Thanks for all replies Pete

Something that is often not checked is primary chain alignment and this can get several mm out depending on how far the clutch basket goes onto the mainshaft as the inner edge of the basket spline gets worn and eventually the basket starts to scrape on the oil seal studs. This is where the circlip comes into play holding the basket in a set position, then adjust the engine sprocket to suit the clutch sprocket

Norm that what our hostes spacer does and why i want to fit it.As i say i do not have a lathe and i thought somebody might have a figure to work to as its a bit of a pain having to fit the clutch etc,try the aligment etc strip it back down take the clutch across town get a bit more taken out and repeat cheers pete

i thought the solution was clear with what was explained.



take the primary chain of, put the hardend spacer on the shaft.(be sure there ar no protrusions from the original steel on the back of the clutch center)

put the clutch center back, put the steel ruller on the clutch center sprocket.

measure the distance at the crank sprocket.



then you will have the distance that will have to be machined.



dont forget to subtract the thickness of the hardend spacer from you measurement.

Obviously the ones I have come up against have not been hardened and have become locked solid on the shaft and I can't get them back past the circlip slot and in a couple of cases I have had to get in there with a die ginder and carefully cut the spacer so I can remove the inner primary. Just my two bob
