Re: Who's running an LT230 and permanent 4x4?

yes i did try Traceys 88" out, just a little trundle round the
carpark to see what all the fuss was about the permanent 4x4
with Series axles, i found it really nice to drive although i
wouldn't class it as a "proper" test
i now have a short bellhousing LT77 (with tired tailshaft) sat
on the floor of my garage, a 1.4:1 LT230 sitting in another
corner (will probably look for a 1.2:1 though) for a future
tinker/swap into my 88" bitsa when i find the rest of the bits

I think there can be nought to gained but trouble by bolting
metalwork that has no place where perfectly fit for purpose
engineering belongs.
What Birmingham fitted Birmingham can know still remains in my
Land Rovers.

Worth considering that unless it's a Stage 1 Salisbury it will
be 4.7:1 ratio rather than the 3.54 that your LT85/LT230 would
have driven originally, so you may find it runs out of legs
sooner.

Rover Miner - I take your point, but for me the original engine
and gearbox are only marginally 'fit for purpose' in the modern
world.
Perfectly adequate for most off-road situations and trundling
down B roads, but even with the overdrive I struggle seeing much
more than 65MPH.
I would like to be able to tow my TVR to track days and such at
some point on the motorway - something I wouldn't dare do with
the current engine.
I don't wish to open up a can of worms here, but the series III
gearbox is a fragile link in an otherwise very sturdy vehicle.
The engine has to come out at some point anyway as it's leaking
from the rear main seal, has worn valve guides etc.
If I was sensible, I'd sell the vehicle and by a debender, but
they don't have the character of a series, and I'm very attached
to this particular Landy.
Doug_T: Thanks for that nugget of info - I'll do some
calculations.
I gather that the LT230 used in the Chrysler Auto Range Rover
Classics was a very high ratio box - could be worth hunting one
out.

1.003:1 - but you'd probably find it easier to locate a
Salisbury from a boingy and swap the internals with your current
one following Eastwood's "how to" guide on here somewhere.
However if you did find a 1.003:1 LT230 and kept your 4.7:1 diff
ratios, then you should have mega-low gearing in low range.

If at-all possible, swap the diffs rather than the transfer box
to get higher ratios.
Running taller diff ratios means slower propshafts - I was quite
surprised when I first put a high ratio diff in Bitsa how much
smoother everything got, and I think a lot of that is just down
to the propshafts spinning slower.
I've been running a rear salisbury axle for several years (and
mega miles) in 2wd behind a tdi and the only problems I've ever
had have been stripped drive flanges (known wear issue that
gives loads of warning before failure as you get more and more
backlash between power and overrun) and a diff cover that
pinholed, let all the oil out and consequently wrecked the diff.
I'm not known for being gentle on the driveline either.
Ultimately it's your call, but it's pretty simple to convert an
lt230 to 2wd and it does make for much more fun drifting round
roundabouts...

Lt 85, 230 and Dana- they are in J20 jeeps which are 2 tonne and
history of large v8.
