Join LCOOL and ask there but do a search on there as its been covered endlessly.

You will probably find full instructions as well

If it's to balance the oil between boxes due to a leaking seal you can buy the fitting already made up.

One of the simplest connections I saw done on a 40 series landcruiser. He just took out the box filler plugs, threaded them and screwed in a barbed hose connection.

Once the plugs were in a length of fuel hose was then pushed onto the barbs and hose clamped in place.

It was probably the easiest way to do it and no risk of swarf getting into the boxes as it was mostly done in a vice on the bench.

Or you could do it with hydraulic fittings: It would look neater and less likely to get torn off.

What I did on my previous Cruiser gearbox (H55f) to transfer case mod was to buy 2 banjo bolts with from memory, 14 mm thread, the same as the original filler/level plugs.
These screw through 2 appropriate size banjo fittings with tails that a piece of fuel or low pressure hydraulic hose was pushed onto. All the fittings and hose should be available from any hydraulic hose outlet such as Hoseco, Enzed etc. Virtually no pressure so as long as the hose can handle diesel fuel or oil nothing fancy is needed. The advantage of using a banjo setup is that the whole thing sits closer to the transfer case so not as likely to get caught by a stick or whatever.

If I remember correctly the 80 series had the heavier duty H150f or H151f gearboxes and the sizes may be different. Just my observations, but I didn't think these boxes had the same problem of the transfer case oil being pumped into the gearbox through the common oil seal as with these later gearboxes and transfer cases there was 2 separate seals one for each with a drain hole passage between. If either seal leaked (uncommon) the oil ran out onto the ground.
I can't remember if the 80's with the 1HZ engine used the earlier H55f though.

Hope that helps a bit

Cheers

One thing I did assume, we are talking about a manual transmission not an auto????

You only need to do this if your gear box is overfilling with oil from the transfer case due to a failed oil seal. I just went to Enzed and asked, they knew exactly what I needed. That was on a 1979 FJ45. I understood the newer vehicles had better seals and this no longer happened.

My ute is a 1991 HZJ75 model and has the hose installed. Not sure when the better seals came into play.

You can buy a fitted hose from East Coast 4WD and wreckers.

DO NOT do this, as it was a fix for the 60 series which was 1 box seperated by a seal...the 80 series is 2 seperate boxes, and one will run low, one high if you do
b4 you bag me out, walk a mile in my shoes, then your a mile away and have my shoes :)

Spot on
gearbox and transfer are separated by an air gap
hose will serve no purpose
