RE: ASP 21 GOING CRAZY trying to find the propnut size and thread count??? HELP
Mr. Sieminski,
Although in the past, some engine manufacturers had special bearings produced for them (to make the replacement bearings available only from them...), no manufacturer will make his own thread size on the crankshaft...
It can either be a known metric size, or a known imperial size.
People here are reciting the different threads it can be...
Go to your nearest DIY outlet, with the engine. Ask the person responsible for selling bolts and nuts, to determine the thread size of your ASP...
