I have had several duh moments lately...

I was putting my new timing set on tonight and did not have a longer crank bolt handy, so I used a deadblow (plastic mallet) to install my lower timing sprocket on the crank.

Took quite a few good licks. Motor seems harder to turn over now by hand... (It's just the assembled shortblock, crank rods and pistons. Timing chain is not on.)

Last week I could mostly spin it by using two hands on the crank, now I can do that about half the rotation, but it seems to hang ever so slightly. Spins ok with a wrench.

Am I just being paranoid?

What should I check for damage? Main or Thrust bearings?

Thrust bearing probably doesn't like that... easiest way to get the lower timing sprocket on is use the old timing sprocket with a puller bolt to give you extra length and gently pull it on.

If your thrust bearing had more clearance than your rod side clearances, then then possibly a rod hit the crank before the crank hit the thrust bearing.
