Lsd in a open diff transfer box.

Iím having some trouble with transfer boxes.. I need to know if the gear set off an open diff transfer box is the same as the lsd gear set..
I have 2 lsd transfer boxes with destroyed pinions and the only thing I can find says they are different heights.
I canít find much information on this and any input would be appreciated..

They might be, depending on the version.

There are two or three different sizes of diff carrier so if you have the same version, the crownwheel will fit.

The pinion height will be related to the diameter of the crownwheel.

Clive_w will be able to provide more information.

Cheers,

Simon

No problem, I'm sure he'll be along at some point.

Is it a helical or plated LSD?

If it's a TME diff (helical diff bolts have a non countersunk head) then you'll need the larger size crownwheel. If the bolts are countersunk, it's a non-TME so the crownwheel is smaller. IIRC there are two diameters of diff pack but not sure if that translates to the crownwheel or not.

Probably the best thing to do is buy another box and if it's a non lsd one swap the diff pack over, although most of the 5/6 boxes seem to be lsd ones.

Yes, they do translate. The diff O/D, bell I/D and O/D and CW I/D are all bigger on the TME. The CWP is identical to E6 apart from itís I/D.

Clive, the bit you quoted was referring to the non TME diffs of which I've seen a few different sizes. Do you know if there are different sized non TME crownwheels (4/5/6)?

Thanks for the very,very,very late reply Clive..

but we eventually got to the bottom of it..
The LSD from the 5 will fit in the 4 gear set but the LSD from the TME only fits the gear set from the 6.. Forgive me if im wrong but mine is now set with Backlash at 6 tho, and it's silent..

Good to be driving it again after a few months of head scratching and trying to get info on what went wrong in the first place..
