So I think the threading on the crank case may have shredded from overdoing the torque. Which is alarming because I don't recall ever really pushing the torque.
In any event!
Is it possible the stud is ripping out of the case?
If so, can it be re-threaded slightly largely or do I say screw it and put a new case/motor in?
Thanks in advance.

I def should have enough meat, it's not outright pulling i just can tell because the stud comes out or goes in with the bolt haha. stupid aluminum cases.... if this fails i may just buy a new motor and put it in over the winter.

If you fit an insert, it should be stronger than when new.
If you don't feel comfortable doing it yourself. Any garage should be able to do it for you. For not a lot of money.

I had this happen. No matter how you look at it, it's extra work. If the stud pulling out is one of the two on the stator side of the engine, that is a (not saying easy), not so bad of a fix. If the stud pulling out is one of the two on the variator side of the bike - that is a much bigger job. The right crankcase (stator side) is really quite small and not very difficult to remove and replace. Also the right side 1e40QMB crankcase is easy to find and inexpensive. On the other hand, the left crankcase can be a short case or long case. If he left crankcase needs replacing almost all of the engine has to come out of the old and into the new left case. |
