Main Shaft Seal
Anita B via Facebook
A: The bushing that supports the main shaft is probably worn; allowing the main shaft to have excessive runout. New seals will not stop your trans from leaking. The trans will need to be torn down and rebuilt.

The bushing may have moved inward on the shaft.
Love your comments
I have a 2004 H-D Softail FXSTI my speedometer went out I thought so I got one from the dealer installed it and my speedometer is still going all the way up after started. So do I have a bad sensor or am I over looking a fuse some where? Thank You, Robert Coy
Hi, Robert. Inspect your harness. Verify that you have +12vdc and ground. Inspect your speed sensor harness. Also check for stored diagnostic trouble codes. https://www.fixmyhog.com/videos/electrical/

It is common on a 4 spd transmission for the mainshaft to be worn .002-.004″ where the main drive gear bushing rides on it so when over hauling a 4 spd trans we usually end up replacing the mainshaft as well as the bushing or you will be back in there shortly
