Trying to replace the seal, never done it before, the primary was last touched by Vallejo Buell couple years ago. I don't know if they put in the seal I'm replacing or not.
When I took off the primary case, the seal around the shift shaft it rubber, enclosed in a little metal ring. Not being clear on the concept, I scooped out the rubber from this little metal ring. My new primary seal has to metal ring. I'm working on the deduction I needed to take out the metal ring as part of the seal. (Not talking about the shaft support bushing.) The metal ring prevents the new seal from going in, it doesn't show in any pictures on this site of how to replace the seal.
Is there any version of this seal that has a small metal 'tire' around the circumference? Just stuck in the middle of this, can't find an example of what I found. Thanks for any insight.

From what I recall of that seal, it is like every other seal I have ever replaced, and its a metal outer ring with a rubber inner ring. The part mating with something stationary is metal, the part mating with something moving is rubber (or nitrle or whatever).

The best way I have found to drive them out is sockets (which come in lots of nice sizes) and a vise. Put a little socket on the "push" side, and a big socket on the "catcher" side, add some heat with an electric heat gun and crank down on the vise.

You could tap the small socket with a non marring hammer as well, or a hammer and a block of wood, but it has a higher chance of hurting something.

On the inside of that seal is a brass/bronze bushing that the shift shaft goes through, so I'm not sure how you'd get to the seal lip with a socket to push it out. And of course, all that assumes that the cover is off to begin with. But it's easy enough to push it out with a screwdriver from the inside if the cover is off.

If removing it with the cover in place, hook picks will work just fine, but they destroy the seal of course. If the metal spring ring got left behing,Yank it out of there with a pick, then push the new seal in. BUT, either put a small corner of a baggie over the splines, or wrap them in electrical tape, prior to sliding the new seal over the shaft, or you might be replacing it again. The corners of the splines are kinda sharp and can nick the seal.

When I take a primary cover off, I'll generally replace that seal. I yank it out with the cover off (much easier with the cover off), and then DON'T put the seal in until after the cover is mounted. It's a big enough PITA to get the cover on with the gasket falling off, and the primary chain up over the shoe, etc, without worrying about nicking the seal as the shaft goes through the hole. It's easy enough to put it in once the cover is mounted.

The outer seal is all I'm talking about, not the long bronze bushing.
Upon further review, it looks about like the picture on the JP Cycles web site.
The one I just bought looks like the bottom one (I can't tell if this is the one American Sport Bike sells, it looks sorta like it.)
The one I just took outa the bike looks just like (or is) the top one.
The one in the middle has the number that matches the 2000-2001 M2 Parts book I have.
So I'm not clear, is any of these three the one I want? Which one?
Thanks everybody!

What Al said. The baggie corner works VERY well.
If memory serves (probably not, I'm into my 3rd beer, it's been a long week....) I use a 12MM deep socket to seat the new seal. Sockets differ by manufacturer so use one that fits...

If you take a 1/4" screwdriver and bend the tip 15 to 30 degrees about a half inch from the end and round off the sharp corners of the tip, it becomes a very useful prybar. Catch the metal rim of the outer seal with its point (cover off) and the seal will lever right out. My own bronze bushing slips out easily, making it easy to reach the seal from the inside but this may be damage as a result of the local H-D shop neglecting to re-torque the primary nut after replacing the chain tensioner. By the time I got home from the shop the shifter shaft was rattling loose and the seal was popped out and half my primary lube was on the ground and frame.

I can get it out and in, my question is which one should my M2 use?

Is any of the 3 OK, or should it be the Parts Book number one (the middle one in the picture): 37101-84.

Because I asked the HD parts counter guy for this part number, and he gave me the bottom one in the picture, I wondered if the part number was updated, or he gave me the wrong one.
Or perhaps now any of the three seals would work?
Thanks.

I seem to have run into a similar issue. I'm assuming I just pry the metal ring straight out and then replace it with the newer style seal?

And I'm also guessing the seal should be flipped over before it goes in?

For anyone who looks at this down the road, I have confirmation that this is indeed the right thing to do (pull the metal 'tire' out and put the new seal in with the 'open' side facing into the primary).

Thanks for posting the followup. I was trying to figure out the best answer, seems like either would work well.

Steel out makes it more durable, and easier to pull later. But seemed wrong to me somehow, so I kept my mouth shut. : )
