• To ALL forum users - As of late I have been getting quite a few private messages with questions about build ups here on the forum, or tech questions about your personal project. While I appreciate the interest, sending me a private message about these topics distracts from, and undermines the purpose of having a forum here. During the day I wear many hats as a small business owner-operator and I work tirelessly to provide the absolute best service possible to you, our valued customer. When I created this forum I rounded up some of the best minds I knew so that any tech question you might have could be asked and answered by either myself or one of my highly experienced moderators, this way the next time this same question is asked the answer can be easily found and utilized by the next IH enthusiast having the same question. This allows me the freedom to run the day to day operations of the business and minimize the impact to shipments and shop activities that these distractions can cause. It is of the up most importance for me to complete the daily tasks in order to best take care of you our customer, all the while providing you a forum to get the level advice and input you have come to expect and deserve from the premier IH shop in the country.

    So with that I ask that anyone with a question about one of our build ups or a general tech question to please use the forum as it was intended. I am absolutely available by telephone to answer your questions as well but at times may direct you back to our website to better field your question or questions. Most other private messages I will be glad to answer for you.

    Thank you for your understanding.

Dana 27 Rear Pinion Assembly


New member
In the process of tearing apart, painting and rebuilding the rear axle in my ‘66 800, 152. Dana 27’s 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!


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.
