JohnRoberts Posted December 12, 2018 Report Share Posted December 12, 2018 (edited) Hi Guys At the moment I have got the body off, and having the chassis repaired and strengthened. While I have engine and gearbox out and separate. Looking at improving the clutch release mechanism. Has anybody got experience of direct acting angular release hydraulic cylinder. I can see 2 of the regular suppliers offer such a system, at considerable cost. Regards JohnR Edited December 12, 2018 by JohnRoberts Quote Link to post Share on other sites
HSM Posted December 13, 2018 Report Share Posted December 13, 2018 Concentric release bearings include the hydraulic slave cylinder, when they leak its a gearbox off job. Harvey S. Maitland Quote Link to post Share on other sites
TriumphV8 Posted December 13, 2018 Report Share Posted December 13, 2018 We are right now working on that project. Will fit three TR6 with these system. Expect less pedal forces due to less friction and do not see leaking problems. All modern cars use that and they last more than ten years. Quote Link to post Share on other sites
harrytr5 Posted December 13, 2018 Report Share Posted December 13, 2018 My Tilton annular has been in service since 2004 in my TR5 and works really well. Needs careful setting up though Regards Harry Quote Link to post Share on other sites
JohnRoberts Posted December 13, 2018 Author Report Share Posted December 13, 2018 Hi Harry Thanks for the reply. Can you remember which model Tilton and where you obtained it. Many Thanks JohnR Quote Link to post Share on other sites
Keith66 Posted December 13, 2018 Report Share Posted December 13, 2018 Hi All As with all of these upgrades there can be good and bad. Modern equipment in modern cars is way more reliable that most things on our cars and can bring benefits. But its all to do with the quality of the engineering concept, parts and execution when fitting modern parts or systems to old cars. A modern concentric release bearing including the hydraulic slave cylinder in the bell housing is neater more space efficient and lighter and smoother. Just not automatically better, just ask the owners of many a Rover 75, MG Zt, or Freelander where premature failure is not uncommon due to poor parts quality, poor fitting and set up. And of course if there is a problem it is GB out. So you pay's your money and makes your choice. Just enjoy the TR with all its foibles and downsides.

deryckp Posted December 13, 2018 Report Share Posted December 13, 2018 Hi John, I have had a Tilton annular clutch kit on my 6 for about 9 years now. Works well, and in conjunction with a Laycock cover gives a light feel. Supplied by Racetorations and fitted it myself. There was some measuring up to do in order to arrive at the correct dimension to machine the pedestal to, but nothing that a competent home mechanic can't do. At the time they were under 400 quid, but I think they're a lot dearer now. Cheers, Deryck Quote Link to post Share on other sites
RogerH Posted December 13, 2018 Report Share Posted December 13, 2018 Hi John, the concentric slave cy is very tempting and I've considered one on the 4A, but!! The original set up is pretty good. Support the taper pin with another bolt/pin Double up on the bushes, Fit a decent bearing and carrier and it should last many years. If you are concerned with a heavy pedal consider a servo as per the brakes. Roger Quote Link to post Share on other sites
JohnRoberts Posted December 13, 2018 Author Report Share Posted December 13, 2018 Hi Roger Am not concerned about the force required to operate. but a smoother operation. The carrier is steel, bearing RHP. would phos. bronze be a better solution. Also noticed the clutch forks show a certain amount of wear. Regards JohnR Quote Link to post Share on other sites
RogerH Posted December 13, 2018 Report Share Posted December 13, 2018 Hi John, when you say you want it smoother - does it judder or snatch when you lift the peddle up? If that is the case then you may well have an alignment problem. The GB case should be doweled to the back of the engine to ensure good alignment. (two special bolts required on the TR6) many people say that the Phozzy bearing carrier is better than steel. I also thought that. But I have found this is not necessarily true. I was getting clutch judder (lifting the peddle) with a Phozzy carrier. When I sorted the alignment I went over to a very nice TRShop steel carrier and it works very nicely indeed.

Tim D. Posted December 13, 2018 Report Share Posted December 13, 2018 Always up for an upgrade but the standard system seems pretty good if you sort the fulcrum pin issue. One observation however was that getting a clutch kit from Trgb seemed to reduce the effort somewhat. It is actually lighter than my modern and still handles the torque from the supercharger. My sister managed it happily for the whole of the rbrr. Tim Quote Link to post Share on other sites

Roger Roger, are you certain you did not have a Moss special made from brass? Do they know the difference yet? As they seemed very puzzled when I rejected their's Bruce.

RogerH Posted December 13, 2018 Report Share Posted December 13, 2018 Hi Bruce, I've had two of their soft brass carriers. They had me puzzled when the spigots on the fork would dig in rather quickly. The TRShop steel carrier is perfect - honest. Roger Quote Link to post Share on other sites

They need to be made out of marine bronze? Bruce. Quote Link to post Share on other sites
RogerH Posted December 13, 2018 Report Share Posted December 13, 2018 Hi Bruce, good question. It was mentioned to them but I must admit I have not followed it up. I understand that Revington do the correct material. I will look into it early in the new year. Roger Quote Link to post Share on other sites
JohnRoberts Posted December 13, 2018 Author Report Share Posted December 13, 2018 Hi Roger Sorry to be so slow at replying, had to go out. does not judder as much as feel notchy up and down. will investigate if the fitted 3/8 unf bolts were used. regards JohnR Quote Link to post Share on other sites
jerrytr5 Posted December 13, 2018 Report Share Posted December 13, 2018 As others have said, nothing wrong with the standard system as long as the cross shaft taper pin a) fits properly & b) is supplemented with a secondary bolt. Jerry Quote Link to post Share on other sites

Waldi Posted December 14, 2018 Report Share Posted December 14, 2018 If the bearing carrier has a sharp edge, it may stick on the center piece. It is best rounded, you can test it by hand when moving the clutch shaft and tilting the carrier. Waldi Quote Link to post Share on other sites

Roger I am using the Revington one, not cheap, no problems so far after 18 months and 5K miles and plenty of London traffic crawling! Stickie clutch has gone from day one when first used! Bruce.
