5th gear seal leak
Just converted my93' Softailto a chain to accomodatea 180 tire. Following ashort ride, I noticed a leak coming from the drive sprocket area. I tore it down and found the leak coming through the 5th gear and main shaft. The outside area of the sprocket was wet with gear oil.How do I replace this seal? Any help on this matter would be greatly appreciated.

RE: 5th gear seal leak
this is how i have done it many times. you have to get a small hole into the steel part of the seal andscrew a wood or sheet metal screw into the hole. don't drill into the trans case aluminum if you do your screwed. don't screw it in all the way. a couple of threads is enough.take a claw hammer and pull it out like you would a nail. seal should come right out. i drill a hole with a 1/8 drill bit. i put some masking tape about 1/4 inch from the end of the drill so it doesn't go in too far. some people think thats not the way to go but i never had a problem. if your not comfortable doing it like that you might be able to get a hole with a nail or a small punch.

It looks like its coming from the primary side. When I installed the new chain sprocket, I replaced the seal you mentioned earlier and all the seals on the inner primary cover. I know it does'nt make any sense but it seems like its leaking from between the fifth gear and main output shaft.It is definitely gear oil and not primary oilthats all over the drive sprocket. ?????

RE: 5th gear seal leak
I had somewhat the same issues you are going thru on my 01 Heritage. My leak looked like it was between the inner primary and trans. When it got tore into, my bearing/race on trans shaft which goes into the primary was walking into the trans. It was replaced with a one peice sealed roller bearing. Might be the same issue that you got. Mech said that shaft houses 5th and 1st gears. I spotted mine before it walked on into the tranny and caused alot of damage. Hope you get it figure out.
