Fitted my spare and made it 300 meters until the same thing happened. Pulled the gearbox to bits and found the thrust being put onto the input shaft via heicoil (spelling?) cut gears was popping a large circlip off that held the gear in place on its spline. Tried to get a larger/stronger circlip but no luck so I ended up welding the gear in place with the tig and have never had a problem again. From what I could figure out the gear and shaft were made from 2 bits for ease of manufacturing and not for assembly so there is no issues with using the hot glue gun to solve this issue!
Hope this helps mate.

Yeah sorry gearbox/transfer, if you have metal chunks coming out of the bung then I fear you may have done a little more damage. Take care when you are pulling the chain drive out, it can be a bit of an ass but if its all lined up and pulled out square its easy.
Cheers
