I have four bolts that I think are for my flywheel to crankshaft. They are 3/8" diameter, fine thread, 1.17" length overall with 1/4" bare shank and the head is larger than normal (.560") at .625" across the flats. Are these the correct bolts and is it safe to reuse them? They look totally undamaged. Thanks and have a good day!

John

Sounds right (but I don't have the specific measurements handy).

I've always reused them, no problems. However, don't reuse the lock tabs. Either replace the tabs every time, or use Loctite instead of tabs (I use Loctite). If you use Loctite, double-check that the tips of the bolts don't protrude through the crankshaft flange far enough to hit anything.

As a quick double-check for any stretch; you can spin a new nut down the threads. It should spin easily all the way. If it binds before reaching the end, the threads may be distorted.
