Outer Limits 4x4 Board

I have just had my LT85 Gearbox rebuilt and new seals fitted to the LT230 transfer box as it was leaking big time.

Unforunately I still have a leak that shows up after as little as 20 km's.

Most of the oil is coming from the Transfer case, but a little is from the gearbox. The leak shows up on the mating faces between the gearbox and transfer case (input side of the transfer case).

As all the seals are new is this a sign that the job has been botched or could it be caused by a blocked breather ?

Any other ideas ?

Thanks

It's easy to screw up the input seal when you're bolting the T-case back to the gearbox.

Can you identify which oil it is that's leaking out?

Thanks for the reply.

The transfer case has a pink oil (redline) and the gearbox is filled with a Blue oil.

Most of the leaking oil is pink (transfer case) but there is a small amount of the blue (gearbox) oil.

What KB said - best way is to slide the seal over the mainshaft, line the t-case up, then fit the seal just before the t-case is mated to the box.

Well, you should be careful because if you are NOT in-line between the transfer case & the transmission the output shaft of the transmission will damage the seal again.
The best is to use a transmission lift so you can know all the time that you stays in-line. Or to be vary vary careful at the matching.

Wishes you the best luck

it shows what you can do by your self, actualy it looks quite good.

Looks like a simple way to get it right.

Thanks for the advice.

That is a GREAT idea!!!

No prob.
all the credit should go to white90.

keep having fun out there.

as an aside I'd wager it is actually leaking from the intermediate gear shaft
there are 2 o rings that i've in and allow the oil oil
I put RTV over the end to stop it
a pic of this can be seen here:

to the left of the main shaft seal the RTV can be seen

It turned out to be the O ring seal - was torn when fitting the shaft and a small piece had been carried through to the gearbox seal allowing it to leak as well.

All fixed now and ready to head bush again.
