SUPER A AXLE SEALS???

Wondering where to get the inner axle seal where the optional seed plate drive comes out at. It looks like a two piece seal, but when I pressed it out it is only one seal, with two pieces inside. One is the cup seal, and infront of that is a felt ring. It has a number of 53599-D on it, and napa and carquest cant CR it to anything that looks like it. Can I get this from other than the CaseIH dealer? Also, is there supposed to be tranny fluid down there, or just grease? Thanks.

Lots of older seals like that are now replaced by using 2 modern, narrower seals.

There's some alternate numbers on the CNH site:

#37 Part # 53599D Oil Seal, Seed Plate Drive
(Optional With 264698R91 Or 357768R91)

I'll look in the C/R cross reference tomorrow.

There is supposed to be 90 gear oil in the final drives.

NONE of those 3 numbers shows up in the generic cross references I have. If it's not available from CNH, it'll have to be matched up by dimensions.

I've been prowling the books and may have a handle on at least what the issue is in trying to cross it. This assumes that the felt seal is essentially the same diameter as the shell seal and rides to the outboard side of it.

The R91 suffix on the alternate part numbers suggests that there are two pieces to this seal, as only one part number is listed (and only one part shown in the drawings) between the washer and the retainer. This would make sense if you're finding both a conventional seal-in-a-shell and a felt ring. That's pretty common on IHs. You'll find a similar felt ring on your front wheel spindles, for example, but there it's listed as a separate part. If the R91 is actually a "kit" of two parts of different types, that would/might explain why your counter guy can't find a direct cross.

So I'm thinking the options are to 1) try your CaseIHNHFord dealer using, having them search on your D number and the two R91 numbers that Bob came up with -- expect them to be quite proud of it, it'll likely come dear -- or, 2) if your old seal is measurable or you can measure the seat and the shaft diameters, your counter guy should be able to look them up that way. If you do wind up going the latter route, and can't come up with the felt seal, it's altogether possible that doubling up on the shelled seal as Bob described, would give you the same or a better actual seal.

HTH

HTH you were on a good track with the R91 theory. Unfortunately, IH considered lip seals to be assemblies. Under the R number system, they are pretty well all R9x.

Here is the process I went through:

I found the same 3 numbers in the Super A manual as the rest of you. Thought the 140 may have essentially the same seal with a newer part number, since the manual was newer. Found the number 273563R91.

Then went to Messick's and typed in 53599D. They said superceeded by 38220R91. Clicked on that number, and they listed all the above numbers as superceeded by it (at $12.xx).

On a hunch, I checked that number in the ATIS Cub FAQ. Found the same number listed for the same application on the Cub. Listed cross references:
Federal Mogul 472070
National 14702, 472070
CR 18104 (use 2)
National 470267SSR
CR 512309BT
These crosses are what various CUb owners have found that worked for them. I have found CR 512309BT in an IH reference. Check the dimensions, but that is probably what you need.

NAPA crosses 18104 to
Seal I.D. : 1.8130"
Seal O.D. : 2.6270"
Width : .3130"

and it isn't any cheaper than Messick's.
