Default Dana 27 Rear Pinion Assembly

Hello-
In the process of tearing apart, painting and rebuilding the rear axle in my 66 800, 152. Dana 27s front and rear.

I have both the service and part manuals. Each references an oil slinger and gasket between the front end bearing and pinion seal.

The pictures show my assembly exactly as it came out of the axle. I seem to be missing one of those 2 components.

Anyone have an idea which one?


Any help/ info would be greatly appreciated!

The singer is the big washer behind the bearing and before the yoke. The seal is fixed in the housing before the yoke goes in.

Thanks for the reply Winchested!

Looks like I have the slinger then? The manuals have 2 components between the bearing and the yoke.... I know IH has been known to wander from the manuals. Should I be looking for another gasket to go with the slinger before the seal or reassemble it as it came apart?

Thanks again!

No other seal is needed.

The part number for the "gasket" is 127969R1, if you Google that number you will see Scout Parts has a picture of it. It is just a thin paper gasket that goes under the seal. The modern day seals have a bead of silicone like stuff right on the seal that I believe is intended to take the place of the paper gasket.
