Lateral play in the cluch shaft - ok or shim?
Hi Everyone
I’m rebuilding my engine botom end (new bearings, oil seals etc are now in there) and I notice that there’s a bit of lateral play in the shaft that the clutch is attached to – if I pull the clutch housing towards me, the whole shaft will shift by approximately 1.5 millimetres.
The looseness is inside the crankcase – I can see the bearings shift sideways in their recess in the crankcase.
Should I reopen and install a shim, or is this looseness ok/normal?
Things to bear in mind:
- I didn’t notice this before (it may have been there or it may not) and there were no shims inside the crankcase when i opened it up
- A spare engine bottom-end that i have also has this same looseness.
- I’ve already put on the camshafts and timing chain (so I’m reluctant to go back in and re-buy new gaskets etc)….but if it needs doing, it needs doing…
Looking forward to your replies!
Cheers,
Pev
Ps – bike is an XT350 1989, but I’m thinking that there are probably some similarities/conventions
