Help

Just discovered play between the clutch centre and basket on my B40. How much is acceptable, if any ?

Might new roller bearings help, or is it time for (gulp) new clutch assembly.

Any info appreaciated.

Ross. You have all the luck don't you!

I would imagine any noticeable play is not ideal.

Wayne....

Got a new clutch basket and centre + roller bearings. Still exactly the same (old basket was worn from friction plates anyway)

Was looking at Rupert Ratios book again and it mentions a thrust washer between drum and flange. Mine has never had one,

and looking for one on the trialsbits site it's not listed.

Any suggestions for a suppier ?

Thanks

C & D autos have bi-metalic (bronze/steel) thrust washer @ 6 thou, but it isn't listed for this model. Is this slight rock really a problem ?

Was the clutch slipping or doing anything odd Ross?

Hi BJ

No problems at all, just noticed the movement while checking the primary chain tension.

not a beeza expert.. but the bearing comes into play when the clutch is pulled in with the engine running... so never come under load, a single row bearing will always have "play". not sure about the thrust washer tho.

Trust washer is available, but not sure if required, as you say. Under load the plates lock up and all forces are transmitted through the gear box shaft, I hope.

Anybody (Wayne) wish to confirm.

I have the same play on my B40, it's not a problem. I don't have a thrust washer there either. Only problem I can think of is if the play is excessive then the primary chain may wear the edge off the basket teeth.
