TD5 130 extended cab diff info wanted

[disco63]

Hi All
I purchased a 2001 td5 130 extended cab a few weeks ago ( ex telstra?),just prior to going up the cape in my sons county.
Having sat in the drive for 7 weeks with only the odd trip to the shop and back.This is the first time i have had a chance to ask all the questions that have been rattling around in my head. Please see photos attached.Here we go!! Q1 Is the diff a P38? Q2 can anyone explain/elaborate on the diff bracing ,and why put it on the weakest diff (if it is a p38?) Q3 Why didn't they put a Salibury diff in . I understand that most/all defenders in 2001 use Salisbury diffs surely it is the crown wheel and pinion that is important , not just the bracing.Q4 Should i put Salibury in ? Q5 The clutch is extremely heavy ,is it a problem, or did they install a heavy duty clutch to the model.I have a shed load of more questions but that will do for now.Also some photos of our boat trailer and sons county.

This has been discussed a number of times now, a number of members have these ex-Telstra NT vehicles.

Yes, it is a braced and trussed up P38 diff.

Why ? Because some late Sals came through with undersized axle tubes, Telstra overloaded the utes and the drivers drove them like they stole them over less than ordinary tracks.

This all lead to pulling axle tubes out of the centres and sometimes cracking the cast centre too, the P38 style diff was already being fitted to the UK army Wolfs, so the fitting of a beefed up version was done here. It's also probably much easier to weld up the fabricated banjo housing than a cast centre and tubes too.

Hi Disco63. MY 130 is an Ex-Telstra extra cab . What Rick says is the case. Spudboy says the diff is a "Wolf" differential as per UK army specs. Mine has 290000 kms on it with no trouble. My clutch pressure is qute normal and is about as heavy as my BIL's twincab 130, so yours may not be typical. I am quite happy to answer any questions you may have, as far as my knowledge goes. Cheers, 130man.

thanks rick130 and 130man for the reply,any idea what ratio is in the diff. It feels quite a bit lower than my disco2 ,i'm guessing 4.1:1 or lower?
cheers David

it should be 3.54:1

the deefers have a lower tcase gearset than the discos.

[disco63]

Thanks blknight, i forgot about the transfer case ratio.The other question i have is.Are all the salisbury diffs the same width etc,and would it fit my 130 if coil spring platforms and trailing arm mounts and any other brackets are welded to the axle tube. Or do i need to source a salisbury from a later Defender to save the hassle.

Coil sprung Salisburys come in disc and drum brake versions, the leaf sprung Sals are narrower track, 4.7 ratio and all drum.
To get a disc sals you'll be looking post 1994 AFAIK.

The Salisbury in my Stage 1 Leaf Sprung Land Rover is 3.54:1
