earckens Posted August 4, 2017 Report Share Posted August 4, 2017 In a different topic ( http://www.tr-register.co.uk/forums/index.php?/topic/62972-grease-nipple-at-clutch-cable/) it came to the attention of RAHTR4 that the clutch hydraulic cylinder may not be fitted on a proper plate. I checked and found that the cylinder is tightly fitted but that the push rod may not actually be alligned correctly. I included some pictures for your reference, please have a look and let me know what needs to be changed? Thanks! Erik Quote Link to post Share on other sites

TR NIALL Posted August 4, 2017 Report Share Posted August 4, 2017 Is the Slave Cylinder leaking fluid? Quote Link to post Share on other sites

RogerH Posted August 4, 2017 Report Share Posted August 4, 2017 Hi Erik, as you have noted the rod is not in a straight line between cylinder and drop arm. The cylinder is slightly outboard of the car centre line. This is normal - but not good. It adds to the force required to operate (only a little bit). I made a new plate that brought the cylinder in towards the gearbox. How handy are you at fettling. Roger Quote Link to post Share on other sites

Roger I have fairly good mechanical skills, and tools too (especially the newly installed lifting bridge ), but no TR4 experience at all. My first job will be exchanging a rotten gaiter on the steering rack (today). Edited August 4, 2017 by earckens Quote Link to post Share on other sites
Richardtr3a Posted August 4, 2017 Report Share Posted August 4, 2017 I have a similar problem. I followed advice and used the centre hole which put my operating rod at an angle. This damaged the slave lining in a short mileage. I had a new slave fitted which failed after 1 hour. Finally I had my original relined in stainless steel by Past Parts Ltd and it is better than new. However I am now using the lower hole, for a straight run, and I am having problems adjusting the clutch rod. Maybe there are variations in these mounting plates?? Richard & H.

BlueTR3A-5EKT Posted August 4, 2017 Report Share Posted August 4, 2017 (edited) TR2-3-4 with spring type clutch with a return spring fitted between the mounting plate (small drill hole in lower edge) and the clevis pin (through attachment plate) Clutch push rod is then adjusted as per instruction manual, to give a set clearance. is it...Extend till it touches then back more than one turn, less than two, then lock off with nut.? TR4A onwards had a diaphragm clutch and no fitted return spring or adjustable clutch slave push rod. No adjustment is needed as the hydraulics take care of the adjustment. Oddly the TR spares world has started selling adjustable clutch slave push rods for these self adjusting systems, aimed at TR5/6 owners, who probably have worn out clevis pins and egg shaped clevis pin holes in their clutch pedal/push rods etc. - Does it make the clutch work better ?... not in my mind.

Lebro Posted August 4, 2017 Report Share Posted August 4, 2017 I think the point of having return springs is to reduce wear on the release bearing Bob. Quote Link to post Share on other sites
AlanG Posted August 4, 2017 Report Share Posted August 4, 2017 I thought the adjustable push rod was fitted to 4A's. Certainly the PB shows it. Alan. Quote Link to post Share on other sites
