Hey all.

I'm not really expecting an answer from this, but can't hurt to ask.

I am rebuilding the clutch type turbo 2 lsd right now.

I want to basically double the stock preload.

If you rearrange the disks in the stackup, you can double the frictional area that is used. This requires the drum that houses the spider and axle gears to become a friction surface as well.

Will this drum hold up the clutch disk riding on it, or will it cause a problem? I'm worried most about shaving metal off the drum if its not hard enough.

I checked the preload both ways tonight and by switching the disks around the preload went from 80 ft lb to 120 ft lb. This was measured completely dry, so the torque is pretty high.

I changed the stackup from

drum - plate - disk - disk - spring - spring -spring

to

drum - disk - plate - disk - spring - spring - spring

Thanks for any and all input.

 

I asked about and my diff was stacked JUST like that. Definately wasn't stock. The spring configuration anyway. I didn't have conical springs or anything you could buy out of a mazdatrix catolog.....and had 2 way cam'd ramps. Later found out it was an re-amemiya super racing... Nothing special, just cool for being one of their parts.


But yeah, on topic, i think it would be better to remove 4 springs and add 3 friction surfaces per side. So a total of 12 clutches and 2 springs. Even after i switched my config like yours and shimmed the diff, it still wasn't agressive enough for my needs and the clutches were within spec. I ended up selling my diff and changing to a welded.
