Is there a way to tell if (removed) harmonic balancer is bad?

I have a known good pulley but without mounting holes for CPS disc… No way to find new one here - so I wonder if I can use one removed from car. Reason for removal was squeaky cold starts and lot of oil/grease in crank pulley area. Belts are heavily glazed so I hope that it was oil leak problem. A/C compressor is throwing some gunk around - there is a blac trail on bonnet…

Visual inspection would give an idea without really being conclusive. You are looking to see how intact the rubber bonding between the 2 Halves is , if its looking taddy , balling up , torn then fair chance its no good,

I guess you could lock the centre in a vice and grip the outer with vice grips or the like and see if the outer can move .. Crude I know but only thing that comes to mind.

The test in situ is to mark a line between the 2 halves ( chalk or the like ) if the removal was based on squeaks the balancer may not have been to blame , when they do separate the noise is more constant and probaly louder than what you had .

The crack is not supposed to be there, or am I wrong?

If that scratch at the upper right of the picture, from the inner to outer portion is an old scratch, it hasn't slipped yet.

I'm referring to that crack (it looks to me like a crack) in the lower middle of the last pic, between the numbers on the balancer.

Thanks to all for ideas, I will report back latter.

ps. line that looks like crack is from casting but I will double check.

Today was a good day!
Crankshaft pulley seems to be fine - no more screeching at start up. Oil pump o-ring was all dry and cracked and crankshaft seal was bad.
All dry and quiet there now.
Thanks again for help!
