Washer question, flywheel collar, clutch.
 

Ok still trying to get an understanding on this. When setting up the flywheel collar I have three different washers to place behind the flywheel collar (0.2, 0.3, 0.5mm are the sizes)..What am I trying to achieve when choosing the correct washer? It says “proper clutch bell end play” but I’m not quiet sure what this mean.

I use the .5, but use shims in front of the clutch nut and in front of the outer clutch bearing for clutch bell end play and positioning.

Those washers (shims) are meant to keep the various parts from rubbing against each other. So if the flywheel rubs against the crankcase, you put a shim behind the flywheel collar (collet) to space it away from the crankcase just enough so it doesn't rub. Same goes for the clutch bell and flywheel. If the CB rubs on the flywheel, add enough shims so the CB doesn't rub on the wheel. And finally, you add shims onto the very end to adjust the endplay. Add enough shims so that the CB only slides about .5mm or so along the crankshaft.

Make sense at all?

Makes sense but I didn’t know that you can use the other shims in front of the fly wheel nut.

I use the big washers behind the collet to 1) make sure the flywheel can clear the crankcase & carb. 2) to line up the flywheel with the opening in the chassis for the starterbox 3) to make sure the clutchbell lines up with the spur gear.

I use the small washers behind the inner clutch bell bearing to make sure the bell does not rub on the flywheel, and does not ride on the front face of the clutch shoes. Also have to make sure the clutch shoes are covered by the bell.

I then use the small washers on the outside bearing to adjust the play.

I hope this makes sense?

Its not as hard as it may sound. Really!

Ok so I used the .5 shim behind the collet. However, it seems to me that the clutch bell has a lot of play. Is this ok? If so would it be ok to add another shim so that there are two washers behind the collet?
