Good morning all! Have just sent the same question to Bob Newby but thought somebody else out there may have an answer.
The clutch is mounted on the inner gearbox shaft that runs in a bronze bushing in the outer shaft - to which the gearbox sprocket is fitted.
I was thinking that there is probably going to be gearbox oil seeping out between the shafts and then smearing the clutch/belt.
Any ideas on how this can be prevented?
