T-Case Fluid Level

[flint54]

Welcoming your opinions on how sensitive the transfer case is to fluid level.

The book calls for 1.4 liters. I put the fluid into my rebuilt, but not yet

installed case, and then held it at all angles while manually turning the

yoke to wet all the gears. In my haste, I failed to realize that without a DS

installed it would leak. I'm going to add fluid to about what I think spilled, but

if I wind up 1/10 of a liter off are there any consequences? I'm not fond of the

old "fill until it runs out the hole" method because of angle variation. Thoughts?

Fill it till it runs out of the hole! Hasn't failed myself or many other vehicles ive used this concept on.

:agree:

Copy, thanks. So it's not sensitive to small amount of excess fluid.

...and just to be sure...fill it until it runs out the TOP hole. You'll use a lot less fluid that way.

Filling it until it runs out the (top) fill hole is the correct way to do it, I have found listed capacities to not always be very accurate. Same procedure for axles and manual transmission.

Yes, as has also worked well for me on countless axles and MT's, but I was reminded of this by the

occaisonal "DO NOT OVERFILL" warnings on some devices, and wanted to be certain this was not

the case for NP242. Thanks.

The only thing that will happen if you overfill any manual box is that it will huff fluid out the breather to relieve itself.

But yeah filling to the top hole is just fine.
