Hi mate, have checked fork and retaining bolt, all tight, so I am taking gearbox out and trying one I have found in my store, it seems to get all gears, but going to put in with a couple of bolts and try it.
Well still got nowhere with this thread, thanks for your input, but I think Wireman is pointing me in the right way, and is it easy job to change bearing on reverse shaft end, I think the bearing has collapsed allowing cog to partially slip.
Hi mate, have found the bolt that you referred to and it ca be adjusted by loosening the lock nut on it, I have tried adjusting it in many positions but still grinds,
