Q: I changed my front mail seal and Harmonic balancer.

asked by on

I changed my front main seal and harmonic balancer however the crankshaft moved while doing so, how can I bring the crankshaft back to it's original position so I don't mess my motor up?

My car has 180000 miles.
My car has an automatic transmission.

The front crank shaft damper is on a key way and it should not matter if the engine moved when loosening or tightening the damper harmonic balancer. The camshaft will move in and out a little bit and this is normal.
