Diff And Transmission Breathers on a Diesel KJ - anyone extended the tubes?

[Wilmo]

Hi All,

I just grabbed these pics out of the parts manual for the 05 KJ, they show the diff/tranny breathers for an 05 CRD KJ. Just wondering has anyone tried to extend these up to the Engine bay to make water crossing less troublesome?

Front Diff Breather




5 speed Auto Transmission (Note: this is the 5 speed that comes with the CRD - see pic below for the 4 speed used on the 6 Cylinder Petrol 3.7L KJ)




4 speed Auto Transmission (This is the 3.7 Petrol Engine Tranny!)




Rear Diff/Axle (the parts list shows a Corp 8.25 but shows leaf suspension if you look at the pics.....right axle, wrong suspension -doh!)



Rear axle breather close up




Selec-Trac Transfer Case



The red circles show the breathers and attachment points.

I was considering buying some 5/16 fuel resistant hose and joiners and extending the tubes up to the rear of the engine bay to stop water ingress into the diffs.....they are pretty low to the ground in stock form. Anyone done this?

Cheers

Wilmo

Also, found this info on L.O.S.T for those of you that want to know.....

The front diff breather is under the battery tray. Kinda high. Easily extended.

The transfer case diff is run ALL THE WAY to the auto tranny's dipstick tube. VERY HIGH.

The rear diff is run up to the gas tank area. Kinda high. Easily extended.

The tranny breather is behind the engine right underneath the [passenger side in Aust] head. You can't see if from the top, but you can easily get a hand to it. Just need to crawl on top of the engine a bit. Pull out the little spash gard. Slip in a [tube joiner] already connected to a longer piece of hose and it is done.

I'll try and verify if this is all correct and report back.

thanks

i took the battery tray out over the weekend and was wondering where the tube went

I found all the breathers tonight, two of them are on top of the bell housing for the tranny, squeezed between the gap in the body and the bell housing (tranny and transfer case breathers), both accessable just enought to push a connector into once you remove the plastic valve on the end.

The transfer case one is accessable from under the car on the passenger side, the tranny one is accessable from the drivers side of the engine compartment, its down next to where the tranny dipstick tube disappears under the firewall.

You have to hunt around a bit under the car to feel the 5/16 rubber hose that could be only these breathers.....both are plugged with a white plastic valve. They seem easy enough to extend with a bit of fiddling around with connectors and tubes.

The rear diff is easy to spot, and looks like you could add a length of hose to it and direct it up through the chassis rail to the petrol filler area. The front diff is under the battery cover as Fouros found.

Interesting pics from the manual, one of the pics shows leaf springs?? Must be the US model?
