
Having got
away with using 2mm plate for the removal of the springs, I thought it wise to
use something much thicker to re-compress them.
Long studding threaded into the lower wishbones to guide the bottom plate up onto
would have been the best option. But in
the absence of any, I used a couple of old bolts with the heads cut off. Not ideal, but it worked rather well. I don’t think 'comfortable' wouldn’t be the
right word, but it's the first time I’ve not been absolutely shitting myself
when compressing coil springs.
Rinse and repeat for the other side….
One of the last things I needed to do on the underside was to route and
terminate the petrol pipe. I had some
trouble with finding the correct size fittings, and after buying three unions,
I still didn’t have one that was a direct fit, so I modified what I had and it
seems to work well. It looks innocent enough, but this is one job that would
have been very tricky to do under the car as I needed to access the top section
via the boot whilst also tightening up underneath.
I did
originally intend to re-use the brake disks and have them skimmed, but after
some investigation, it appears that they were supplied on the cars as a
‘consumable’ item. They were machined
and supplied such that there isn’t enough material to be able to skim the disks
and still maintain the minimum thickness.
So, new disks it is. However,
they are so reasonably priced that I think having them skimmed would have
actually been more expensive than buying new.
Unfortunately the same cannot be said of the new hubs. The old steel wheels use a standard five stud
fitting, but as I’ll be using the chrome wire wheels, they need to be fitted
onto splined hubs. Buying them hit me
hard in the pocket, but when the chrome wire wheels are fitted, I’m sure the
improvement to the look of the car will be worth the cost.
So, the rear
axle is ready to be fitted. Not too much
of a problem, I sat it on a pair of axle stands and lowered the car down on the
rotisserie to meet the axle. I’ve
assembled everything, but nothing has been tightened up as I want to ensure
that it’s all sitting correctly first.
Also, if the rubber bushes are tightened at their lowest position, they
will be stretched too far at their highest position. Better to set correctly at the centre point,
then this way the flex will be half each way.
I’ve not yet bought the rear shocks as they are easily fitted at a later
point, unfortunately I need to prioritise my spending on components that will
hold me back if not available. One thing
I needed to change was the OS rear brake pipe which was damaged during the
installation. It got trapped between the
axle and a support. It’s an easy fix,
and didn’t take very long, but still annoyed with myself to allow it to become
damaged in the first place. Also in view
is the new Panhard Arm which prevents lateral movement of the axle during
cornering.
So, with the rear axle almost ready to accept the wheels, it’s time to refit
the front subframe. I will wait until
the subframe is fitted before adding all of the ancillary items. The subframe is incredibly heavy on its own and
is a handful to move around whilst refitting.
If the hubs, disks, shocks and brakes had also been attached, it would
have made the job far more difficult. I
managed to scratch some of the underseal coating on the inner wings as it was,
but with the additional weight, I’m sure it would have suffered further. I will refinish this when everything has
been completed.
In the
1960’s, the Jaguar MK2/Daimler V8’s were the first production car to feature
rear brake discs as standard, but the Achilles heel is the single circuit
pipework which operates them. This means
all four brakes are operated on one brake pipe and introduces a single-point-of-failure. As the car is also an automatic, there’s not
the option of engine braking as a last resort either. The only way to overcome this, is to upgrade
the brake master cylinder and servo to a more modern dual circuit system. I wanted to keep with Jaguar components, so I
bought a complete unit from a more modern vehicle. Because the car has large wings, the engine
bay location for the unit sits further to the middle of this car than its
donor. This resulted in the brake pedal
being too far to the left in the cabin.
I didn’t want to bend or weld the pedal arm for obvious reasons, but
fortunately a pedal sourced from a Left-Hand-Drive version of the car from ebay, returned the foot pad back to the correct position.
The footprint of the new unit is far larger than the old. Above you can see the difference in size and
I needed to fabricate a sturdy 3mm steel plate to ensure a solid mount.
Fitted loosely in place. I need to lift
the front so the pedal rests at the correct height and there is sufficient
travel to accommodate the maximum braking position, then I’ll weld it into
place.
The new unit, which previously housed the accelerator pedal too, required
trimming to fit around the engine bay brace. I’ll be retaining the original rod
accelerator system as it also incorporates the auto-gearbox linkages, so I
won’t be using it anyway. The only
issues I currently have is that I’ve taken up some of the room that the battery
and the wiper motor previously occupied. It will require a creative
solution…….The battery will probably be mounted in the boot (I’ve already
fitted rivnuts for the cable along the chassis leg in preparation for this) but
the wiper motor is something I’ll deal with that later. Below you can see the two brake line outputs
under the reservoir. I’ll be using a
simple front/rear split system, one circuit for the front brakes, and the other
for the rears.
Before I complete connecting up the brake and fuel lines, it makes sense to paint
the engine bay first to save me from removing it all again later. The colour I’ll be spraying the car is Jaguar
Pearl Grey which is far nicer in my opinion than the Sherwood Green it was born
with. It’s quite a new colour and was
never an option back in the 60’s, but my aim for the car has never been for
absolute originality so I chose the colour I liked. Many people choose Gunmetal Grey, but this is
slightly darker and has some red in it too, which lifts it a little compared to
the more monochrome of the Gunmetal.
Anyhow, I covered the wings with the free masking paper that Cardiff
Council provide, and set about spraying the bay. You can see the finished plate that the new
brake servo sits on. For this relatively
small area, I opted for rattle cans. A
couple of base coat followed by a couple of clearcoat.
Once this had all dried, I started to reassemble the bay components. The brake
servo, minus the master cylinder, was loosely bolted followed by running the
pipework. I had to deviate the original
routes as the servo is now in a different position. Once they were clamped to
the inner wing struts I fitted the lower steering linkage and steering column.
The steering is now complete and once I lower it off the jacks, I will be able
to steer it around the garage and outside which will make things a bit
easier. I replaced all of the bushes,
universal joints, rubber boots and bolts here, same as the rest of the steering
system. I was very pleased to feel that
there is zero slack or movement and the steering wheel input feels very
positive indeed with the wheels responding instantly.
To complete the rolling shell, I just need to refurbish and refit the brake
calipers and handbrake cable. You will
have already seen the rear calipers being refurbished, but the pistons for
these, along with the front pistons will need some attention. The calipers hold two pistons each, so that’s
a total of eight pistons to refurbish.
After an inspection, I would say that there is only one, possibly two,
which are good enough to use as they are.
The rest will require a re-sleeve.
This involves boring out the old sleeve, pressing in a stainless steel
insert, boring it out and then honing to the original diameter. This will enable me to reuse the original
pistons. I have all of the new seals I
need, but unfortunately the re-sleeve will be a little costly and I’ve not
found anyone to do them yet. Here are
the best and worst for comparison.
I’ve been working on the engine for a while, but I’m waiting for some parts to
arrive, so in the meantime I’ve revisited getting the chassis not only rolling,
but stopping too!
I failed getting the brake caliper bores re-sleeved, so I instead refurbished
the best of them from the large collection I seem to have accumulated over the
past year or so. Some were good, but a
couple were just ‘Acceptable’. So I
cleaned up the caliper frames …….
….. and mounted the pistons/hardware/pads/pipes. Oh, and painted them too.
On the car they look quite nice and the red will show through the wire wheels.
BUT! The bores aren’t 100%. So, after a few restless nights, I decided
that less than 100% would just not be good enough. They would never fail, and at worst I may
have a few drips where they could leak a little. But I’d rather get them the
best I can. Buying new pistons was an
expensive option, (£400 for the fronts only), and would only replace the
brakes, rather than improve them. A
common upgrade is to use the four pot calipers from a Volvo 240. These are much more powerful, only require a
little fettling to get them to fit and are only £69 per side. Plus they are brand new! No more sleepless
nights. So, off with the old ones. The
work on them is not wasted though, I can use them for the rear calipers where
they’ll be less important. Obviously
they’ll also get replaced if they do happen to drip any fluid in use.
So, whilst I wait for them to arrive, I did some plumbing. The master brake cylinder is now dual circuit
as you may remember, so the brake pipe from the rear of the car was fed into
the one circuit and other for the front was run in around the engine bay. The old master cylinder and booster (old name
for servo) was located through the inner wing.
As this has been ditched, the hole that remained has been filled with a
patch panel bolted in instead. I may end
up welding it in, simply to improve the aesthetics, but it doesn’t look too
bad, and when the engine is back in it probably won’t be seen anyway.
They’re here
already!! This is a comparison of the
old and the new. They are far beefier
than the old ones and will provide far superior braking, plus they are a more
modern design, brand new and will be easier to service in the future. I’m super
pleased with them but they will need a little fettling to get them to fit. The mounting holes need drilling out a
smidge, the offset needs correcting by a few millimetres (shims) and the
standard discs are too large by a few millimetres too. Oh and they’ll need painting red obv’s.
All of that is easy enough to rectify. I
started with the discs. I could have
removed the discs and taken them to an engineering shop to be cut, but a far
easier and simpler solution is to grind them at home, oh and did I say cheaper
too? As luck would have it, I had just
bought a new grinder, so the stones are nice and square. They took about an hour each. I have seen companies that actually skim the
discs this way too.
One thing about using these calipers, and something that I only realised
yesterday, is that there are two independent inlets. One inlet feeds the top opposing pistons, and
the other feeds the lower opposing pistons.
This is all fine and dandy, but when you have a single hose to attach,
there’s something of a mismatch. The only way to connect things up to work
correctly, is to use an inline splitter.
I have fitted these on the rear axle and also under the bonnet for the
pipework to feed each side of the car.
The problem here is that there is very little space, and when you are
working with bespoke solutions, you can’t simply buy something ‘off the
shelf’. However I tackle this, it needs
to be operationally perfect whilst not fouling on anything when the steering
moves from lock to lock. A neat look would
be desirable too, but obviously lower in importance than the other
prerequisites.
So I spent far too much time today, trying out different configurations,
increasing in complexity as I tried to make things that weren’t designed to
fit, fit. In the end I pushed the
pipework to the extremes and crammed it all in behind the pistons. I realise that it looks a bit like an airing
cupboard from the 80’s, but this is the best I could come up with. The saving
grace to all of this though, is that it will be totally hidden behind the
caliper when in use. Only myself and the MOT man will know, oh and you lot of course!
And here it is fitted. I need to get the pads in there of course and connect
the pipework, but you can already see what a massive improvement it is over the
stock components. So, I have to do
exactly the same now on the passenger side.
And after some paint …..
I’ve been looking for a good second-hand pair of exhausts since I bought the
car. A new pair start from £700 plus all
of the fitting kit and clamps on top.
I’ve never seen anything worthy of buying in that time…..until now. I have an alert on ebay
to inform me of any new items, so when a pop-up appeared for a brand new system
in stainless steel with a fitting kit for £250, I clicked the buy-it-now button
before I even knew where they were! They
weren’t local, but a round trip of 250 miles later, they were in the
garage.
Upon
inspection, there was one part that I wasn’t 100% happy with. I have been alerted to this and it seems that
this is the way that all of the aftermarket exhausts are made. However, it didn’t really sit right with me,
and I set about rectifying it. The
problem is that the car, being a V8, has two parallel exhausts for the full
length of the car. And, for reasons that
are far too complex for me to understand, have either an H or, as is the case
on more modern cars, an X shaped section in the middle to combine the two
otherwise independent systems. It has
something to do with the pressure balancing but to be honest I got bored when I
started to read up about the science behind it.
Enough to say, my car has a H section and
that’s where the issue is. The pipes
that make up that part have been welded together ‘but’, where this has been
done there is a significant surplus of tubing left inside. Here it is and it’s easy to see how this
excess pipe will cause a disruption to the flow of the gasses.
Not being
happy with that, I looked at how to remove the excess which is 6” down a tube
and not really easy to access. The only
solution I could come up with was to use a hole cutter
attached to a long socket extension bar.
The hole cutter blades stick out somewhat from the tool’s bore diameter,
so I had to pack out the outer edge so that the cutting blades did not damage
the inside of the tubes.
It went more
smoothly than I’d anticipated, and in 10 mins both exhausts had the extra
material removed and would be far less restrictive.
So, next job
was to attach them to the car. First up
the downpipes were connected to the exhaust manifolds and secured with crush
tubes and new brass fittings. This was straight forward enough, although a bit
tricky to gain access to the uppermost nuts to tighten fully. I got there in the end although it highlighted
another issue. When I ran the fuel and
brake lines in the shell, the engine was obviously not fitted. Now that it is, I found that the exhaust pipe
was very close to both lines. I
initially covered the exhaust tube in some heat-resistant wrap which should
reduce the heat that the pipes would be exposed to.
But, after a
sleepless night, I decided that I was just not going to be happy until I had
some distance between these. So, out
they came and I refitted them in a better position. The copper brake pipe was easy enough, but
the fuel line is made from kunifer, which is a far
harder material. Some blasphemy and
huffing & puffing later, I did manage to re-route the pipes to a position I
was far happier with. Unfortunately, because the route was now further up
towards the front of the car, it meant that I needed to cross over the
pipes. Not ideal, but not the end of the
world either. So a day later, I ended up
pretty much back to where I started, but at least I can sleep easy tonight in
the knowledge that the fuel lines are not going to boil the petrol when the car
is running.
So, with this
oversight now rectified, I continued with the next sections of the
exhaust. The fixing kit came with the
standard u-bolts, but they are far from ideal,
despite being used for most exhaust applications. So instead I sourced some superior Mikalor clamps in the two diameters used on the system and
used high temperature silicone to ensure an air-tight seal. Here, the H section
is now complete and only the silencer section left to attach.
The last parts of the system may be not as straight forward to fit, because
I’ve not made cut-outs in the rear valance for the exhaust ends. I left this intact intentionally as I wanted
the make the apertures in exactly the right place, and I wouldn’t know that
until I offered up the exhaust, so that’s next.
One thing
I’ve heard about the aftermarket mounting brackets is that they are susceptible
to splitting, so I have always intended making my own. I cut out shaped pieces from an old conveyor
belt. It’s cheap, flexible and has a
reinforcing mesh which should give it the durability and longevity I need. The mid-section mount is located forward of
the exhaust tag so required a small spacer.
I found it to be rock solid and should provide a vibration free
mount. I appear to have compressed the
rubber a little too much here. Next time
I’m under the car, I’ll slacken it a smidge.
The rear/tail mount was similarly cut and fitted. I’m extremely pleased with the results and
think they’ll be good for many years.
Obviously, as
the engine is a V8 configuration, then this needed to be done on both the
nearside and offside. However, before
sealing and final fitting the nearside exhaust, I have to fit the fuel tank
first, as the tail section route makes fitting the tank afterwards difficult.
So, the fuel tank. This has been a right
pain. The tank that was on the car was
toast, and with brand new aftermarket models costing from £700 for the bare
tank, I searched for a good used replacement for a while. After buying two which almost fell apart
after a good rub down with a wire wheel (mud, fibreglass patches and underseal
can hide a multitude of sins I’ve discovered to my cost) I needed to source
something good this time. I spotted an almost new one on ebay
with a low start price. Long story
short, I had to part with £220 and had a long journey to collect it, but here
is the final one. It was indeed as good
as it looked, even after a wire brush down.
I’ve given it a coat of rust preventative paint and then a gloss one to prevent
dirt building up. I also gave the
bottom half a coat of Gravitex (posh underseal) so
that any stones thrown up will not chip the newly painted surface. This photo
is before the Gravitax was applied.
The inside of the tank is clean but there are some patches which have
discoloured a little due to oxidisation (I don’t want to say the R word,
because it isn’t real rust, just blemishes really). I bought a 5 litre can of Evaporust which I
will swoosh around and leave for 12hrs to remove this.
Update June 2022
The tank is now in, and now that it’s in place I was able to fit the remaining
exhaust pieces. Not possible to fit
before as they overlap on the nearside.
A friend offered me a pair of rear handbrake calipers. I had already rebuilt the actual rear brake
calipers (remember?) and the handbrake calipers were the last bit to get the
brakes fully working.
They weren’t in great shape.
But, like all mechanical things, they can be stripped and rebuilt (after
removing the dead spiders!)
Here they are attached to the main calipers.
The handbrake cables were then refitted and lubricated and they all
appear to work correctly. So, time to
fill up with brake fluid and see if (or perhaps, how many!) leaks I had to deal
with.
Well, you’ll be glad (maybe surprised?) to hear that there were no leaks and
after fully bleeding the pedal pressure is great. So, that’s a bit of a relief.
