While I am on a roll, Another question. I think this has been covered in the past but cannot remember the details.

Decades ago I put in a Triumph 2000/2500 gearbox. There was an issue in that the splines for the clutch plate were different on the 2000. You had to either swap the gearbox mainshaft over and use the TR clutch, or find another solution.

I used an Isuzu truck clutch plate from memory as I had kept the 2000 gearbox mainshaft and the splines fitted. I also seem to remember that the plate was a slightly smaller diameter than it should have been. It is starting to slip, and I will have to pull it out soon.

I would like to hear other experiences of how people have mated the 2000/2500 splined mainshaft to the TR clutch.

I have used a saloon plate with no issues. I have broken a gearbox with spirited driving but the clutch was ok.
The 2.5pi saloon puts out more power than the TR

Hi Peter
From memory, I thought the TR pressure plate and the 2000 clutch plate were incompatible. Is my old and fading memory wrong on this?

You may be able to use a Izuzu clutch plate that fits the C240 engine P/N 5312400190. This is a fork lift unit.
Best solution is to use a 2500 clutch kit. (plate,cover, and bearing) Exedy kit available from Ebay at $265.00. Redrill flywheel and use the original 2500 bearing carrier. Do not use the clutch return spring.

I think I have the Izusu is the one I have. From memory, it was about 3/4 of an inch smaller diameter than the pressure plate. It was never the optimal solution. I only did it because of time pressure when I put the 2000 box in and had to get the car back on the road straight away.

I looked on ebay but am not sure of the kit you mentioned. Closest was Exedy Clutch Kit For TRIUMPH 2000 2500 DOLOMITE GT6 VITESSE Sedan Coupe[/url] which is $280.15
Is that the one you were talking about?

I just removed one of those plates from a TR3A that was fitted with a Ford pressure plate. I thought it was the correct diam when I used one some years ago with a Ford PP. While it fitted the Ford plate it is in fact 9.5" (240mm) diam so a bit too big for the TR plate.
The Exedy kit is TRK-6116.
I got the one I just fitted up for Bill Newling from Automotive Superstore ($263.59). Item 253316569422 on ebay.

You will need an unmodified 2500 thrust bearing carrier.

The kit I mentioned seems to have the thrust bearing carrier. Not sure what you mean about "unmodified". Maybe I need to go back to the manufacturer to check part numbers.

I think you will find that the picture shown is just a representative one and not the actual one. The bearing shown is not for a Triumph. The kit P/no is correct though. The kit I got came from Sydney and only took 2 days. Just up the road from me actually.
When I say unmodified, I meant not machined for a different bearing such as for a Ford pressure plate. The straight Triumph 2000/2500 unit is fine.

I suspect the real problem may be getting my hands on a thrust bearing carrier. I have been searching for about an hour without success. Rimmer Bros in the UK expect to have them in stock end August for 88 pounds.

Try David Clark at 28 Mary Parade. Rydalmere. Ph. 02 96383941. David has a Triumph repair business and is a good bet.
Also the 2500 carrier is a smaller diam as is the extension it slides on. Did you replace the extension when you fitted the box, if so you will need one of those as well. The TR and 2500 extensions are interchangeable.
Both of these are the same on both overdrive and non overdrive boxes.
