Hi ,

Does anyone have the workshop manuals for the procedure to recon a salisbury LSD.  Also does anyone know where I can source clutches and other misc replacement parts for these diffs.

How do I check its current condition on the bench?

Any help advice gratefully received

Minispares might be worth a try. Their 'Evolution' unit is developed from the Salisbury so there could be some parts interchangability.

There is an expoded diagram in the old Vizard book. This shows the arragement of the clutch plates and belleville washers (the cuved ones). The ones I have had have always been fairly good nick but I guess the gears and the housing inner facings could wear. You can check the torque in a vice with a torque wrench - new they are around 120lbs but get down to 30-40 when the plates are worn. Might need to make up something to connect the torque wrench - I can take a photo if you need it. Or weld a nut on an old driveshaft and hook up a H/S joint and output shaft.

You can machine the inner face of the housings and take the same off the outer rim if it is badly worn I guess. I think they use the same plates as the Escort English axle Salisbury - Burtons might have something? In fact I have wondered if the whole unit is an Escort/Cortina one with the housing machined to fit the Mini bearings. Fords use 6 bolt cw's which the Mini Salisbury has.

They are a breeze to pull apart and reassemble. The bolts are hard to get but you can use allen screws

Thanks for the reply ..... LSD's are new territory for me , have just bought a used one so no real idea what condition it is in really , will strip it soon so was interested in any procedures for doing this and also how to check it before I disassemble.

The Vizard book also has some advice about what torque setings to use for different uses. Hi torque settings for track and a lot less for hillclimbs. They are a bit too much of a handful to use on the road - the steering is too heavy. When you push the car around or drive slowly they make the most amazing clunks and clonks.

The (lower) torque setting is acheived by using more worn plates - so don't throw your old ones out. We used to use 60-80ftlbs on the track but I have run with 45 and it was OK. On a hillclimb you need to do a wavy drive up and down the access road to warm it up before each run if you are running high torque. Makes it a bit less grabby.
