I disagree.
If you go to the trouble of replacing the front crankshaft/harmonic balancer seal, the seal ring/spacer ring should be replaced.
The part is currently ten dollars.
The seal ring/spacer ring should slip off the crank shaft, however I have encountered some that had to be split/destroyed to get them off.
If the sealing surface is less than perfect = you will be forced to go back in to do the job again = double the cost/time loss...
