I ordered a manual, but am waiting for it. Can anybody tell me what the diameter of the crankshaft at the main bearings is when its new? I am trying to figure out how worn they are.

If I were you, I would take that shaft to a well known machine shop that's known for doing good maching to have it measured and make sure that it isn't worn egg-shaped. They can mike it very quickly and tell you if the shaft still measures
standard or is worn undersize. It may just need polishing if no maching is required. They can also supply you with undersize bearings if it is needed.

You should have that engine block degreased and have new cam bearings installed and inspect and measure that camshaft for wear. This is so you have good oil pressure when the engine is reassembled. Hal

I was going to give those to you on the other posting, but I'm not sure which one it is from my manual. I'll give you what I think it is 2.4975-
2.4985". You can tell from your micrometer reading. It may be 2.5475-2.5485". My manual recommends 53 ft-lbs torque on the rods and 100
on the mains. Hal
