Ever think of scrapping an entire engine case over a single bolt hole?
For those that don't know, that's one of the oil pump screw holes.

TIG weld
the piece, build it up and then drill and tap new threads if possible. With any luck at all the area is not high stress.
I've found that welding case material is a pita and the end results aren't as good as the original material.
My 850 snapped the electric starter idler gear shaft and although I had it welded and machined it never would hold the torque of the starter again. It broke twice more before I just went with the kick start.

All of my bikes are projects, maybe one day I'll have them running. -
Not too familiar with this area of the motor but the picture seems to show some room behind the broken tang. If welding/tapping will not hold then What about welding it up, drilling it and then installing the oil pump with a bolt and nut with some permanent thread locker?Mike Giroir

Once you un-can a can of worms, the only way to re-can them is with a bigger can.Comment

Yeah, when I crashed and had to have my engine case welded, a local shop did it for me and now plan on using them again. I thought of installing a screw into the threads that are there and let them weld around that, then try to unscrew it afterwards, hopefully the bottom threads of the screw cleaning things up as I bring it out. That seems to be the plan in my head at the moment anyway. If it doesn't thread up well, but there gets to be some "meat" there to screw to, there is plenty of room for a nut/bolt like TADracer mentioned. BUT.. the new aluminum has to stick to what's there.Last edited by trbig; 01-02-2015, 10:32 AM.Try your hardest to be the kind of person your dog thinks you are.
