Triumph TR3 - clutch slave cylinder

Hi all:
Does anyone out there have any experience in replacing the clutch slave cyl.[TR-2, early 3] with a TR-6 cylinder? The Moss catalog says that this can be done but that it is "not totally satisfactory".I realise that the pushrod needs to be modified, no problem there, but I wonder about other potential problens, ie return spring. In my TR-2 the spring is oriented opposite to that in my "6".

Any/all comments GREATLY appreciated.

Thanks in advance.

Dale.

Dale-The difference in the return spring shouldn't be a problem. Triumph eliminated the external return spring and adj. pushrod on the TR6 to make the clutch self adjusting. I reversed the procedure on my TR6 because the TO was wearing a groove in the pressure plate from constant contact. Have you considered having your original slave cyl re-sleeved? It might be the easiest/cheaper route.

Dale-The change in the return spring arrangement shouldn't be a problem. Triumph eliminated the external return spring and adj. pushrod to make the clutch self-adjusting on the TR6. I reversed the procedure on my '6 because of a groove worn in the pressure plate by the T/O bearing. If you still have the original slave cyl., perhaps having it re-sleeved might be the easier/cheaper route to go.

Whoops-Sorry for the double posting.

Thanks for the comments BTP.......re-sleeving the cyinder is no problem here in the Toronto area, however the thread areas, both bleed and pressure in, are quite dodgy. They are both weeping to the point that "something" has to be done! I have done heli-coils a few times, but never in hydraulic applications.I also tried the spring reversal thing on my "6", but with negative results, ie lots of poor/zero clutch release situations. I went back to original configuration putting up with some wear on the clutch pressure plate springs.

Any advice re heli-coils on hydraulic cylinders?

Thanks again.

Hello again BTP......

Just had a look at my '6 clutch slave cylinder.......and it appears that I must eat my words, NO external return spring!! My previous one, a '73, DID have one however, perhaps in error. Anyway......a seniors moment now corrected.

Thanks.

Dale-I don't think a helicoil alone will solve your problem. If my senior memory is correct, the seal is formed by the conical seat at the bottom of the hole and not by the threads. In redrilling for a helicoil, it is a crap shoot as to the hole being concentric with the seat. I had a similar problem with a bleeder screw on the caliper. I was able to save the caliper by making drilling&tapping the caliper for the next larger size, then making a fitting that contained the seat-probably more trouble than its worth. You might try cleaning up the threads with a tap, preferably a bottom tap. Good luck.

Hi Berry.

Thanks for the comments re helicoiling in hydraulic cylinders,like you say, a bit of a crap shoot.

On to a different tactic......does anyone out there have a clutch slave cylinder [TR-2/early TR-3] that is surplus to their needs AND that I could buy/beg/borrow/steal? My preference would be #1, but I AM getting a bit desperate!

Thanks in advance.

Dale.
