[AJD] crankshaft bearing replacement

[Lyle Myles]

If Snap On still has the tools they use to be able to turn the crank and
mains without pulling the engine. This has been several years ago when I was
racing and had one on hand when I spun a bearing and did not have time to
pull the engine.

given each and every one of us to enjoy and behold!

Subject: [AJD] crankshaft bearing replacement

I purchased a 620 a few years ago with a siezed engine.  My investigation 
showed that gasoline in the oil caused a loss of lubrication and one spun 
bearing on the main crankshaft.  The engine turns perfectly by hand or 
starter but obviously needs a bearing replacement.

Is it possible or practical to remove the flywheel, main bearing covers, R&R

the main bearings on the left side only and reassemble?  Or do I need to 
pull the whole crankshaft? This is not a project for the coming weekend but 
am thinking of a project for the coming winter.

Thanks,  Kreig
