I've been having a recurring problem with oil leaking from my transmission into my transmission case on my 5/85 FJ60. It's happening again after only 15K miles. I purchased all the OEM seals and gaskets from Dan.
Then I was reading another thread (https://forum.ih8mud.com/60-series-wagons/208694-transmission-transfer-case-seal.html) where someone mentioned a "special double seal" that MAF had. I called MAF, and asked for the special FJ60 seal and gave the part number "NOK BW3386E" but the sales guy wasn't familiar with this number. He put me on hold and came back and took my credit card number for an FJ60 seal.
Then I was reading yet another thread where someone else was recommending using the FJ62 seal. So I bought one of those from my local dealer.
Here is what I got:
First Picture: this is the OEM seal for the FJ60 from Dan. Although it appears to have two contact points, it is what I call a single lip seal, because it only has a spring on one side. The markings on the seal are "NOK BE3383E". The well between the contact points came filled with grease.
Second Picture: this is the seal I got from MAF. It looks almost identical to the OEM FJ60 seal above except there is no grease in the well between the contact points. The markings on the seal are "90311-48012" which is the toyota part number for the seal.
Third Picture: this is the OEM seal for the FJ62 that I got from my dealer. This is a double lip seal. You can see that it has a spring on both sides and the seal is supported from the middle, between the two lips, not at one end. The well between the two lips is filled with grease. The marking on seal are "NOK BW3386E". The FJ62 seal is about 1mm thicker, but otherwise the seal appears to be the same dimensions as the two other seals.
So the "special seal" that was referenced in the thread link above is really a seal for the FJ62. I also find it interesting that the two seals I got from Toyota are marked with NOK numbers and the seal I got from MAF is marked with the Toyota number.
I'll probably install the FJ62 seal when I reseal my transfer case, unless some tells me I should not.
