LSD plate pack
Does anyone have a cutaway or a diagram of the Sierra LSD diff plates? I've opened one for checking and can't remember the order of the
first and last plates.

The standard sierra LSD diff doesn't have plates. It's a viscous coupling type.

What he said  , and you really mustn't take them apart either.

Too late guys. Pandora's box - it's apart. The viscous pack is just a stack of interleaved plates with the magic sticky grease between
them. It's not as horrendous as the folklore has you believe. Similar to some autobox innards.
I just need to know what the plate order is.
I'll do a write up if it survives.

It doesn't matter what order the plates "were" in, because you may as well throw it away. The viscous fluid is pumped in under
pressure, you will see two holes that are plugged, one is the inlet the other the vent. Once dismantled it will not work, well at least not as
intended. There are a couple of places that will refill them, but to be honest it's cheaper to get a new one, as the old one is probabley worn
anyway. Not what you want to hear, I am sure, but thats how it is. Regards Ray

Thanks for the good news Ray. There certainly wasn't any 'fluid' inside. Just a particularly sticky grease similar consistencey to
Pritt stick so am i correct in thinking it's supposed to be more fluid?
Who are the refillers of diffs? Otherwise I'm looking at the thick end of £600 for a Quaife or £150 for another potentially clapped out sierra
LSD. I recon a refurb could be a cost effective option.

The "fluid" is just like very thick grease, sort of grey"ish" in colour. I do know that it is possable to get them
refilled, but don't have any information on where or who, so can't help there I am afraid. May be worth contacting Will at PPC Mag, sure
he will know. Regards Ray
