Landcruiser- 2H to 4H

Ahh, just re-read; thought you meant H4 to L4. As above; any speed.

Oh god,,,noooooooooooooooo.
Not the twin stick...the horror, the horror of it all.
How could you even mention that gearbox,,,i'll be having nightmares for weeks.....:(:(

lol.

Fortunately my beer gut prevents me driving a B-series Mack without rubbing a hole in my shirt, so the problem is purely a hypothetical one these days.;-)))

Go the mighty 'R series'!

Hiya Doggy Tease Wooof Wooof!MPG:33!

Forgot to say - I normally use the clutch for H2/H4 shifts so that only the read prop shaft is driving the transfer case. Casper

Hi Cowpat,
There is no syncho on a landcruiser transfer case. WHat happens is that as long as you are not spinning wheels, or turning a hard corner, the front and back output shafts are spinning at the same speed. therefore the dog type engagement does not notice a thing. Better to be swift with your change though. If you try and change into 4H with the hubs unlocked you will get a good grind. H4 to N to L4 is better at stop or very slow, preferably stopped.
Yes you can change from 2H to 4H at any speed. What you are doing is sliding a sleeve with teeth in it over a shaft with splines in it. Once it is in it is in, if its out it is out. I have rebuilt tansfer cases from 40 series to 100 series including constant 4wd and they are all the same, minor difference for the constant 4wd.

Thanks Ray, I thought I'd got it the wrong way around, thanks. Casper

Had a look in my LC100 owner's manual...like V8Diesel said you can shift from L4 to H4 at any speed, just need to press in the cluch. Awesome.

H4 to L4 must be at stop or less than 8 kph; and H4/H2, H2/H4 at any speed can leave the clutch out.

I've seen what I thought was a synchro (yellow metal rings etc) in the part-time 80 series and 100 series transfer cases but totally misunderstood what it was for. Might not exist in the full-time boxes, I've had one of those apart but just can't for the life of me remember. I mixed up how the internals worked but now I have been enlightened! I'll be doing those twin stick upshifts (and loving it) from now on. Casper

Hi cowpat, don't know if I'd recommend low to high on the fly though as general operating procedure. I used to drive Landcruiser bush bashers full time as my job in mineral exploration and you get quite good after a while at operating that particular item of plant.

I'd take it up to max in 5th low, then clutch in and simultaneously go to hi range on the transfer and third or second on the gearbox. Toyota 10 speed.

You get pretty good at changing flats and fixing split rims too (10 per day). Two person lifts of full, heavy duty galvanised 44 gallon drums on to tray back 75 series Cruisers as well. (that's why I'm so busted up nowdays)
