Pinion Seal - Type Preference

[RobertKB]

I am getting ready to install a new pinion seal on my differential. I have a good old style seal with the leather and felt which is like the original used (See pictures). I am just wondering if I should be thinking of getting a modern neoprene replacement which I believe is available. I know the original style should have the leather soaked in a light oil for an hour or so before installing. The yoke is in decent shape with only a small amount of wear on it. Just wondering what people's thoughts are on the two different types.

personally I would go with the modern neoprene..

As above...^^^^

Two opinions I respect. I'll start looking for one and report back with make and number when I find it............unless anyone out there already has that information. This is for a '51 Canadian Dodge D39, same car basically as a Plymouth.

Took my old pinion seals in and they matched the National number to a modern seal which I have pictured below. The seal is SKF 18880 and actuallly made in the USA. It has the double lip and is spring loaded. It crossed over very nicely as a pinion seal. My parts book which only goes up to 1954 shows it will work from 1937 to 1954, likely further as well. The jobber's parts book showed it going up to 1959. Hope this helps someone looking for the modern replacement pinion seal.

Interesting, that seal is in an SKF box with their number, but the seal has Chicago Rawhide number printed on it.   A case of "who's making what for who?"

A web search said SKF bought CR in 1990 and in the 2000's branded everything as SKF, but kept all the CR mfg. facility's

 

There was also a industry wide that worked together to standardize #'s on seals, bearings, races to make crossover easier.  When I did not search

I got a Sleeve at NAPA in Huntersville, North Carolina.

I am pretty sure Carquest has them as well. Its a pretty standard Sleeve.

Ask an Older Parts Guy that knows how to use an Old Parts Catalog.

The younger guys just rely on the computers and if they can't 

find something in 2 seconds flat - then it doesn't exist in their minds.

They will then tell you they don't have it or it isn't around anymore.

I know a couple (over 60) parts guys that can find anything with a caliper

and over 40 years experience they find what you need. They use computers too

but know how to scramble and find the part better than the newbies.

All of your lip seals are available by size & manufacturer at a local bearing supply. It has nothing to do with what year auto. We repair all type of gearboxes & electric motors which uses all sizes.

There  are lots of sizes & styles of lip seals. not just automotive .
