Technical Front Disc Brake Oil Seal?

I'm embarr***ed to have to ask this question because I've done this job before, had the same problem, and can't remember what I did. I'm putting disc brakes on the front of my 1941 Ford truck. I'm using Pete and Jakes kit. The oil seal in the back of the hub is not your typical oil seal. Most are flat on one side, the neoprene is on the other side, and you just tap them in with a piece of wood, or if you're sophisticated you have an installation tool. The part of this seal has a small flat but also has about a 1/4" piece of neoprene sticking out. The other side is the usual U shape also with a piece of neoprene. I can't decide which side goes toward the bearing. Can someone help me with this?

 

My first thought is the small flat should face out, but to be sure, does the seal have a lip on it? The lip should angle in towards the grease to keep it in the hub.

This might help

 

Does it look like this type of seal before I respond.

 

There's the problem, it does not look like the typical oil seal that's posted, that would be too easy. To make matters worse, it's somewhat angled on both sides. Where the flat is shown in the posts there is the 1/4" of neoprene, and the flat is only about 1/16" wide.

 

I remember that type but have not seen one for some time. Like you I don't remember. I tried to find that type but failed, sorry. Can you post a picture of both side's of your seal for us ?

 

Probably should have posted pictures to start with. I hope they're good enough.

 

Can you lube it slightly and slide it on the spindle by itself and see what it rides on/against?

 

Oh wow not the type I thought of. That is interesting.

 

I hate to say this, but I've tried it both ways, and it looks like it works both ways. This the reason I'm having a problem.

 

That seal style seems to be a bit more common on disk brake apps. I don't remember what that style is called though.

 

It should go in like the second picture. The primary seal always goes towards the bearings

 

pete and Jakes does have some of their installation instructions on line,not sure which kit you have. Tech should also be able to help you out 1800 334-7240

 

So there's no mistake, you're saying the large neoprene portion goes towards the bearing? That's actually what I thought, and I already installed one that way when I started having second thoughts.

 

Thats what i would think. Looks like the lip of the seal is on the large neoprene portion. You want that closest to the bearing

 

The lip always goes towards the grease. In other words, towards the bearing.

I know Pete and Jakes would have the answer, but I was trying to get something done today. Thanks for all the help.
