Steering gear oil seal

[SuperB]

Does anyone have a part number (Mack or aftermarket) for the cross shaft oil seal on a 1965 B61? The gear box number is 20QC319AP1, and this seal is for the shaft where the pitman arm attaches. The seal has an OD of 2.250" and the shaft diameter is 1.750". Any help would be greatly appreciated.  Thanks 

My parts book only has the parts breakdown for a different box, with a seal number of 364SZ66. This seal OD is too big (2.500"). 

 

I was able to find a CR seal that should work. 👍

Can you figure out what brand steering gear you have ? I have several manuals for the Sheppards and the old TRW /Ross  HFB64  and 70 gear boxes. The seal you are locking for they refer it as the sector shaft seals

OK thanks right now I’m looking for a rebuild kit with the sector Shaft, bearing I was originally going to look for a rebuilt box, but I really don’t think I need any more than a kit and the bushing Thanks for all your information…. Bob

I had bolted the box back into the truck before I saw your message Mackpro. The only info I got off of it beforehand was "GEMMER" and "7DC06". I used a CR 17231 seal, which seemed to be a good replacement for it. It was only a single lip seal unfortunately, but I think it will last as long as I do
