I am closing up my TY and I've run across an issue with the pressure plate. The clutch plates themselves are new and worked well when I put the bike away some 11 years ago...at least I can't remember any issues. Anyhow I was just in the process of tightening the clutch springs, washers and retaining bolts. My manual said to tighten them to 5-7 ft. lbs. I tried that and I promptly screwed all five bolts down tight. They bottomed before I could get a reading on the torque wrench. None of this seems right to me.

The springs do not look like they could put up enough resistance to hold 5-7 lb. ft. The springs just do not look or feel that strong.

Am I missing something? For example, I could shorten the retaining bolts and try again to see if that torque is available before the springs bind up on themselves. That doesn't seem right because they are the screws that the bike came with.

Help....Please

That torque setting is only to stop them from unscrewing. The screws are intended to be bottomed out.

This is correct, no difference on a modern bike, prolly M5 thread.

Thank you very much for your patience with me. The light finally went on late last night. Probably the biggest "give away" was the fact that the torque setting was the same as for the bolts which hold the side cases on.

Anyhow, I have been used to "adjusting" the tension on these bolts to achieve a uniform release of the clutch plates...like on one of my old BSA's which required that the bolts be safety wired once the appropriate tension was reached. On my Bultaco, you are instructed to look down at the retaining bolts to insure that the clutch plate is parallel with the engine cases...Now I get it. Just tighten them up

Thanks again...
