Output shaft oil seal

On a CB77, is it possible to replace the output shaft oil-seal without removing the engine?

You don't need to split the cases, just remove the sprocket and pull the old one out. A pair of sheet metal screws threaded into side of the seal will give enough purchase to pull it out. Ease (round off)any sharp edges of the hole in the case with small file so the new seal can start into the hole without peeling the edge off. Drive it in with a deep socket or a length of pvc pipe, a small amount of sealer on the od of the seal would be a good idea.

Mike - many thanks, getting familiar with this motor, the manuals are a little difficult to follow!
