April 24, 201016 yr All sorts of thread form helicoils available here: http://www.uni-thread.com/, click on 'Helicoil Inserts & Taps' on the left hand side of the page.
April 24, 201016 yr Helicoiling is easy, if you can re-build a motor, it's really really really easy. If you go to an engineering shop, for some reason it is very difficult and expensive The trouble (in my experience) with Cubs is that owners replace the original cross head machine screws with Allen head machine screws, then apply a lot more torque than the threads can take - hence the stripped threads. I'm not sure which cover you mean, but I'm guessing its the RH inner cover over the gearbox / oil pump / Camshaft drive. That one is held on by four 1/4" BSF bolts of varying lengths. A 1/4" BSF helicoil kit including the correct oversize drill tap and 20 inserts is yours for around Edited April 24, 201016 yr by GII
