What size crankshaft to order

I now have a need to go ahead with a rebuild. When ordering the engine kits, they ask me which crankshaft I have. Is there an easy way to tell whether I have the one with the 2.0" I.D or 2.015" I.D timing gear without taking it to a machine shop?? .015" is too small to gauge without a micrometer. Just wondering if there is something stamped on the crank somewhere.

The crankshaft looks to be in great condition. I am trying not to have to completely remove the engine as I am having to do this work outside and do not have the equipment to remove the engine. Thanks in advance. Robert

If you want to do this job correctly to insure success. You will need to take the block, head and the crank to an experienced machine shop. The crank will need to be checked for wear and probably will need to be worked. The machinist will take it down and tell you what size bearings to buy after he works it. He値l almost tell you what size thrust washers to get as well. The sleeves need to be pressed out. When the new ones are pressed in they will need to be bored to size. They are re-bored after they are pressed in to insure size and to insure that they are true. Lastly, you値l want him to make sure the head is flat. The kit will come with springs and values.

I壇 go find you a garage to put your girl in; you値l need an engine hoist as well.

Regarding the sleeves (liners), if I buy the kit that includes the pistons, rings and sleeves, aren't they a matched set that will not require reboring?? If not, then I have no choice by taking the block to a machine shop. Lucky me...

After removing the pistons, it looks like this thing has been rebuilt, at least partially, before. The #1 piston is in the best shape (minimal scoring) where the other 3 have what looks to be partial melting of the piston between the top of the piston and the top ring groove. Oddly enough though, the sleeves are in good shape, compared to the pistons. The #1 connecting rod has a different # than all of the rest and the nuts for the rod bolts are 11/16" whereas all of the others are 9/16".

Thanks for all of the fine support everybody is offering. Thanks, Robert
