#22 How can I tell "Coarse" from "Fine" threads on my engine shaft.

One of the best ways to get this type of technical information is to refer to the Manufacturers Publications that came with the engine. They will usually tell you what the crankshaft thread is, but not always.

If this does not work out, or you do not have the publication to look at, try going to "Question #  16".  We have covered a lot of information on this subject and it should help you with this problem.  If you do not find the answer you are looking for, please call or E-Mail us and we will try to help you.
