A reader sent me the following question. He’s in the process of doing work on both :
“What is the best way to stop leaks in a transfer case and t-90 transmision? Do you have a any tips?”
My answer was the following:
I have found the most success using liquid gasket and following the directions (as I remember them) …
1. Clean the parts carefully
2. Put on the liquid gasket and put it on with bolts finger tight
3. Wait 24 hours
4. Tighten to spec.
Anyone have additional thoughts, tricks or alternative ideas?
I use it as a maintenance guide…If it’s not leaking oil, then it’s probably out and needs more……
In all seriousness, I’ve had terrible luck with trying to seal up jeep T-cases… No easy answer..
Thanks David, I have found some interesting tips, specially in this trouble parts:
– T18 to T90 oil passages
– Shifter rails caps (mine doesn’t have any)
– Correct felt seal on output shaft
– Use a little amount of rtv in the bolt’s base
Tomorrow I going to assembly both taking good cares…I will tell you if there is success.
Try putting a light film of heavy duty bearing grease on the area of the output shaft that is touched by the output seals. That will help reduce the chances of the seal adhering to the shaft.
Good luck,
– Dave
Solved!, the main trouble were the shift rail caps.
