OK, in changing shocks, somehow the left stud on the swingarm nearly stripped. Anyone have a fix for this? It is on a GT500. Thanks.

Can it be chased with a die and work again or is it too far gone.
Two strokes, its just that simple.

Most of the threads are gone, just enough to hold the nut if I don't try to tighten. I am thinking of trying to re-thread at the next size smaller or have a new stud made. Getting the old one off does not look like an easy task. After all these years and bikes, I know this has happened to lots of people before. So maybe there is a good method for repair out there?? Please???

The metal on the GT750 swing arm is a bit harder for the studs than normal steel so they dont strip as easily. The ones on the 76 Buffalo i have were damaged a bit by the PO but i was able to save them by chasing the threads.
For the one on the arm you have could cut off and drill out the old stud itself and have a new one made and tacked into place.
However it might just be easier and cheaper to locate another swingarm and refurbish that instead.

Hey,


I had this drama with a Katana I had a few years back - completely stripped shock mount threads...

The fix for me was to cut the threaded part of the stud off altogether, and drill and tap the centre of the remainder of the shock mount 'stud' to accept an 8 (or 6) x 30mm socket-head bolt and spring washer.

It doesn't look stock, but it works quite well - in fact it is the method of choice for myriad other marques.


Good luck
Paul
