I've now completed my clutch change, ready for a couple of runs up the hill climb course at Prescott in 10 days time.
The old clutch was worn down to the rivets on the pressure plate side and had worn a tell tale groove on the pressure plate surface..
There was still a little bit of friction material above the rivets on the flywheel side so luckily there was no damage there. The new clutch is much lighter in operation than the old one and is biting much lower on the pedal travel, another sign that the old one was past it's sell by date! While the gearbox was out I took the opportunity to clean out the overdrive filter and the overdrive engagement is now much quicker with a clean filter and a change of gearbox oil.
One little tip for all you overdrive Triumph owners out there. The fixings for the overdrive gearbox mount are really difficult to do up or undo without the aid of an assistant unless you've got 4ft long arms like a Gorilla as you can't reach the bolt head inside the car and the nut under the car at the same time. I've got around this on my car by putting a nut between the overdrive mounting and the mounting platform, this only raises the gearbox by about 1/4 inch so causes no problems and it locks the bolt in place inside the car so you only have to worry about doing up or undoing the nuts under the car.
To finish off here's a couple of pictures from SEM at Leatherhead last weekend, I managed to get along to this but not in the Triumph as it was still in pieces!
Turbocharged Sprint Engined Spitfire, this used to be seen regularly at Triumph shows a few years ago and was back out again being used in anger.
