kickstart spring not fitting into kick start shaft hole.

Have fitted the roller bearing conversion for the lay shaft and after shimming the kick start shaft with .040" of shim (with the bore of shims clearing the shaft to fit flush against the kick start boss), the kick start spring does not want to fit into the hole on the shaft., all the gears seem to be changing fine, and i have correct end float !. Any ideas ??

Pete,

Not 100% clear what the issue is, but would it be the case that the hole in the kickstart shaft is now too close to the inner cover and the spring stack is now too wide to get the tang of the spring to locate?

I fitted a roller layshaft bearing and after shimming it up I found my RGM kickstart would no longer fit the splines due to the shaft no longer protruding far enough - I couldn't get the pinch-bolt through as it was fouling the groove in the shaft while the kick start was hard up against the outer cover.

One possible solution would be to get shims to fit between the kickstart shaft and the layshaft, rather than between the kickstart shaft and the inner cover, as per 'normal' practice.

The other alternative is to fit the Hemmings bearing, which is what I ended up doing. This maintains the original design aim of providing the positive location for the layshaft.

Assuming that's your problem, of course :wink:

Andy,

Thank's for the reply, have just edited the message , it should have read "spring " not shim. Yes what you are saying makes sense, can get the spring to go in but it is really compressed when i do. Might try the shimming the other way as you mentioned.

Cheers .

I'd of tried leaving the inner and outer gaskets out - and have- so spoiled on no shims several trannys now.

I guessed right for once! :wink:

I talked to Mick Hemmings on this, and ended up removing the roller in favour of one of these high-capacity ball-races:
The fibre cage gets over the problem of the original shedding the steel cage and allowing the balls to drop, but still provides the positive layshaft location needed.
