LT230 transfer advice

[outlaw]

Okay unfortunately my transfer has been cooked so need a replacement... it is in a '96 fender running 33's (thinking maybe going 35's).

What advice can you offer... as with most here, I am strapped for cash... currently been quoted 3500 installed for a new one (supposedly) but a bit wary as the price seems to cheap.

Any suggestions on what i can do cheaply (but still strong) to help with ratios etc for better low & high?

So the 3.32:1 low isn't low enough?

A decent 2nd hand t-case is only $500 from a wreckers.

But the best option would be to get yours rebuilt, and in the process fitted with either of the MD low range gearsets. The gearsets are about $1900 I recall. So that and a box rebuild should easily be possible for $3500.

Yea but his high range will be screwed with a second handy, as you won't get a defender transfer for 500, If you can let me know, but i've seen them sold for 1500

[Reddo]

too true cloughy - priced one in Tas, last year, had been sitting in the wrecked vehicle in the open for gawd knows how long, may be 5 years or so, and he wanted 1800 for it!!! He knew too much about them....

so there are different ratios in lt230 cases depending on vehicle?

Low range is the same in all. High range varied with vehicle. 1.41:1 in Tdi defenders, anywhere from 1.003:1 to 1.22:1 in the rest. (there was also a 1.67:1 but this was in the 2.5P/D 110/90s which didn't make it to OZ).

Ben,
Actually, the 2.5 Petrol came with 1.4:1, it was only the 2.25/2.5 diesel that came with the 1.6:1. Also, isn't there a 0.9:1 that was used in the autos? I remember a friend of mine put them in a Range Rover with a 4BD1T and LT85, when the motor was cold he needed low range to get out of his friends drive way!

Thanks for clearing that up.

AFAIK the tallest LT230 ratio is 1.003:1 - was fitted to OZ 110s with 4BD1/LT85 and "high compression" rangies (auto and manual ?).

Tallest LT95 ratio is 0.998:1 - again fitted to some rangies and 4BD1 diesels.

The 1.003:1 LT230 was fitted to torqueflight equipped rangies

I've got one of those, they are the LT230R with roller bearings and mine dates from 1983. Later LT230T's with taper rollers are supposedly better but I'm not sure in what way.

Got a TF727 going cheap if anyone wants one.

Okay so any recommendations on who can do a rebuild with MD gears around GC & brisbane?

Options (not Recommendations)
Mini Automotive
FWD Motors
MR Automotive
Rovertech?

[uninformed]

recommend RICKS 4WD, Nerang, gold coast

they do all my def servicing etc.

I had mine done thru MR automotive.
They also machine out the outputs and steel sleeve them to stop the output flanges becoming sloppy. I supplied the single piece cross shaft from jac macs and they supplied pretty much the whole internals as they were all to far gone from the last centre diff going south. They were pretty good on price as well. I think it was about $1400. Not to bad since everything was pretty much new.

Sounds pretty good - $1400 + $1700 for MD gears. A mate mentioned he had his defender T-case rebuilt by MR as well, can't remember how much but he was happy.

[evanstaniland]

if yoy go to look at a LT230 how can you tell the differance between the ones that come out of a disco and the ones that come out of a defender???

im looking at one a which has HRC 42 stamped on the back of it but it doesnt ring any bells!!

also what kind of reduction do the MD gears have and where would i inquire about them???

Evan..

[red90]

The regular MD gears are 4.34:1

There should be a sticker on the back with the high range ratio.

[evanstaniland]

with the maxi drive reduction gears am i correct saying that the kit will replace all the gearing inside the case so if i was to put the MD reduction gears in it wouldn't matter if i got a case with 1.4:1 or 1.003:1 standard gearing???

please shed some light!!

Evan..

[red90]

No, it just replaces the low range gears.

They just might be better 'cause they use tapered roller bearings on the intermediate shaft

Shipping may be a little dear

Thanks for that "captain obvious".
I'm more worried about functional differences.

Your welcome

Functional differences??? they just run tapered roller bearing in the intermediate gearset, allowing for a preload, instead of shitting the little needle rollers

[uninformed]

Maxi-drive have 2 differnent low range gear sets

30% lower = 4.316 - 1
49% lower = 4.9468 - 1

So what's the usual timeframe before a R box starts to give trouble? Mine was secondhand and in unknown condition. It has a quiet whistle/whine that sounds a little like a boost leak.
Is it possible to swap the high ratio gearsets across from the 1.003:1 R box to the 1.2:1 T box?

I guess since anything is possible, how many parts will I need to modify or make?

[Reddo]

Whine in 5th gear is normal as far as I know, and can be made worse by the gear stick and boot/tunnel sealing arrangements. Just turn up the stereo!

[bushy555]

Got hi range: 1.2:1 ratio with 30% maxi rock crawler LT230RC (rock crawler. I love saying that). Whine in 5th is really sweet (and loud) Welp, I love the whine anyway. I try not to do it too much - reckon it might overload everything a bit too much.

Difference between defender and disco transfers is pretty much easiest to tell from the serial number. Got heaps of info somewhere laying around.... PM me if ya want the ifo. I'll have to go looking for it.
Just sux when serial numbers are grounded off.

The whine (more of a whistle) is there in all gears from about 30km/h up. I don't have a rover gearbox either, but the noise wasn't there in the 1.2:1 LT230 I swapped out.

[evanstaniland]

i have another question roughly how much would a LT230 out of a 300tdi weigh???

Cheers

The same as an LT230 from a V8i














Dunno bout' 100kilo

100kgs...*cough* are you sure...i would say closer to 50kgs....
