Clutch plates

<< < (5/22) > >>

Trigger:
The shorter spring was used in the 750K0, K1, and some early K2's. Then it was superseded to the longer spring with a smaller diameter coil. Early spring at the top later at the bottom in the picture. The longer one just means a smoother clutch. [ Guests cannot view attachments ]

Trigger:
spend a bit of time putting together a K2 clutch so you can see the stack measurements. Much easier to build the clutch up on the bench and then put it in the engine. You should end up with a stack at 37mm
You can pull the clutch together using washers on the springs and then you can see what is going on.

One thing i forgot to ask, what was wrong with your clutch in the first place ?

Do you have a thin washer behind the basket ? and the thick keyed washer in front of the basket ?

Pauarc:
The clutch drag a bit before and gear change was clunky old plates were hard not any better with new plates no thin washer that I can remember but there was a thick washer
