I’m not finished with it yet, but here’s a peek at what I plan to do to fix my transfer problem. I’m waiting on a slave cylinder (hydraulic actuator) to make sure I can make it fit and vent it, then I will get a nut machined down so about half of it is a sealing surface. The seal is a SKF 10766, available at Motion Industries for about $13. If this works I don’t know that I will offer it to anyone else because the machine work is going to cost me about $125-150. I would think that this will be a real fix.

 

good luck, rooting for you! that's some crazy cool innovative thinking and manufacturing ideas you got going!

 

I like the approach, hope it works for you. You won't need to offer it to the public, if it works HD will just steal the design. Good luck

 

They wouldn’t have to steal it, I would gladly give it to them. Even with all their ineptness I think they would have the assets to do it better than I will be able to do it. I just wonder if I can get the dealer to install it for me, would hate to put it in myself and then end up with a sumping problem and have my warranty rescinded.

 

It would have to be approved by HD to keep the warranty.

 

Any concern with deterioration/wear or movement of the rubber seal?

 

Not that I can ascertain. The seal is made for this type of service. As long as the cover is machined well and the nut is machined well it ought to hold up as well as any seal in the transmission.

I wish Stoned the best of luck! I have been following his thought path. But there is one thing I don't get and this is why. A ball bearing will unload be it oil or greased lubed through the path of least resistance. And that path is it's self to the lower side of pressure. We know the leak path is through the shaft with the actuator rod. The lip seal will fail. If it's made out of Buna it will be quick. It should be at least Viton. Teflon would be better but it will groove the shaft much faster. Thus failure. Lip seals at best are for contaminate protection. I'm not getting it....

 

It may well fail. It is made of nitrile which has a very good resistance to oil. It will be running on a grade 8 nut milled down to a sealing surface so it shouldn’t groove too quickly, but if it does another can be machined. The other side of the transmission has a seal on the output shaft that seems to hold up pretty well. I’m not aware of many failures of those seals. What it boils down to is at least I’m looking for a solution. Granted it is the MOCO’s responsibility to find one, but I’m not going to sit around for a couple years with a bike I can’t ride the way I would like to, so this is where I’m at.

 

I don't want to see failure on your part. I just don't see how the bearing is pumping anything into the primary. That's not what bearings do.

My solution is Baker. I have no warranty. And it's clear to me HD hasn't a clue.
