Yeah, this sounds like a stupid question, and I've had plenty of experience rebuilding engines. Here's my problem. I've got a Ferguson TO35 engine torn apart and am trying to do an "in-frame" motor job. This all began because a sleeve was leaking coolant into the oil pan.
Engine is the Continental Z134 gas. So, I pulled the pistons and rods out and the rod bearings are all marked .020. So, that's an easy one - .020" undersize bearings. But, the mains have no such numbers. Just FM2227 SB. So, I assume FM is for Federal Mogul. I can't find a listing for that number in any database. I had originally thought that maybe the "SB" stood for standard bearing?" But, now, I'm not sure. Bearings looked good and I was just going to reuse them - so it didn't matter. But, just checked and they've got .0035" clearance (too much). So now I want new ones and can't figure if they're standard or some undersize that is NOT stamped on the bearing. I can't get a mike onto the crank journal while it's still in the tractor. I did attempt a crude measurement with calipers and tape measure and with this very poor measurement - the crank journal seems to be around 1/32" smaller then standard. That could easily be .020" or .030" under.
So, at this point, I have no idea what bearings go get. Anybody ever come across an undersize main bearing that was not marked undersize?
