00 np242 rear output seal

[garr]

I replaced my damaged np242 with a junkyard case, I opened it up/inspected/resealed case/hack& tapped it/replaced seals.
When installing the rear output seal I noticed it went in too easy, I mean I could press it in by hand, so I spread some ultra black RTV in the opening before setting the seal in place. Is it normal for this seal to go in so easy?

I don't think any seal is supposed to be hand tight. They do make a locktite that is specifically for races and seals. If this ends up leaking or backing out, get a new seal and use that stuff instead.

No, seals need to be driven in. Maybe the seal you got wasn't the right one or put in the wrong box.

Funny I just checked a 242 I have with an 10/95 build date & the seal pocket (or whatever the spot where the seal mounts) measures a few thousands of an inch smaller than the late 99 mfg date 242 I'm working on, odd!
If the NAPA & ADPTY brand seals I ordered don't fit I may have to swap out rear housings.
Also odd thing I found is that the late model 242 has no lock ring & washer directly behind the oil slinger like earlier transfer cases have, no slot cut in the shaft for the lock ring at all, just a smooth shaft. So caution has to be taken when mounting the slinger not to contact the seal.

I just rebuilt a stock 242.. the seal had to be driven in.

Was it also missing the lock ring & washer directly behind the oil slinger?
I wonder if the lack of the lock ring groove in the shaft makes the shaft stronger?

It wasn't missing, some of them didn't come with it. This 2000 XJ transfer case was put into my ZJ. The one on my XJ has an SYE, but it didn't have the lock ring either.
