Hi guys
Can anyone tell me which way round does the engine sprocket go on my bsa a65 1967
Anti-clockwise?
The way that makes it line up with the clutch sprocket.
Good morning Spike,
If you hold the sprocket so that flatter side is towards the engine it will go one so that the teeth are quite close to the crank case with the spacer on first to sit in the seal. If you have never refitted the primary before then the sprocket, chain and clutch go on at the same time. Also, you need to make sure that the clutch and front sprocket are exactly in line so that the chain runs straight. If needed, shims are put between the back of the sprocket and the spacer to get this right.
Dave.
