sixtynine Posted December 31, 2020 Report Share Posted December 31, 2020 I have the moss kit and have used the higher boost pulley since day 1, no slippage with a stock type sachs clutch. But I also have the 9 pound fidanza flywheel which probably grips better than a stock flywheel . https://www.nolimitmotorsport.com/prod/FID-172667 Quote Link to post Share on other sites

Clutch judder in my experience is usually caused by the m/s bearing carrier binding on the gearbox nose. Always noticeably on hot dry days in London traffic, some people call it ratcheting. It plagued me for 40 years and I only got rid of it by using a bronze bearing carrier from Revington as used by the original TRs. The difference in clutch operation is very different, its nice and smooth now. I am still looking for a Luke clutch trust bearing as I am told they are the DB! as against the RHP type. Bruce. Yep, a gearbox out job. I might put up with it for a bit longer. A few extra revs as you let the clutch out seems to cure the shudder, if not the cause.

Yes, the gearbox mount was broken when I bought the car and I had it rebuilt and improved. I fitted new engine mounts last year. The shudder has been there since I fitted the new mounts but I will get under and check the box mount again. I just checked the gearbox mount and it is not broken but it does allow the gearbox to move about 1/2" using a bar to lever the box. It could be moving more under engine loads. The mounts are now oil soaked so maybe that is adding to the problem. Edited January 1, 2021 by John McCormack Quote Link to post Share on other sites

Revington who are a cut above the Rimmers and Moss'es went back to the original design and made clutch bearing carriers out of bronze instead of m/s but don't buy Moss'es solution which is made from brass. That to my mind shows their level of engineering. (Brain dead). Another member of our group has done the same as me and his judder has also gone. Bruce Quote Link to post Share on other sites

There was no difference? The top TR Garages here told me what the problem was and they were a 100% right! Bruce. Quote Link to post Share on other sites

Bruce TR Workshop of Lexham Mews would only guarantee their clutch changes if they also fitted their own phosphor bronze release bearing carriers with the other items when repairing TR 5 & 6. That was in the 1980’s. There has been one on my TR 3 with 4 synchro gearbox since then and it works faultlessly. Cheers Peter W Quote Link to post Share on other sites
