Outer Limits 4x4 Board

g'day all,
Have just bought oil to do a change in the gearbox / transfer on my 4 speed manual '81'model 40 series. Have the gregories manual but it doesnt show a pic of my gearbox / transfer, only the early models and the 5 speed. These may be blatantly obvious questions for some so excuse my ignorance lol. Now i presumethat the drain plug is on the bottom somewhere. And have worked out that the filler for the gearbox is on the left hand side somewhere. Now how the hell do you get the bottle up there to fill it up?? I have heard you can take the top cover off and fill it from here? it that correct? Also cannot find the drain or the filler for the transfer case?? Has anyone done this before on their shorty and can help me out????

Thanks in advance,


Adam

You can buy a pump that i used when i first did it, or there is another way but do you have a compressor

For a faster way, remove your transmission cover from inside the vehicle and unbolt the gearstick top plate then pour the oil in. Provided that all the bolts come out easily, otherwise you'll be pumping for a good 15mins.

Thanks guys, that solves the gearbox. bj, i do have a vehicle mounted compressor, very interested in how you would hook this up?? Also any idea on the transfer case???

cheers, ads

transfer case similar deal matey.

while you have the filler plugs out why not do yourself a favour and get one of those oil bypass hoses (im about to invest in one)
you hook them up to both filler plugs so the oil doesnt get stuck in one box after going up or down a hill.
its a common problem in this model cruiser box.

i noticed once i changed the oil and i think it was the gbox but anyways one of them had heaps of oil. the other was rather struggling. i undid the filler first to make sure i was sweet and bam out it poured!

filler on transfer on back of tcase half way up

personally i find pumping easier than pullin the gearstick cover.

Yeah, so do actually, I find it find it easier to get an old bottle with a long hole and get the old man to squeeze the oil down from the outside of the 4wd while you (or he) holds the tube into either of the box’s.

i borrowed agreat pump that screws onto th big tubs of gear oil, you crank a handle and it fills the diffs in about 30 seconds.

I think this is what you mean.

I have used this many times on the 75, however last time I put a bottle of that Lucas oil improver in the gearbox & it took over 1hr it to drain the 1L lucas bottle.

That stuff is super sticky, but makes a massive difference to the gearbox. Quieter, better shifting (especially when cold) & I beleive that I get better fuel economy. I am now down to 11.4L/100kms

I now use it in my engine, gearbox, transfer & diffs.

If yor use a bottle 4L one insert a tube tightly through the lid to the bottom of the bottle, insert air hose in container and pressurerise container and the fluid piss's out of the tube, takes about 20 - 30 second not 15mins

Excuse my ignorance, but can we have a demonstration of this...

I have a compressor, and I HATE pumping the oil into the POS...
Or can you buy a little unit to do this aswell?

Note the tube and air hose need to have a fairly good seal and not a lot of air pressurisation is needed

Can you make me one.

Thanks for the replys guys, i ended up buying an elcheapo hand pump from supercheap. (looks like the ones off the liquid soap dispensers but giant sized) Worked well for the 1st 1.5lt then it started to sh!t its self, go the job done though. Next time i'll give the compressor idea a shot

Cheers again,
