Rear end stripped down and back together again

Time to get this up to date again. Some weeks ago I stripped out the rear spring and driveshafts from the GT6.




First part of the refurb was to pull the transverse leaf apart, so it could be cleaned, lubricated and wrapped with denso tape. It was quite easy to pull apart, fortunately there were no seized fasteners as the spring is probably only ten years old. No pictures of the finished spring, but here is one of it with all of the leaves separated.




Then I was onto the CV's to search for the slack. Upon stripping the CV's down it appears that detritus has got into them, pitting the bearing surfaces and balls, hence the slack.




The entire CV's were replaced with better clips on the boots to prevent a reoccurance and following a suggestion from Nick Jones, the CV's are now held even better in place on the driveshafts with the addition of bearing lock and the appropriate number of washers between the CV and securing circlip.

Since then the GT6 has been out for a couple of runs, including to a local classic car gathering and has performed beautifully, proving that the works were successful. Unfortunately I've not had much time for the car since then as I am heavily involved with a much larger restoration project and wonder if it's time to look for a new home for it?

Driveshaft investigations

For the first time since it's MOT a few months ago I've been spending some time on the GT6 (SS Freshspring has been keeping me pretty busy recently) First off was a clean and wax, which it hadn't had for far too long, then it was onto a bit of investigations.




One of the reasons that I have not used the GT6 much was due to a noise from the rear I could not identify at the time. Initial investigations showed some slack in the inner CV joints, so a replacement pair have been sourced and this weekend I got the back end up in the air to remind myself what was involved in the task. As the weight came off the back end I could hear that previously unknown noise coming from the rear transverse spring, ah, that'll be cause of the noise then. I could just spray a mass of oil at it, but seeing as it would not last and I need to disconnect the spring to remove the driveshafts, I may as well pull the spring all of the way out, service it and cover with denso tape to prevent a repeat of the problem.
The reason for doing this investigatory work is that the last time I had to dismantle the rear hubs the trunnions were seized, creating much more work and bush replacement. Fortunately they proved not to be seized this time, proving that the anti-seize compound I used last time has worked.

Next step is to strip it all the way down, find the right lubricant for the spring and source some denso tape.

Still alive

It's been a few months since I last ran up the GT6 so the battery charger went on midday Friday and after work that day and quite a bit of cranking to get the fuel back through to the injectors she fired up. Just a quick run around the block but enough to free off the brakes and get up to temperature.
And the reason for leaving the GT6 for so long? I'd noticed that the inner CV's were starting to get noisy and slack, so I have not been keen on going too far until they have been replaced, that and I've been increasing busy with SS Freshspring.

I have another pair of CV's to fit once I have checked them, there is space in the workshop and I can find a clear day or two to fit them.



One day I'll get around to building up a new balanced bottom end for the engine using the brand new crank, VP bearings and +60 pistons I have ready and waiting, but for now it seems to be holding up quite well as I've not pushed it for too long at the upper rev range.

And it's back

A couple of weeks ago, approximately two months after the accident, I collected the GT6 from Backwell near Bristol. The car was not exactly as it was prior to the accident, but I never expected it would be. Having spent many hours over the years getting just how I wanted it, I'd have been pleasantly surprised if it was put back to its former self.
Just to complicate things, I sent the GT6 to the garage on my spare steel wheels (with older tyres fitted) so I could clean up the alloys while it was being repaired, this meant I had to re-fit the alloys before I could drive anywhere and would have to fit the four steel wheels into the back of the car, not too had really. However, my plan was to drive from Bristol to Cambridge for a steam weekend at the Cambridge Museum of Technology, so that's an over 400 mile round trip in a car that has only just been repaired and hardly run for the past two months, fingers crossed eh?

With the wheels changed over, the car given a once over and the paperwork signed off, my first stop was to the petrol station as the tank was very low. The mile long trip was a little peculiar feeling, having been in that modern spaceship of a car the previous two months, and the engine was not running right, it felt as if it was not firing on all cylinders at lower revs, but was OK once opened up. Once safely at the petrol station and with a fresh tank of fuel, I had the bonnet up with the engine running and felt along the injector lines to find that No.5 line was not pulsing like the others, ah, that'll be a partially blocked or air ridden injector and easily solved by withdrawing the injector and flicking the end of it until the steady spray pattern comes out. All reassembled, I set back on the road with the engine much happier, heading for the M5, M4 and Chippenham as I had another stop to make before I got to Cambridge.
A week or two before the planned trip to Cambridge, thinking I would still have the hire car, I offered to collect a Triumph 2000 door from Bill in Chippenham and bring it Cambridge for Pete to pick up. So somehow, Bill and I managed to fit the door into the back of the GT6, along with the four steel wheels and all of the odds and sods I needed for the weekend.



The rest of journey to Cambridge then back home to Wales was fairly uneventful, though I did have to stop a few times to re-adjust the bonnet cones, as the bonnet catches would come undone, allowing the bonnet to rise and wag around at speed, also there was the need to re-position the wiper arms as they were hitting the bottom of the screen and not clearing the rest of it properly. Mind you, I was glad for a reason to stop more often as going back into a manual steering car after a long break; I was getting pains in the side of my neck and upper arm.

So what next? The GT6 could do with a service as the engine still occasionally stumbles a bit at low revs, and then there is the rev counter, which looks to have failed in the impact. I was given another one as we noticed it had failed when I went to pick up the car, but I will need to change the internals around again to have a GT6 rev counter with the required indicator lamps built in, along with the electronic rev counter. The bonnet fit could be a little better, as it is bit high at the front, but cannot go any further down until the radiator shroud is repositioned. If we have a warmish day I ought to get some Dynax rust protection into the bonnet and new chassis parts before it has a chance to rust.

And longer term? I feel I have fallen out of love a bit with the GT6 and have a few times considered selling it, though I'm not sure what I would buy next, TR6? 80's Range Rover? The issue is that I use the GT6 as an everyday car and could do with a bit more space inside for moving things around and have a more comfortable driving position with better road presence.
I wonder if a Herald estate would suit the bill as a second car? ample space, simple (and familiar to me) mechanicals, with the possibility of an engine change or electronic injection for better driveability and economy.

Damage assessment

So it's almost three weeks after the accident and things appear to be moving on fairly well. I've had a quote for repairs to the car, been visited by the insurance assessor and have been told that it will be repaired by Ian at CCR, who did the paint and panel work a couple of years ago.

The GT6 replacement/repair list stands at;
Bonnet assembly,
a new headlight and surround for one side.
Both front plastic overriders are broken,
the bonnet hinge boxes and ends of the front chassis member have been distorted.
Bumper is scrap.
Both front 1/4 valances are slightly distorted on the top rear edge where they have impacted with the wheel, but may straighten out.
The drivers door has been knocked as the bonnet has hit it.
There are small paint chips on the bulkhead from the impacting bonnet and a slight dent on the drivers side bulkhead below the windscreen on the corner where the bonnet has hit it with more force.
Radiator and the coolant swirl pot is mangled.

One thing which has come to light is the personal effect it has had on me, with the usual whiplash injuries (neck, back and arm ache) but my breathing capacity also seems to have been reduced, in part I believe due to the seatbelt.
In my GT6 I have the standard static seatbelts, which I was quite happy to use, having had problems with the recoil belts in my old Spitfire. I am now seriously considering fitting recoil seatbelts as per the later Spitfires in an attempt to reduce any possible future injuries, it will need an extra hole and strengthening plate in the rear wheel arch, but should be worth it should something similar happen again.

So I'm just waiting on arrangements for the GT6 to be taken over to Ian and hopefully by the time it has been repaired I'll be in a better condition to handle the manual steering and brakes. While I wait for my car to be repaired and returned I have been supplied with a hire car, a Citroen DS5. The Citroen is a veritable space ship in comparison to my 40 year old Triumph, packed with various electrical and electronic gizmo's such as auto lights and wipers, reversing camera, built in sat nav and electric handbrake, the last of which I have still not fully got to grip with.

It's been a while

It's been over a year since I updated this blog, mainly because I haven't had much to say. In that time the GT6 took me to my first autosolo at Bovingdon and a track day at Goodwood. All was going well until I took a trip to the motor museum at Gaydon, only to find a catastrophic failure of the water pump when  I tried to head home, so that meant waiting around for a few hours on a cold February evening.

I've tried to take a break from working on the car, instead just enjoying it for what it is. My latest project is an old steam ship called Freshspring, which I seem to have got involved with as an active volunteer and society secretary amongst other roles. If you want to know more about the ship, there is a website, http://www.ssfreshspring.co.uk/ and a Facebook page, https://www.facebook.com/SSFreshspringSociety

Unfortunately, while driving to the ship last night I was coming around a corner to find a courier van coming straight towards me on my side of the road. Brakes were fully applied ( I don't remember doing it, but I must have) but there was contact.



The insurance company has been informed and I'm now waiting on a quote for repairs.

A dashing time and Bovingdon Autosolo

The workshop I sometimes use was free for a week, so I set about making a start on the dash. Previously it looked like this;



The left and right panels are from different Spitfires and there was a redundant hole for the hazard warning light on the middle panel. The panels were removed from the car and all the switches moved as required, on this centre panel you can see where the hazard light was.




I cut a piece of wood to fit in the redundant hole and left it overnight with glue and a clamp on it, which meant the following morning I could remove the thick varnish and previous layer of veneer.
The veneer came off quite easily, using a mix of sharp chisels and various grades of sandpaper discs on the angle grinder.



I'd bought some American walnut iron-on veneer the previous week, as apparently that was what they used originally. I'm no originality freak, but I'm just not all that keen on the burr or dark finishes you can see in some Triumphs.
Anyway, I followed the instructions which came with the veneer, leaving an edge all around the pieces, so the veneer is stuck onto the dash panels. As suggested, it was left for 24 hours for the adhesive to cure before I trim them to shape and give them their first coat of varnish.




Once cured, I could trim the veneer, this could be done using a very sharp knife, but it still took over an hour as any mistakes would be hard to hide.




Then I could start building up the layers of satin varnish, it had a total of five coats. In between varnishing, work started on modifying the wiring loom again, adding in wires for the rear fog light and wiring in the 12v lighter socket, map light and radio.
With the loom exposed I could also work out why the light for the ignition barrel was not working, it turned out that the original loom had two wires each from the fuse box for the roof and ignition barrel light and I had split them. This had the effect that the ignition barrel light would only come on when the ignition was on, not what you need really when it should come on as you open a door or switch them on on the dash.




The cured veneered and varnished dash pieces could then be fitted back into the car, followed by the gauges, steering column and gloveboxes. You can see in the picture below that a radio has been fitted also, originally I was not going to bother installing a radio, but as this is my only car I was starting to miss having one. I'm loathed to drill a hole in the bodywork for an aerial, but fortunately I noticed that my mobile phone has a FM radio built into it, which means I can connect it to the car radio instead.




All this work had to be completed by last Saturday at the latest as on the following day I was booked in for a Autosolo at Bovingdon, near Hemel Hempstead. Scrutineering ended at 8.45, so it meant I was on the road at 5.30 to get there in good time, but having travelled a few miles down the road I noticed that the indicators were not working, damn.
The next half an hour or so was spent checking fuses, switches and relays, trying to work out what was wrong. After a while I worked out that the flasher unit was not getting any power, despite the fuse being OK, so I found a piece of wire in my tool box to make a temporary connection, it worked so I could get on my way again.

It was my first attempt at a Autosolo, I thoroughly enjoyed it despite the early start and impromptu road-side repair. In my class I came 10th out of 15, though it probably would have been 12th if one car hadn't retired due to gearbox problems, but for a first try I can't complain at that.

The following day back home I could take another look at the indicators and with the wiring diagram at hand I managed to diagnose the problem fairly quickly. The power for the indicators passes through the hazard light switch, so they can be disconnected when the hazard lights are switched on, but the hazard light switch was not returning to the correct 'off' position, preventing a connection through for the indicators.
It was a quick fix to get everything working again by making an adjustment on the hazard light switch and a relief that I hadn't messed-up anything while working on the loom earlier in the week.
