I have pulled apart my HP 49 that has been sitting idle for well over 15 years. I've been reading back posts to this forum and realize there have been different iterations of the engine with regard to shims and washers being either included or not.
Right now, I have a small issue as to the correct way to pull the two main ball bearings off the crankshaft. It appears the spinner backing drive collar needs to be pressed off after which the bearings can be pressed off. Any one have disassembly instructions and also an exploded parts list so that I can order the correct replacement parts?
