Shifter shaft seal replacement
Hey every one, I have to fix a leaking shifter shaft seal. I want to replace all the seals that I can while i'm in there. Bike is a 2006 FLHTCi with 83,000 miles. How many seals are there to replace? With this many miles while i'm in there how do you feel about putting a new belt? TYIA...

I've removed the seal, by putting a sheet metal screw into and pulling. It is a semit skilled event. I read someone on here that pushed it out from inside, by taking cover off. I;ve have only taken that cover off once, and the gasket was a bugger to scrape. But interesting idea.
Also check with that mileage that the inner race on the shaft has not walked in towards the tranny.

At 86,000 miles it is a good idea to replace all the seals on inner primary cover and all the seals on left side of transmission.
I would also replace the sprocket spacer (it seals against the big oil seal) and the inner primary bearing inner and outer races.
At that mileage I would also replace the belt.
Double check these part numbers with the parts catalog: HD Service Information Portal
Big oil seal 12067B
Quad Seal 11165
Main Drive Gear Seal 12035B
Shift Shaft Seal 12045 (Cometic 9259)
Pulley Spacer 33344-94
Pulley 40250-94C
Pulley Nut 35211-91B
Lockplate 40251-92A
Screws (2) 3594
Inner Primary Bearing Inner Race (double check this part number, I think there is an error in the parts catalog, I think the correct part number is 34091-85A).
Inner Primary Cover:
Jackshaft Oil Seal 12066A
Inner Primary Bearing Outer Race 9135
Oil Seal 12052A
