Hi there, question about the crank on a 97 ultra 680. I bought a case and crank online and it was listed as a 97. I split the cases to inspect the crank and replace the outer seals and I noticed two tan seals on either side of the waterpump drive gear. Is this a 96 crank?????? If I understand right from reading a couple older posts, the 97 drive gear should be open to the crankcase not sealed.
