Thanks. Much appreciated. Strange this is already leaking after the rebuild.That should do it.
Yes you can. But don't slide it out too far or the thrust washer on the inside can drop down ….Thanks for weighing in. I’ve read several of your posts on the subject. Can I just push shaft out carefully and put a new O ring on (with silicone)?
Thanks. Went to order the O ring and Toyota said it is NLA. The part number is 90301-18026. @orangefj45 Do you have one or does anyone know the size/specs so I can find one that will fit?Yes you can. But don't slide it out too far or the thrust washer on the inside can drop down ….
Is that the shaft out of your case?Just received the O ring. Thanks again @orangefj45. My transfer case is still in truck (pic in post #1 is image after my rebuild by restorer) and will attempt to replace the O ring without removal. I’m following the below steps and have a few clarifying questions in yellow.
Removal:
1. Remove 12mm retaining bolt and keeper, making note of distance of shaft protruding out of housing.
2. Home made SST - Using a 15/16 socket with 8mm stud, washer and nut screwed into shaft. Thanks @Coolerman (here is link)
3. Keep frost plug in T-case housing (front of shaft). Is this possible? I do not want to introduce another leak...
4. Slowly tighten nut on stud and back out the shaft just enough to access O ring. To avoid thrust washers falling, or shaft dropping inside of case, does anyone have the distance from rear shaft to O ring? It appears to be about 10mm based on the image I found below.

5. remove O ring ( if one was installed)
Install:
6. Install new O ring making sure to lubricate before placing on shaft.
7. Using soft hammer or drift, tap shaft back into place (Approx. 10mm)
8. Replace keeper and screw.
This is one of those procedures that comes with risk. Trying to mitigate it vs. overthinking.
No, that’s not mine. I grabbed it from the internet.Is that the shaft out of your case?
Looks like it's got some pretty serious wear ……… not worth installing that one again.
Thanks, man. Just measured it at 20MM diameter and 3MM thickness.Before you replace it is there a chance you have calipers and can post the diameter and thickness of the o-ring? I'm just thinking that could be handy in the future since they'll have to be sourced elsewhere. Good luck!
Yes, but it does come with risk of pulling shaft out too far and thrust washers dropping. Also, potential to create seal leak at the front end of idler plug. Here is my experience.So is backing the idler shaft out pretty straightforward?
