newbie here.. 16 touring.
I'm installing new (used rear) rear bearings.
I am using the new neoprene inner oil seal, new sleeves, and the new outer neoprene outer seals.
My question is about the inner oil seal (looks like a baby nipple with the end cut off). Should that go in with the nipple part sticking outward or inward?
Right now, I have it sticking outward and when I put the bearings in, I'm getting push-back so I can't install the outer seal. I'm thinking I may have the inner seal in backwards. :-(
Am I the only one who makes these mistakes?
It should be installed with the 'nipple' on the inside. I coat it with WD40 first to make it slide a little easier.
Check out Steve Jelf's video on the process:
Darn.....how do you suppose I'm to get that out with out damaging the seal?
I'd skip the WD-40. You don't want to contaminate the sealant your going to use on the edge of the seal. Just go with a little grease on the axle as the video shows.
To remove the backward seal maybe you can use a piece of coat hanger or welding rod with a U-shaped hook on the end. If you can slip it in between the neoprene and the axle, perhaps you can turn it to catch the inside of the seal enough to pull it out.
In case I'm not the only bonehead in the group:
A backwards inner seal can be removed by slipping a small flat head screw driver between the axle and the seal, and then slipping a coat hanger with a bend on the end alongside the screw driver.
If you connected a air hose to the rear axle fill plug you could low it out without risk of damaging the new seal
