inner primary seal 1988 FLHS
Hi all, I need to replace the seal on the mainshaft behind the inner primary, the one that goes on the mainshaft going into the primary. When I had my trans apart to have Baker rebuild the DD6, after a detent ball came out of the shift drum and ate up one of the bearings they sent one of their High torque bearing kits back with the trans, I guess as a " were sorry about that " consolation. Well, the seal on that bearing is now leaking and needs replacement. A stock replacement seal from Cometic is $2.75 from J+P, the required seal to go with the Baker setup is $6.50, + shipping from Baker. I was told by the sales woman they " are specially made for Baker." Maybe so, but it's not even a year old and no warranty. Has anyone else using the Baker High Torque bearing kit had any seal failures? I'm also wondering about the correct way to install the seal, with the spring side facing the trans or facing the primary. Thanks, Mike

seal
Thanks, that is the way I had it. I remember it now being called the "garter spring " but only because you mentioned it, appreciated. I'm curious to see what damaged the seal, all the parts aligned smoothly, and it took nearly a year to fail. Not curious to see how quickly I can R+R the primary. Again.

Use the All ***** seal 30-5216, it is a DOUBLE LIP, DOUBLE SPRING seal. It is a TTO seal # e-2142. I was not able to source the TTO seal from any place other than all ***** or one of there retailers. Clark has a double lip double spring also, but can't seem to find a part number to do a search for that one. It is a 25x52x8 seal.
To answer your question, yes, my Baker seal is leaking. Only a little, but it is a leak. Started leaking after about 500 miles. YD

I very much doubt if Baker has a dedicated Baker-only seal, although that can be checked once you get the darned thing out and can read the ID markings on it. I suspect any local bearing/seal supplier will be able to offer a replacement, however that may be a 'high spec' one, hence not as cheap as we are used to. Or go with YD's suggestions above.

I recommend going back to the HD bearing. A roller bearing is better choice for a radial load. If you are worrying about the HD bearing race moving/walking, it has been suggested on this forum to use some Loctite 620 Retaining Compound Green to prevent that. Another possible option is maybe you can go with an S&S race.
Just a thought on the Baker bearing. Without a bearing race for the IPB to ride on, if (when) the bearing fails you are going to have a much larger problem.

Thanks for the tip! I ordered the All ***** double seal, and hopefully that will be that. Actually ordered the All ***** kit, $19 on Amazon to get the double roller bearing as well.
