Shifter arm seal replacement
Has anyone ever had to replace the shifter arm assembly seal? I had a slight oil leak behind the inner primary, so I finally got the ***** to tear it apart and found it had a small leak coming from the shifter arm seal and also the inner primary seal was leaking also. The inner primary seal looks to be a pretty easy fix, but the shifter arm seal I'm not sure how I would go about getting it out. I have it apart as far as taking off the small retaing ring and washer where the shaft comes out of the tranny. The seal is #5 in the manual picture. See pics below.This is an 07 wide glide.

Well the cheep hard way is to use two picks and work it out. I know for my alison tranny I have a tool that slides over the shaft and has a spiral on the outside and it thread it in and it has a bolt in the end of it and once it threads itself between the seal and shaft you used the jackbolt to pull it out. I know its a bad explanation but I'm sure there is aspecial tool for this seal or just work it out with some pics.

When I did mine on a 01 FDXL I used small/long sheet metal screws. I drilled two small holes on opposite sides of the seal to be removed (use the new seal as an example of where and how deep the holes need to be). Insert the screws just enough to get solid contact with seal (use screws long enough to clear shifter pawl once in place). Then I used two smaller vise grips on the end of each screw an pulled old seal out. When inserting new seal I use a deep socket that matched the seal but cleared the seal boss in case and the shifter pawl. Be sure to lube the matching surfaces to the new seal and the seal boss in case. Gently tap seal in place. It will be very important not to damage the the shifter pawl or the case boss which prying out is subject to do. Hope it helps and Good Luck.

Did some searching using this search ID https://www.hdforums.com/forum/searc...archid=7832724
in the Tech Forum's Section/ Primary/Transmission/Driveline/Clutch
and (amongst others) I found this thread:
Shift Shaft Seal.
IMO forum member ajayrk has the answers for you:
I have replaced those seals on two bikes in the last two weeks. Removing the seals is easy. Getting to them is a little harder.
You have to remove the outer primary, the primary drive train and the inner primary. Compensator has right hand threads and the clutch basket nut has left hand threads.
You have to remove the two screws that fasten the starter to the transmission and primary. These are very hard to reach.
You then remove the sprocket which has left hand threads.
To remove the shaft seal, you remove the lever, a snap ring and a washer form the shaft. Drill two small holes in the seal body and screw in a sheet metal screw to force out the seal.
Main gear seal is a little easier. Pull out the sprocket spacer and catch the edge of the seal with a seal puller or screwdriver and pop it out. You may want to replace the sprocket spacer if it is grooved where the old seal ran on it.
If you work fast you won't loose much trans oil when you change the main seal. You can start it in place by pressing it in with your fingers.
It will be very dirty under there so plan on using a few cans of spray cleaner to clean it up.
Clean the back side of the primary. Be sure to tape over the bearing to keep out trash. Use a seal puller or screw driver to pop out the main shaft seal. Drive out the starter shaft seal with a socket or screw drive.
Harley has redesigned the main shaft and starter shaft seals to improve sealing. The main shaft seal now goes in backwards. It is marked oil side.

According to this thread Shifter Shaft seal other numbers some members have used:
Cometic SEAL SHIFTER SHAFT C9259
SKF/CR oil seal #4260
National oil seal #472810
Both are double lip just like Cometic.

'05 Dyna with about 30,000 miles ... needed my shifter shaft seal replaced .... used a similar technique, but used a punch instead of a drill and was able to pull it out without using the screws .... Replaced with stock H-D seal ....
Only been about a thousand miles since replacement, so could not tell you if it is as good as SFK/CR or National seal ....
