    Salisbury vs ENV diff

    hi all,

    toying with the idea of a locked salsbury in the rear of the jalopy rather than the env. Env makes me nervous as far as parts availability if required.

    question is will the width be the same as env? spring, shock brackets etc all bolt up.

    Thanks in advance for your input

    Cheers

    You won't get a locked centre for an ENV, but I don't know about a Salisbury. The spring mounts are in the same places on both lwb diffs, they're only different in swbs, all s1s except the 107 wagons, and 2B Forward Controls. Also, S1 axles are an inch or two narrower than S2-3. You'll need a prop shaft for the Salisbury, too, and make sure it's the right one (4 or 6cyl shafts are different lengths).

    Hope this is helpful.

    I have been considering exactly the same issue and both of us have SIIBs with the same dimensions. Getting any sort of locker or LSD diff for an ENV will be an expensive exercise. However there are a range of Detroit, ARB, Truetrak and various other lockers for the salisbury (which is basically a Dana made in England under licence).

    I am thinking that the County rear end is about the same width as the SIIB ENV and have recently acquired one, which convieniently has the same brakes as the SIIB. Using the track width of the County and comparing it with the specs of the SIIB will not help as both models have different width rims with different offsets and they may be the reason for the differences in the specified tracks. Will measure it up in the next couple of weeks.

    My plans are to remove the County 3.54:1 crownwheel, pinion and hemisphere and replace with a 4.7:1 crownwheel and pinion from a SIII 109 and build them up with most probably a detroit locker hemisphere into the County housing and Hi-Tough halfshafts. In the meantime, the plan is to fabricate spring mountings for the SIIB onto the county housing. Don't think that I want to go to coil sprung SIIB ATM.

    What is slowing me up is all the other things I have on my plate with Winter Rally, Eastern Creek Classic and All British Day this month.

    County and RRC axles are around 61" WMS-WMS. What is the measurement of a IIB diff???

    It would probably be a good idea to use halfshafts larger than 1.24" 24-spline (even in hi-tuff).

    If you buy a D60 locker/hemisphere you can use 1.31" 30-spline halfshafts - with no modification apart from a slight boring of the stub axles (in some cases). Places like Rovertracks can supply axles - HTE may be able to make them as well.

    If you want to get to or exceed FC101 levels of strength you can fit a 1.5" 35-spline D60 centre and halfshafts. However to do that you will need custom stub axles from JacMac.

    The difference between a Series 3 and a county Salisbury is 6" on the long side axle tube only. It may be just as easy to get a SIII axle modified for the extra width.

    Sorry IsuzuRover I am not familiar with the acronym "WMS"?

    I have not actually measured the drum face to drum face on an ENV rear assembly, but can probably do it this evening when I get home. What I can tell you is that the SIIB is 4" longer than a Series 2-3 axle assembly.

    Oliver1981 is running a Range Rover front end on his SIIB, so the track must be close.

    I don't know that I personally would be keen on machining out the inside of a regular stub axle, they are thin enough already and the SIIB weighs 2 ton unladen with a 1.5 ton payload rating.

    Currently the SIIB ENV uses standard Series stub axles, although to remove the ENV halfshafts you have to remove the stub axle and slide the halfshaft through from the inside as the ENV spline is too large.

    great stuff

    Thanks all for your useful responses.

    The front end in mine is county so I think a county rear might be the go with mods to the banjo to suit the springs....although a coil spring rear end might be exciting also.

    Diana, I'll be at the rally with garrcol so I'll look forward to having a chat about tout conveersion

    Cheers

    WMS = Wheel Mounting Surface

    Series IIAs are 55" WMS-WMS - so that makes a IIB 59"

    I wouldn't worry about the slight amount of machining. The tolerance on stub axle bores is quite wide. When a friend and I did a 30 spline conversion on his landie, we only had to machine 1 stub axle - by less than 0.010"

    I put Salisbury front and rear in my 2b. I got an engineering shop in Nambour to pull the long axle tube and replace it with a longer one to take the Maxi Drive locker and axle. Did much the same with the front. Put a Maxi in there plus went to coils as well. Only coils up front not rear.

    I think I saw your IIB back in 1998 at the 50th event at Mt Gravatt??? Very nicely set up.

    hi there!
    Well my 2B FC was one of them at Mt Gravatt in 1998. Its was the ser3 gold coloured one with the proto type 6x6 perentie tray on the back of it. Still got the beast though off the road atm as well as another 2B.
