I would like to repair/ replace the gear box myself. How do I proceed ? Drawings or pictures available anywhere? I think, I can get the parts. I am not a mechanic, but I have a good set of tools and have taken a VW transmission apart once and changed the synchro rings....
Anybody done that job and can help?

If not possible to repair, Is there a way to lock the gear box in forward to get home???

Thanks,
Neal
I'm haveing the same problem as you With the transmission (gearbox) model KBW-10 mounted on an old 1979 model yanmar 20QM20 motor. Where did you get the gearbox manual and how did you solve your problem? In advance tks from Norway.
