Ashcroft ATB LSD for LT230.

Have just installed a Quaife unit in the TC run into the same problem as Fubar
with .040" end float had to machine a .134" shim to give some preload must be
a design tolerance I had bought the Quaife prior to the Ashcroft being
available:mad: be interesting to see how it compares;)

There is a technical paper on how the Torsen style diffs work linked from the wikipedia article. I think the bias ratio is different on the Ashcroft and Quaife diffs but still interesting background on the design.

That's the original T1 style centre, the Torsen T2, Quaife, Tru-Trac and ATB centres use an entirely different, simplified and stronger parallel axis worm gear design. (I made the same mistake years ago)

I'll dig up a thread I posted the differences on ages ago.

[edit] Here it is, with photos and drawings and the Ashcrofts chiming in too http://www.aulro.com/afvb/technical-...ferential.html

I've been thinking about Ashcroft ATB's for a while now, & got this off the Ashcroft web site, Bob [click on limited slip differentials, ] this is about 12 months old.

I could use one . . . or two. I expect there would be a market for them considering how many LT95s are still around.

I'd be in for one as well............ all quiet from Ashcroft though.

Haven't been following this subject, but are you saying you fit the standard atb into an lt230, or its a special one made for the lt230? I have one set up for my front diff, which could go in the lt230 and I'll order a locker for the front:) if this is the case

It's a special for the LT230.

Aha thanks dougal, I thought so. Will leave front diff where it is. Might look into the t/case one before I bolt the rest of the bits to it. Is it a case out job, or can it be done in car? Can't remember with the 230.
