    What determines if a crank is a good core or not?

    Hey guys,

    I'm tearing down a 1050 and finally got the crank block apart.

    It looks like most of the bearings are shot. Only a couple of them are smooth and quiet while the rest sound like skateboard bearings after its been ridden through dirt and puddles. Once of them has a lot of metal in it. In the bottom of the block there was some metal that looked like it used to be part of the bearing cages.

    No signs of water...and the needle bearings were ok...no failure there.

    So the question is if this crank is considered a good core or is it now a boat anchor?

    Thanks! Ron

    Bearings would be replaced during a rebuild. I believe they would be more concerned about something broken.

    Thanks...I've seen on ebay people selling cranks as cores....would this crank have any value to someone rebuilding a motor and their crank was broken?

    Thanks for that....I don't need this crank myself but I'm trying to see if it has resale value of some sort.

    Does anyone see anything wrong with the block? I haven't cleaned it up yet. I didn't see any obvious damage.
