Have a Briggs & Stratton 10 HP 28A707 Engine. The crankshaft extensioner came out when taking the starter clutch off. Threads looked bad. Bought a new one. Retapped the crankshaft threads, now what needs to be done when replacing the new one.
Thanks for the replies. This is the first one I have ever seen come out. I did loctite it today with red, will wait a few days before I try it. Hope it holds.
