Spun Bearing

The term usually refers to "friction bearings", as opposed to needle or ball bearings. Friction bearings are found at the crankshaft and rods and camshaft. Ordinarily, a spun bearing is related to a crankshaft bearing. Use a lot of caution when obtaining this engine. The reason is no one can be sure why that bearing spun to begin with. It's supposed to be stationary of course. Anyway, either the engine was abused some how and it spun around, or it may do it again with a new bearing.

You're looking at doing what we call a bottom end job. If you have one bad bearing you must replace all the others as well. Also you will need to check the crank shaft to be sure that the journals haven't been galled as well. Galling is when some of the bearing material is left on the surface of the crank shaft. If some of the bearing material has gotten into the oil passages for the crank you will have to replace it as well. If it spun a bearing then the oil pump wasn't working or there was no oil in the engine to begin with. Bad news all the way around. I'd stay away from it. Do you have the money to go thru all of that?

I would look for another motor, This can be a very expensive repair as the crankshaft may need to be replaced and the block line bored to correct excessive runout due to the spun bearing. And any other damage that can be seen until the engine is taken apart.

A spun bearing is due to a lack of lubrication to the crankshaft. Either a rod or main bearing fuses to the crank, causing it to spin inside the cap/rod. There is usually considerable damage to the crank, block or con-rod. Can be very expensive to repair.
I would only use that engine for a boat anchor.

It is a mechanical failure of that bearing. My understanding is that the engine will need a rebuild.

It usually means it's a rod bearing.And if it is there's usually more work then just a bearing.It can cause the piston to hit the head which means the the piston and the the head can have damage. hope this helps
