I wonder on this also... as the two sides of my (not so hot in shape) crank. and my other junk one are differant from side to side..
On mine the flywheel side is smaller by .0003 or so...
jonny500:
i have split 100s of engines and i never knew that cranks are different sizes on each end. that info came from a well respected motor engineer with alot of years under his belt, i have no reason to disbelieve. and it does make sense as when i split a case more often than not 1 bear stays on the crank. unfortunatly i dont have a good flywheel side to measure

IN the cylmer it say (if the right main bearing came off with the crankshaft remove with bearing puller)page 197
i asume by this there not expecting the left side (flywheel side) to be as tight
i too have a crank with the flywheel side worn,right side ok
I personal would rather do both side to the tighter clearances [ maybe press the bearings on the crank,at least then i know it would have little chance of wearing again

dave916, it was chris applebee that told me this. i think if you do that it will cause some problems whemn the cases are put together and pulled apart, maybe
