oil leak

I developed a nickle size oil spot while parked overnight. Leak appears to be from seat around 32 tooth pulley area. what could be the cause and fix. (expensive) ?

Are you a do it yourself type, do you have a H/D shop manual ? There are multiple places for a leak in the area, make sure you get it right the first time. Good luck

You are right about multiple possibilities for leaks in that area. I wont be doing the work myself. That's a job for experience. I did get some good info from internet videos.

I also got one like you. I do know that it's trans oil since I use a different oil for the tranny. It was suggested to me by BaggerPaul who is a very experienced tech that it may be from the shifter shaft seal. Apparently it's common. For me, it's a a sign that I've joined the Harley Owners Club! I myself won't be ripping into the repair for Such a minor leak. Maybe when I need a belt.

Its definitely a tranny leak. Even though my leak is minor and just started, I am running a big motor and go through the gears at times and feel it necessary better now than later for repair.

I also believe its the shifter shaft seal, but will also replace others.

Better to fix now if you can do than put off, Have a 34 tooth drive that I want to put on, where do I start and stop lol.

Seems like a lot of work and other seals while apart, maybe a drive belt too, for a nickel spot . But then again , wrenching is fun! My preference would be December project not now when the season is starting.

A good flash light and a small mirror and wait till its dark out and you'll find it.After I got my baskekcase on the road I had a bad leak and thats how I found it.It was leaking down the side of the tranny between the pully and tranny and yes it was a BIG job ot fix.Good luck

I put the bike on a stand for a better look. I saw oil tits at 180 degrees on the 32 tooth primary pulley. Did not see any other leaks ? I think you are right about the inner bearing race and seal leaking. Video repair tips confirm what you said hotroadking.. I wont be attempting the repair myself.

Gonna do, Thanks

Hotroadking, do you have a part # for this 1 piece bearing and the distributor that sells them. The last one put in my bike was 12-0309 left crankcase main bearing set which consisted of the 6 piece set. Not a 1 piece assembled unit. I am having trouble locating a 1 piece bearing.

The 12-0309 left crankcase main bearing set was installed may of 2015. I have approx 2100 miles since the install and now a leak.

Hotroadking, I must be missing something. I talked to a tech at baker transmission about a "1 piece bearing set". I have a 2011 street glide. The tech said they do not have such a set for cruisers. Furthermore he said they cut out with the Hi torque bearing sets after 2007 ? ( something about a change in shaft size ) ?
Timkem has the left crankcase main bearing set - 12-0309 which consist of 2 tapered bearings, 2 races and both OD split lock rings.
Are we talking about the same thing ?
