central diff lock in high gear (HDJ80-24V)

Hi,
does anybody know how the modification regarding locking the central
differential in high gear can be done - I'm quite sure it can be done
since when you put in low it is automatically turned on (and ABS off) -
so the wires should be there ...
Thanks in advance for your help.
Best regards,
Tomaz

Hi Michael,
If you are lucky you can find them on Rav 4s - just need to find a
scrapped one!

Guys
Is centre diff in high gear a good idea?
If it was surely it would be standard capability.
More liable to break something bombing down the track with the CD
engaged in high gear?
Niall
 
Hi Niall,
I think it is ... but of course on the rough tracks or sand - definitely
not on highway.
On KZJ95 (prado, colorado) there is in addition to H and L also HL which
uses higher gears then L but with central diff locked and it is
recommended (in the car manual) for off-road etc...
regards,
Tomaz
 
Alright Tomas
Had my HDJ80-24V in Morocco - lots of dune driving, stoney desert and
deep sand tracks. Was loaded heavy as my buddies Landrover calved in
Spain and they jumped on board the Cruiser.
Didn't have to engage any diffs at any stage - just cruised along no
bother.
I rekon once you're at high range speed the requirement for diffs being
engaged is minimal - in most cases - but i'm no expert.
Also - would it not impeed ability to steer the vehicle around
corners?
Cheers
Niall
 
Hi Niall,
since I just recently switched to hdj80 all my experiences are based on
kzj95 and in that case the HL with central diff locked was very useful -
tho control of the car off-road was better - but hdj80 is a different
animal ... the gears are different and maybe it is not that useful.
regarding the corners - you are right but still drivable ...
Regards,
Tomaz

There's an interesting entry on the 80s-cool technical pages which says
that if you:
- engage the CDL, which automatically switches off ABS
- then exceed 70kph for at least 200m
The ABS stays switched off until you turn off the ignition and restart
the engine. The thinking is that on loose surfaces and snow you are
better off without ABS, and this is a good way of disabling it.
See http://www.lcool.org/technical/80_series/abs.html
No, I haven't tried it! I installed a diff-lock switch so that I could
turn if off when in low range - dead useful for towing and reversing on
tarmac - not turn it on in high.

Stopping distances on gravel with ABS engaged is far greater than with
it dis-engaged. I've experienced this on a defensive driving coures in
Australia.
Cheers
Niall
 
Has anyone ever looked in to the possibility of putting in a switch to
dis-able ABS?

Oh hello the Clive this is so easy for any body to do. Any capteur on
the road wheel can have it's wire put with a switch on it. Voila press
the switch and she ABS is in default.

I've experienced it on bumpy "tarmac" roads in Devon! If the wheel is
airborne the ABS gets kittens and you don't stop.
99% of the time I'd rather not have ABS, trouble is the other 1% it
might save your bacon.

Hi Niall,
I have used it occasionaly when driving across muddy fields and I have
started to slow and I also engage it when very icey/snowy - it just
helps keep you in a straight line.
I also used it a couple of times in the dunes in Morocco, although once
I had lowered the tyre pressures it wasn't required.

| Please what does that mean?
"Having kittens" (=3D giving birth to baby cats) is yet another English
expression. It means getting very excited and/or upset about something.
At the time I was driving down a steep hill on a narrow "road" near
here, and someone was coming the other way, so I wanted to slow down and
pull in to the left.
However the road was so rough that my left wheels were bouncing up and
down, and when they were in the air the brakes stopped them turning. So
the ABS thought "the left side of the car is skidding" and starting
doing its butt-cheeks thing.
So we just kept on rolling downhill with the ABS farting away, taking
about an extra 50 metres to stop. I was not happy!

Chris, I though by now we would have a butt cheek analogy ready. No perhaps
we don't want one linked to ABS and stopping.

I thought butt cheeks and the noise made by ABS made quite a good
association, but I'm happy to defer to your linguistic and/or mechanical
preference...
