Hi,
I bought a ABSAF BSA years ago with a belt drive SRM clutch (at least pressure plate says SRM) and it is a little grabby,(snatch) during engagement. i have taken it apart and all looks ok. Not sure if i should lube it and if so with what..
thanks, Joe A

Sounds like the clutch stack isn’t being lifted far enough to break any engagement.

The standard plates are designed for running in oil, a dry clutch really needs a different composition of plate

Hi
The clutch disengages fine and worked ok for about a year but then started to get a little grabby as you engage it.
i cleaned and checked all. then lightly resurfaced to be safe and it worked ok for a while but started up again..i was just wondering if anyone had any suggestions or remedies. I have read a few Ducati forums and there is a method of using black lithium grease applied to friction plates heated and then wiped off. a few owners had good luck with this method for extended period. Any additional suggestions or thoughts ? I figured there may be a few using dry clutches that may have encountered the same problem and rectified it. thanks, Joe

Have the ends of the pushrod been annealed properly? Sounds like one end is mushrooming giving you your problem.

This is the clutch that is installed not sure what make it actually is but it does not have grooves for friction plates like most..

Tony Hayward used to sell clutch baskets like that with belt drive kits.

If you have the same Surflex clutch plates that came with mine, don’t let oil get onto them.

I haven’t had to bother Tony for years, but a phone call was the way to deal with him.

The SRM pressure plate has changed in design now but the first ones which were the same as the Devimead units were cast and not machined from billet. I had all 3, the 2 cast ones keep requiring adjustment... then the threads popped. The billet one was no problem for all the time I used it.

Like TT says. It looks like the Hayward kit I have.... Which I would never use.
