JD B-Flywheel play

Looking at buying my first old tractor to fix up. It is a '42 JD B hand start and seems in good shape. But the flywheel has about a 1/4" of sideplay. I was told by the owner that this can be easily removed by adding shims. Is this true or is this a sign of more serious internal problems?

Otherwise, no oil leaks, good compression, good paint and sheet metal and stored in a shed for the past 15 years that the owner has had it. He's asking $1500.

Any thoughts are appreciated.

I know my original question has moved way down on the list and won't be seen by many, but I want to extend a big thanks to all who replied.

I believe this tractor has my name on it. And the responses didn't scare me away. You guys are a great help!

I wasn't sure from your post whether the flywheel itself was moving on the crankshaft or if the entire crank is moving with flywheel staying in same spot on the crank. If the flywheel is sliding on the shaft, you have a problem that needs some help before you tear something or someone up worse. I would think you ought to take the flywheel off and check your crank splines. If your crank is ok and flywheel is not cracked, then put it back on and tighten it down more to see if that will stop the sliding. If the whole crank is moving flywheel is tight on the crank, then that movement may not be too much of a problem. There is supposed to be some clearance there anyhow but it seems like it is a little less than 1/4". The suggestion about moving the clutch drive disk might be a good thought. If your engine knocks and it sounds like your clutch is where it comes from, that would be a sign the crank is moving left to right too much and the flywheel or clutch drive disk must need tightened. I guess I figure if you wait until you have oil pouring out of a main bearing, you might have cost yourself something that might have been prevented.

Someone makes a shim kit for flywheels as soon as I find out who it is I'll post again. I wouldn't worry too much about a loose flywheel just take a look at the splines to see if any are busted off. Some guys shove nails between the crank and the flywheel if they break a spline. If too many splines are broke you will need to get a flywheel, you should be able to get a used one for about $150. Also grab the belt pulley and try to move it around. If it moves a lot the tractor did a lot of belt work and you should figure on at least new main bearings or at worst a crank. Anyway you can't get too much money tied up in one of these motors unless you want to pull them or something. Good Luck

Try bracing the clutch assembly against the right tire with blocks of wood after loosening the flywheel bolts. Move the flywheel inwards to reduce play to less than 1/8 of an inch.

If it not spewing a lot of oil from the left main bearing while running, I would not worry about it.

I think the correct endplay for the crankshaft is .005" to .010". It's easy to check with a dial-indicator.
