Hi guys, I am all new to this forum but I have spent a lot of time reading the various posts and realized that if you need som help this is the place to go.
Hopefully someone on this forum can give me hand
I am putting my 1969 Commando back on the road after after 32 years in the shed. I knew it was going to be a daunting task, but I never expected that virtually every item on the bike would require a fair amount of TLC.
From what I can recall from my last ride, 32 years ago, the gearbox was OK and no real problems. Looking at it today there is a play of approximatly 1 mm (0.5 mm in each direction) between the main shaft and the sleve gear shaft (where the gear box sprocket resides).
I assume that it is the sleve gear bushes that are worn.
I can feel no play at all between the sleve gear bush and the oil seal.
Is 1 mm play acceptable? If I can avoid pulling the gearbox apart, that of course would be a bonus.
Also, as can be seen from the picture, the five outer threads on the mainshaft are worn down to about 50% of their original depth. The remaining threads are OK. Is this a cause for concern?
I am afraid that there will be many more questions to follow as the restoration progresses.
