Clutch LSD rear?

[spdracrm3]

There were two posts on e30tech (a sadly lost resourse) of two rebuilds of the tcase viscous coupling. Fluid and seals are available ,just cut apart on lathe clean and straighten plates and add correct quantity/viscosity fluid and reweld.

I've rebuilt the center VC myself, it's definitely possible. I actually used a brake disc lath to cut mine apart. It's still working great to this day (3 years later). Unfortunately, my thread was on e30-tech..

Another user on this forum (I'll have to look up his thread) machined a collar for his center VC to accept a sealed cover which allows him to refill it without welding it back together. It's really neat.

He also took the VC out of the rear diff to discover that it had a lid with a snap ring that held it down, much like he had done with the center.

I have one cut open awaiting fluid and another donor to rebuild(two spare Tcases with blown VC's). Have the seals from Mcmaster-carr and own a tig welder

You better start a thread w pics! I'll be happy to answer any questions if you have any. I mig'd mine so you'll probably have a way cleaner result with a tig. I had to turn my welds back down on the lathe afterwords..

They are welded shut by robots in a vacuum.

Curious to hear more about this...

Not in a vacuum.. Probably a submerged arc weld. It can and has been done.

yeah I was under the impression that a rebuild was not feasible, hence my original question
