How do you remove a damaged Tranny Chain Shaft

[ManImSweaten]

Ive opened up the transmission and the bolt snapped at the 4th sprocket just before the threaded end.

I see the nut on the clutch bell side but cant use any tool i own it seems to grip the chain shaft to loosen.

I'm not a four stroke guy but welcome to the forum, if you can post a picture maybe someone will have a suggestion.

I remove that nut with a small milwaukee impact wrench.
The bell is also threaded to the shaft.

Some of the screws holding the tranny case got stripped out by the fool with an impact on philip screws, but I found a great way to deal with that situation.....if you have air tools.

In the end I found a much easier way to straighten the jackshaft without pulling the tranny apart.
The shaft seems to be made from cheddar cheese and bends easily in a vice.
I managed to remove the wobble from the bell.

For what it's worth, I hate those things, had one on my second bike and had several random issues. Replaced with the 5G belt-driven one and haven't had any issues yet. Although both that I have were the single chain version, not sure if the double chain is significantly better. Good Luck.
