Seeking National Seal part number for transfer case input seal for 78 FJ40 (1 Viewer)

[Cirbo]

Not sure if anyone can come up with the Timken or National replacement seal part number for the one piece transfer case for a 78 FJ-40. I am seeking to find a local replacement for the input seal between the transmission and transfer. Part numbers I have come up with so far are as follows:

NOK AE24931
OEM 90311-42014

Searches have not yielded any others numbers. Was hoping for a local source.

Thanks,

Is there a reason you don’t want OEM? It would be next-day at any Toyota dealer in the US for about $12.

OEM seals are like eggs. Price went up 256%

I use seal interchange lists. Here's a sample:

Toyota doesn't make seals, or bearings, for that matter. There's no reason not to buy either from manufacturer's distributors; the OEM factories do it all day long.

The NGK number you listed doesn't appear to be a seal.

This probably will not be the exact seal, you'll have to physically compare them to be sure it'll work for you, but it's the case seal is generic oil seal, not a wheel seal, so I'd think it'd work:

Generally, the difference between generic seals, and bearings too, is the quality control the manufacturer provides. The thing that makes them generic is that they are all made to the same original design specifications.

Excellent data Fred. I actually spent some time with that PDF, but came away unsure of the results. Quick measurements showed the following:

Its so nice to see people ask for help and then actually follow the advice. Yep sucks to have to pay nearly 3x for something, but it is the correct part that will fit and work correctly for a long time. Putting in a cheaper part might work but taking everything out to replace it when it fails will suck up more labor/time/money than was saved by using the cheap part.

When the shop rebuild the transmission on the Hillers and Bells, they got all new seals/bearings. The local operator bought a much cheaper rebuilt unit. It didn't last until the next scheduled rebuild because they reused parts that were still in spec. After about 3 units the operator figured out paying more up front was cheaper than early failure. Nothing like having your machine on the ground during the busy season. If you are not flying you are not making money.

Is that a ranger torque splitter. ? Haven’t seen one of those in a long time. Cool.
