Drill And Re-Threading Gearbox Crossmemberthreads.

[hnr32-25T]

Dropped the box and found 2 helicoils in the crossmember right hand side threads. i dont think i can just run the original size tap through because some has helicoiled it.

The crossmember has rubber bushes which the bolts fits through, so i was thinking drill the threads out to the next size and re thread and then just drill the bushes out to the same size? would this work.

I have done the exact thing. Used 12 mm high tensile bolts and rethreaded to the right thread. Good as new.

champion. im guessing the original bolt x thread pitch was a 10x 1.25 or 10x 1.5. will take out one bolt from the left side and double check the thread, get the same thread in a 12mm tap and drill away. cheers
