I have just encountered the problem of oil migrating from my transfer case to gearbox on my 95 Troopie. I read on one of the archived forums that a hose can be fitted between the two, to allow oil to drain back to the transfer case. One gent mentioned that these hoses can be purchased on Ebay. I have searched with all kinds of key words, but have had no success at tracking down a hose kit.
Can anyone help me out... Gonzstort

Gonzstort.

I had one made up by Pirtek. I have heard that Enzed will also make them up.

Gday,
Yeah...as said above Enzed, Pirtek or any hose doctor type mob will make them up. I think you might even be able to get them from toyota.

have a look through ebay under landcruiser and when you see the water tanks for sale, pm him (hobsee) and ask him if he has one....he should.
If you want to do it through the hose doctor or Enzed, get two 3/8 bsp duffield nipples and half meter (measure yourself what the right size will be) of 3/8 hose with 90 degree ends. It is not exactly the right thread for the filler threads, but it is real close, some teflon tape is all i used to seal it properly.

G`day,
Just pointing out the obvious, make sure that it is "hitched" well up out of the way of any "snag" if going off the black top.
Potential for a disaster if it got hooked on something and lost gear box and transmission oil.

I had an HJ45 years ago with one fitted and was involved in a lot of off road ( as in across paddocks , bush etc ) work, I was always concerned about it getting snagged without me knowing.

Cheers

I don`t know where i`m going but i`m enjoying the journey.

The transfer hose is only treating the problem and not fixing the fault. And the fault is easier than fitting the hose. The problem is that the rear seal on the main gearbox is only designed to stop oil going into the transfer case. Now to the problem on top of your transfer case there is a small breather that is not easy to see but you can feel it near to where the transfer case bolts to the main box. As the transfer case heats up and breather is blocked it forces the oil up and pushes the seal lip on the main gearbox in and oil is pushed trough to the main box. That is why your main box is always overfull and the transfer is low. By cleaning the breather it will fix the problem.

Hope this helps

is that likely to be the same on a Hilux (LN106)? I lose about a litre of oil every year from the TC into the GB.
And if that is possible does that TC breather you mentioned have room to fit a piece of hose to extend the breather up into the cab in case of deep water crossing?
cheers

Your theory would not have held water with my HJ45 as it had extended breathers up into the engine bay near the brake reservoir, and it still transferred oil. A mechanic at the time said the action of the output shaft actually pumps the oil forward once the seal wears.

The HJ 45 would have a 4 speed gearbox and used a different transfer. And your mechanic is half right, the 4 speed gearboxes had a bad habit of the output shaft nut on the main box (not the transfer case output nut which you can see when you drop your tail shaft) of coming loose and let the two main gears float and wear the shaft and yes they would false oil through the seal. But this a fault that needs to be repaired not band aid fixed by putting a transfer hose on it. Some years ago we started fitting a different rear output seal in the main box with a double lip seal out of a automatic gearbox which fixed the oil transfer in to the main gearbox but blew the rear seal out of the transfer case, this idea was short lived. We now fit a small elbow on the pressed steel cover plate that cover's the PTO mount and extend the breather up under the bonnet. At the end of the day you will do what works for you.

Thanks for the info, I now have a standard 100 series 1HZ, do you think that this t/case will need any mods like a better breather?

Hi Mike, your 100 series will not transfer oil as the two gearboxes are now separate and have a drain hole in the adaptor case that will indicate if there are any faults with seals.
And I believe that breathers on your gearboxes and your diffs is one of the best mods that you can do on any 4wds. For the small outlay it could save thousands of dollars.
And with the floods that you guy's are dealing with now in your lovely state there would be no better time to fit your breathers.

All the Best

Thanks Lee,
I have fitted breathers running up to the engine bay. Like you I think they are very important.
