I sure picked the wrong time of the year to start this one, but after much patience and research, I finally laid down two black stripes!!
I have a stock R200 with CV axles and I bought a (slightly used) KAAZ 1.5-way CLSD off ebay that was previously installed in an S13 / 240SX.
I found that the unit doesn't have provisions for the internal snap-ring, so I had to settle for "floating".
Another minor detail was that one of the 280ZX CV stub axles (splined portion) was about 1/4" too long and would bottom out inside the LSD unit.
I just used a chop-saw to cut the hardened steel. It got pretty hot since it is a friction blade. Then I chamfered it, but I didn't do much quenching...at least I don't think it annealed too much (cooling too slowly).
Here is a spare that I practiced on:
I took it out for a spin across town and it felt pretty good. It kind of had the knocking / clunking / chatter in sharp, slow turns at the beginning. I suppose the tube CLSD fluid wasn't fully mixed into the gear oil yet...
I even made my own pneumatic pump to fill the gear oil into the diff housing! (piece of cake)
Sorry I haven't posted pics of the LSD carrier itself.
I did get the side lash set and new bearings pressed on, so that added ~$75 to the cost of the project, but at least I'm sure that the contact patch between the pinion and ring gear is right on!
Now to see if I can get a grip at the track next week!
Bye-bye stock open carrier (whoo hoo!!!)
