    Yours must have been the one with the big canvas canopy?

    Sorry about bumping the thread......

    Can somebody summarise the differences between the FC Salisbury axles and the axles found in a Series 2/3 109?

    - is it a given that the FCs had Salisburies fitted front AND rear (let's disregard ENV axles)?
    - the diff ratio (CW&P) is the same between FC and a normal Series: 4.7:1?
    - WMS differences?
    - were Salisbury front axles fitted to any other models ?(I understand that some South African CKD versions might have had them)
    - If I want to convert a Salisbury front diff to 3.54 ratio, can I use a 110 center portion or CW&P? Surely the CW&P would need to be reverse cut?
    - brake differences between the FC Salisburies and the "standard" Salisburies?
    - how much of an issue to upgrade to later axle shafts?

    thanks

    South African built CKD IIB's had Salisburys front and rear.
    As far as I'm aware all the IIB FC's that came out of Solihull had ENV axles front and rear.

    The main difference between the FC axles and those fitted to 109 as fitted on One Ton models from about 72-76, along with other Heavy Duty applications such as armoured cars.
    All were fitted with the 3 inch shoes and 11 inch drums on the front, and standard six cylinder brakes (2 inch shoes and 11 inch drums) on the rear.

    All leaf spring Land Rovers (apart from the 101) had 4.7:1 diffs, the 101 had 5.54:1 diffs.
    If you want to swop a 3.54:1 diff from a coil sprung axle into a series one it is possible. You need to swop the entire diff carrier (everything that comes out when you undo the bearing caps) along with the diff pinion, which requires a new crush tube between the bearings.
    101 and Series Crownwheel and pinion are interchangeable without the diff carrier.

    No need for reverse cut gears, the factory didn't bother.

    That covers most of your questions.

    The One Ton Salisbury front differential assemblies differ in that they have the standard narrower Series 2A/3 track width matching the rear Salisbury differential introduced in the last of the Series 2As. Unlike the wider Salisbury 2B front ends with removable swivel balls they have integral swivel balls like a 101 front Salisbury. "E" suffix 2B Forward Control ENV hubs also have 16mm wheel studs rather than 9/16 BSF.

    We used to replace the crush tubes with solid spacers (need a bit of fiddling to get it right) so that pinion seals could be more easily replaced and still retain the correct preload for the pinion bearings.

    The SIII Stage 1 V8 (and Isuzu in Australia) was leaf spring and had 3.54:1 diff ratios, however the pinion angle on the front diff is inclined so should have a DC jointed prop shaft. The front assembly also has CV joints in the swivels.

    AFAIK only the last contract of the South African SIIB had the Salisbury diffs. This was because SIIA/SIIB and ENV production had ceased in the UK. SADF called their 1974 build SIIB: SIII I Ton, 110" F/C they also have SIII clamshell design chassis.

    The earlier Sth Africa built forward control (prior to 1971) had ENV diffs. In Australia some very late SIIB (sold to ACT) were fitted with Salisbury diffs. Even as late as July 1973, all the NSW records of SIIB are 331 prefix up to D suffix vehicles indicating UK build. The Port Elizabeth build SIIB with Salisbury are 332 prefix with F suffix. Presumably the Salisbury assemblies were manufactured in the UK and shipped to Port Elizabeth, so whether these last ACT vehicles were 332/F or 331/F is unknown and were likely sold through Leyland Truck and Bus, where we don't have the records.

    FWIW - since it sounds like Jake is thinking of retrofitting...
    I have a Stage 1 complete front axle in my IIA, with standard IIA propshaft (unis out of phase). I have no front end/driveline vibration whatsoever.

    If you do retrofit, I would use a standard 110 or Defender rear Salisbury with drum brakes and retrofit the spring and shock mounts. Make your Salisbury front to match the Defender track, probably using another Defender or 110 housing and then use Stage 1 CV swivels which will leave your steering and front brakes unchanged. IIRC the Defender/RRc is 60mm wider than the SIIB.

    Barry Ward, Hi-Tough Engineering (Maxidrive axles) in Queensland has the brooches to cut the stage 1 CV and Salisbury diff splines in halfshafts for your project.

    However if you're thinking of going disk brakes, then use a rear disk brake Defender Salisbury and PM me about the front disk options.[/I]

    I'm looking at fitting the FC axles to a Series 3 109 ute.

    If the track widths are different between FC Sals and standard Series Sals then I'll need to fit a pair and deal with the extra track width.

    Then I might need to compensate for the 4.7 ratio at some stage, so hence the question regarding the later diff center portion interchangeability, but I wasn't sure if there were axle shaft differences : size and spline , between the FC Sals and the later 110 Sals.

    The SIIB assemblies are 4" wider than the standard normal control Land Rover, (SIIA are the same track as normal control and that's why they fall over) The SIIB are also underslung rear axle assemblies so you will need to swap the spring plate to the underside.

    If you are only looking at having a Salisbury front end with the original track, then the early SIII 1 Ton Land Rovers had a front Sals, but these were discontinued before the end of the model and many later vehicles only had standard Rover diffs. You would need to watch the for sale and ebay ads in the UK to get a front Sals and they occasionally come up in vendors like Blanchards and Dunsfolds.

    You are in the correct place to find SIIB f/c Salisburuies.

    Diana says above that FC (IIB I assume) axles are 4" wider than series. Coiler axles are 6" wider - HOWEVER a rear coil sals only has the long side axle tube lengthened. The short side axle tube and axle are the same length on both 109" and drum braked 110 salisburies. So it would probably be easiest for the rear to widen one side of your 109 sals and buy 1 custom axle (halfshaft).
