ive bought/am buying a project that has these fitted. im trying to get some info on them, but it seems theres an awful lot of rumour and internet untruths about these axles out there, plus the van certianly had a bit of an identity crisis over the years, so tracking down what parts fit what can be tricky. so i thought we could maybe try to pin down the facts all in one place?
first internet truths i think i can debunk- at no time where they ever the same as a salisbury axle, or a landrover one. i believe the correct designation is a BMC C-type axle, and it wasnt fitted to any other vehicle.
first, dimensions. do they only come in one width, and if so what is it, hub face to hub face.
bolt pattern is 5x5". this mean you can get your hands on solid steels in 15"(sherpa), 16"(taxi), and 17"(early rover) quite easily.
ratios, i believe theres two available, 4.7:1 and 3.9:1?
power rating- it seems people run these on cars up to 300bhp with no problems?
next, rear brakes. from what i can gather, all single wheel models should use this brake drum. if you know of a different size one, let me know!
these are to fit the rear axle of single wheel variants-
Internal Diameter 228mm
Overall Height 84mm
Braking Surface 56mm
to fit vehicles-
LDV 200 Series- 1985 - 1994
LDV 300 Series- 1985 - 1989
LDV Pilot- 1994 onwards
LDV Sherpa 200/300- 1980 - 1985
the rear brake slave cylinders are 20.3mm bore, and are sided.
the shoes are a bit of an issue as theres at least 3 different types listed, but all with the same diameter, thickness and slave cyl, so it must be the handbrake mech or mounting hardware that differentiates them?
front brakes and spindles- what year did they go from drum to disc?
for discs, i believe theres two types. solid disc for full production period, then a vented disc came in in 84, for v8 equipped models.
solid disc- 276mm X 14.3mm, total height 53mm
pads for solid- 105mm long, 75mm tall, 18mm thick.
vented-275mm X 24mm total height 63mm
pads for vented-126mm long, 71.2mm tall, 18mm thick.
i know that there's at least 3 different types of master cyl for the braking system, two 2-pipe ones, and a 3-pipe one.
please add your experiences with axles on this thread, in the hope it will help other rodders out that are using these axles.
