HOME and how to join Forum Open Area General Scott topics Advice please – gearbox or engine problem??? Re: Advice please


Hi Colin, First things first….. Your gearbox cannot have seized up without some damage having occured. The next thing is to disconnect the primary chain and then operate the kickstart lever. The box should turn over perfectly freely if generally O.K. but you have almost certainly got some damage to either the layshaft bush positioned behind the kickstart or to the High gear bush on the end of the mainshaft behind the clutch. If the damage is serious you will probably have an oil leak from either of these two points. The main risk is if one of the bushes has seized onto its shaft and is now turning in its housing and wrecking the gearbox shell or end cover. If it was mine I would have the end cover off the box to investigate. This can be done with the box in-situ. Regards. Brian.
