LH Crankcase Cover

<< < (2/2)

DerekB:
Thank you for all the excellent advice.  Like I said previously, there were maybe 5-6 small broken o-rings that fell out of the cover when I removed it.  Are these for the grooves that are on the push rod?  Or somewhere else?  I currently did not replace any of them since I was unaware of where they came from.  My maintenance manual does not spec them out anywhere.

Bryanj:
Only O rings inside that cover are behind the oil pump and cannot fall out, also they are 15mm.

Sounds like somebody has put them in there to cover up a problem. As oddjob said check the ball bearing and pushrod, adjustment procedure is in the manual

DerekB:
I disassembled the entire assembly today and gave it a good cleaning and new grease.  Reassembled and adjustment and the clutch lever now works.  The lever has always been fairly tight to squeeze and I figured out why when reassembling the parts.  I don't think all the parts are stock inside the cover for the clutch actuation.  I noticed that while squeezing the clutch lever, when the internal part is rotating it hits on the sheetmetal bracket inside making the clutch lever hard to compress.  I didn't modify the bracket yet to give clearance, but its on the list now.

Thanks again to for the help!

Derek

Bryanj:
That sheet metal contraption is to stop excess damage if the chain breaks but can get bent and cause problems
