Some of you are aware of my conversion, where I replaced the 4d56 (2.5TD) engine with a 3.2 Di-D diesel engine.

The conversion is a great success, except for the final drive gearing.

Currently I have 1:4.875 diff ratio, which is way to low for my application (90% on-road).

The Gen3 Di-D comes with 1:3.9 diffs, so I thought that would be about what I needed.



According to the Aussie site, the current diffs I have are as follows:

http://www.outerlimits4x4.com/PHP_M...amp;sid=5452dcf54a5c0d6ac448b1764b11cef5

Front: 7.25" dia (low pinion), 25 spline, 29mm diameter

Rear: 8" dia, 28 spline, 30.5mm diameter



I found this site, where they advertise 3.9 diffs for Monteros:

The problem is that the supplier cannot verify whether in fact it will fit my Pajero.

Does anybody have any info on the availability/suitabiliy of these 3.9 R&Ps?

it looks like you have the 4 cylender size axles.the 3.909 gears for the trucks should fit your rig.

Poweram,

1. Which trucks? Remember we had different Mitsu models here in South Africa.

2. How available are the parts from breakers? Ring & pinion only?

3. Price (I will pay for freight).

4. Would you have Mitsi part Numbers?

Thanks so far.

breakers?is this a junk yard?basicaly all 4x4 dodge d-50's and mitsubishi mighty max trucks with the 2.6 came with the 3.909 gears.i know there are a few in the junk yards around here.i am sure someone here has the mitsu part number.my truck had the 3.909 gears but i got rid of those when i got my 4.625 gears out of a monty.

PowerRam,

Sorry,

In USA = junk yard
In UK = breaker
In South Africa = scrap yard

How easy would it be for you to source two second hand sets of Ring & Pinions (front & back), and at what price?

Mitsu Part nos?

last i knew there was a couple junk yards that had them.i will call and see.

i just got off the phone with one place and they wanted 350 amarican for both and then there is another place that said he would give me a deal if i got both front and back.he said 200.

Powerram,

Sorry, I'm off air over weekends.

That sounds fantastic.

I will need front and read diffs' R&Ps.

Is there a way you can confirm that they are the sizes as per my original post? I would hate to pay for shipping etc. and find that they do not fit!

I am sure I can find a way of getting money to you once we can confirm that they will fit?

what year is your rig?

The Pajero is 1989 LWB (NG) of Japanese origin.

As I bought it:

Non-intercooled 2.5 TD engine (4d56)
Auto transmission
Leaf springs in rear
4:875 diff gears
