Is a Salisbury a Salisbury

[roverrescue]

Is a rear Salsbury diff from a Series III the same as a 1995 130 fender.

Obviously the axle tubes etc are different, and the axles are different lengths
but is the actual differential the same.

I can pick up a complete series III axle with maxidrive locker for a price that is hard to sneeze at. I already have maxidrive axles (with locking splines on short shaft) in my sals. Will I be able to weld on an actuator bracket to my housing, bolt entire diff up to my housing and be locked?

I guess the pertinent questions are:

Are they the same ratio?
Do they accept the same size axle (spline and root diameter)?
Is the actual diff housing the same?

Short answer is no - they are different

Long answer is that there are 2 different flange positions for the diff centre of the salisbury (and Dana 60) - 4.5:1-7.17:1 ratios have 1 flange position and 3.54:1-4.3:1 have another.

Since the locking dog mates with the half of the hemisphere with the flange, the series locker is no good to you unless you want to run a ratio between 4.56 and 7.17, (e.g. 4.7:1 like the series does)

110 is 3.54:1, series is 4.7:1
Other than the ratio and flange differences they are both the same. County salisburies actually have the same length short side axle tube (and axle) to series.
Coiller housings of course have different suspension mounts though.

I'me confused, the salisbury houesing are the same (except for the coil and leaf) suspension mounts....I would have thought you would have been able to swop CWP, to the serries center without any problem....what flange positions are you talking about??

The flange that the crownwheel bolts to.

The same goes for a rover 4.7 and 3.54 diff. You can bolt a 4.7 CW to a 3.54 centre with a spacer, but not the other way around.

OK the hemispher, bugger I thought all the centers were the same, just differant CWP ratios, I will have to go an have a look....lean something new every day.....:)

I already have maxidrive axles (with locking splines on short shaft) in my sals.

I think you mean locking splines on the LONG shaft??? Unless you somehow have a rover axle fitted to your sals?

Both Series and county/defender MD lockers had the locking dog on the long-side axle (engaging to the half of the hemisphere with the crownwheel). Rover rears had the locking dog on the short side though.

Good point on locking splines... was thinking back to rover axle i had on the disco.
Either way I know I have lockable maxi axles, but it seems that converting the series sals to 130 aint gonna happen. So, I will then let all know series III rear axle assembly including maxi-drive locker - $500, located in Cairns. PM and Ill get the guys number for you.

I read somewhere or other that for the coiler Salisbury diff, Land Rover changed the 24-spline side gears to a different 24-spline. No, I don't know how or what or why, just a reference to it departing from the SAE standard for that size spline. I don't know it it's true, but thought I should mention it.

NO - the 24spl is the same on series and coiller sals axles.

I think you are confused with the defference between Sals/rover 24 spline. According to Mal Story, when the Rover diffs got 24 spline side gears, they used a non SAE pressure angle etc...

Mal said he made all his (rover) lockers with the salisbury (SAE) 24 spline dimensions.

NEW INFORMATION ????

Am I to understand that in the County models the Salisbury is more offset to the RHS (i.e. Not in line with the output on the transfercase) and that the prop shaft runs at an angle to the RHS?

if anyone is looking for a maxi drive salisbury hemisphere Crown wheel carrier (from a series 3) that has a 3.54 ratio crown wheel and pinion please give me a call as i have one here.It fits straight into the Defender salisbury axle.I had it in a series 3 that I converted to 3.54 ratio a few years ago.The centre was modified by Mal Storey at Maxi Drive and the crown wheel was machined to fit into the housing with the larger 3.54 pinion. I have used the vacuum cylinder in my 110 but i still have the diff centre with the maxi drive splines and the locking dog here if anyone is interested in it.

I'll vouch for dealing with Brian, the man is fantastic to deal with:)

Bugger - just bought an ARB for my 110...

Pretty much, but the same does for all 110 models, not just the county.

When Land rover built the 110, I think they took the easiest path and moved the whole axle 3" to the drivers side, and extended the long axle tube/axle by 6". (values are approximate).

When the Defender changed from drums to discs, narrower bearing spacing hubs were also fitted, which meant that both axles were shortened by 10-15 mm.
