So I finished reassembling my motor (b18b) and go to put the harmonic balancer on and notice it's a little loose on the crankshaft and the key way on the crankshaft has a corner of it cracked off. So as of right now I put the balancer on the crankshaft and torqued it to spec (140 ft lbs). It seems fine spinning the motor over it's not loose or have any play but I would like a second opinion before dropping it in the engine bay.

I bought the motor fully disassembled, that's why I didn't notice it sooner.

Thanks guys!
