Who is getting confused by all the MSA/LT230 conversion threads?

[Lotz-A-Landies]

The LT95 is a strong and reliable gearbox and it would be a great option if there were a 5 speed LT95. The transfer assembly is unique in Land Rover transfers as the hi-lo selection is on the intermediate shaft and it is that fact that makes the 6X6 drive possible.

Where it is a problem for conversion to the MSA, is that the LT95 is a one piece casting for the gearbox and tansfer housings. To adapt it to another gearbox you have to cut the gearbox housing off and then weld on a mounting plate plus make a transfer box input shaft and support it on bearings which usually means that you can't use the rear PTO because you now have a rear support bearing in situ.

The LT230 is stand alone, ready and waiting for whatever box you want to fit to it.

the threads have been quite entertaining, if for anything showing how little people actually Know. and other will little or building blocks of eng knowledge contribute some fanticy ideas, mixed in with some good idears.

Why would a LT95 tranfer be any better than an LT230 transfer?

Only the Perentie LT95 have the tapered roller bearings and they only come in one ratio. I have a greater choice of ratios with the LT230 and I don't need the 6x6 drive out the PTO hole.

Not quite true Diana, There are currently 2 off the shelf Perentie ratios, 0.996 and 1.113 which is in the RFSV's and if you have access to a good lathe you can fit any LT95 ratio you like just by machining the inside of the intermediate shaft hi range gear to accept the bearings. Would be the way to go for a Perentie 6X6. That way you could use an isuzu box, keep the 6X6 output, fit 3.54's all round and go 1.1 or 1.3 in the transfer.

Hi Brian

I will conceed the 1.113 ratio, but the LT230 has 6 different ratios from 1.667 down to 1.003 giving a much greater choice when choosing to match tyre sizes and engine performance.

In the LT95 you still have to machine off the gearbox housing and make a new input shaft before you do the adapter work to mate any other gearbox to the LT95. With the LT230 you start by making the adapter.

123rover5 - had a skim through your threads (and a few diversions to other interesting things) but couldn't quickly see any major write up using the LT95 on the MSA. Link? If not, then new thread maybe?

Did you find this one?

Once the Tbox is cut off its not welded to anything.
The front was trued up on the mill and its bolted to the rear flange of the fabricated housing.
Off the shelf male and female spline pieces were used.
The female shrunk and welded to a flange that bolted to the MSA output flange .
The male end drilled out and keyed onto the cut off front of the std Tbox mainshaft.
I have oil in the adapter housing so the splines are lubed all the time.

I think I like Keith's idea for a couple of reasons. First up, I have a spare LT95 kicking about and even if I don't want to cut this one up, finding another is cheap and easy. Also, Keith has field tested it for quite some time now in a vehicle that weighs well over twice what mine does, and then tows with it. If he hasn't broken anything, then I'm sure as **** not going to. Reliability is the main thing I'm looking for. This conversion also seems to be more straight forward - I could be wrong here, and it could just be Keith making it look straightforward.

The 0.996 ratio works with what I'm planning, so no issues there either.

How many KM have you done in it now Keith since the conversion?

Cheers - Gav.

Gav i used to have the same conversion with the lt95 except it had a turbo 700 infront of it, then infront of that i either had a holden v8 stroker with all the fruit or a 6.5l chev diesel, i really liked that conversion, but i think it ran a custom splined input gear as the turbo 700 output shaft was not modified and slid straight into it.
But a hell of a lot of work for the average schmo! (I bought mine done).

Not as many as we would have wished
A bit over 20,000 since the MSA was put in.
Here is a pic of the left over splined set.

Thats what I had in first when I built it. It was a Ritters conversion.
Mal Story put it together for me.
The T700 broke so I then put in the 4L80E or somesuch but could not keep it cool even with two coolers it sometimes boiled the oil.

Interesting. My conversion was made by Rovercentre in Skye, or choockshed motors as the locals would call it (was on an old choock farm), i had trouble with my first t700, then got it built properly, was great after that, but was just in a rangie, a little lighter than your😊
