Rear Pinion Seal Adapter

[mix4coal]

I am in the process of replacing the rear pinion seal. My work has offered to make an adapter so I can use a rubber seal and not the leather one. Does anyone know the diameter of the rear seal housing so i can have them make the adapter for it. My calipers are not deep enough to measure it because the shaft is in the way. If anyone can help, that would be great. Trying to get this done before Labor Day! Thanks

Just measured it with a caliper. It's 4" exactly. The seal measures at 4.025". Not sure how that's possible, but there it is!

Thanks Jrod. My work measured the seal I removed at 4.015". They wanted to know the size of the housing so they can machine the carrier to fit. The stamped seal will give when installed but the solid machined carrier wont. The little calipers I was using aren't big enough to reach around the shaft so I got reading from 3.85" to 4.2". Cant trust those measurements. The inner seal isn't a issue. They will machine the inner to fit the seal I gave them. Do you think I should have them machine the carrier to 4" or a hair over?

The original seal is a hair over, I'd think going with that measurement would be the best way to go. Not entirely sure though...

FYI. Not sure why it's upside down but you get the idea.
