Can some one send me a pic of the top of a DII LT230 without the little nut to engage diff lock?

I have an idea

Couldn't get even my little camera in that space, will have to find a makeup mirror to try again next week when Im off again. As far as I can tell there is a slight ridge in the casting, roughly a circular, about where the CDL should be. there are no plates or screws, it just plain isn't there. I don't know what the internal differences are. I can't begin to imagine how one would retrofit a CDL without replacing the whole darn thing. On the brighter side, ETC works like a charm so far. my main concern is heat buildup in the brakes and ABS pump after extended crawling. I am also unsure as to whether my rover has the CDL sensing circuit...

So there is no plate with 3 bolts?

I have an LT230 in pieces on my back porch and got to thinking how it could be achieved on one without the CDL nut. My though is that worst case it would be a matter of changing out the front output housing for one with the provision, but I was hoping it would be a matter of replacing a blanking plate with the correct parts which looks to be somewhat easy and dare I say

Ron,
I will try again next week to get an actual visual.... but the project needs quite a bit of research (It has been on my back burner for a while). I was hoping to score exploded diagrams of both to compare. who knows what differences lie inside the case. as I stated earlier, I haven't been able to establish whether there is a CDL sensing circuit. I had resigned myself just to replace the whole darn LT230 in a few years... Iv'e got one that is particularly loud. Unless someone makes a true track like device for the center diff (yeah right)...

I have the exploded diagram of the LT230 with the diff lock. I have not been able to locate a diagram of one without it.

Actually, a Tru trac like device already is made for the center dif. it is called a quaife and is available from GBR. Not quite a CDL and I think a retrofit is your best option but still its out there.

:)

Never know until you ask!

Ron: Go to www.roversdownsouth.com and look under transmissions. far left is a t'box from a 4.0 missing any kind of "nut"

Can someone look at this and confirm this does not have the nut?

If this one does not have the nut I am willing to bet that it would be cake to install the few parts necessary.

Ron, from what I can see, on the upper half of the TC in that picture, it does look like the TC is missing the CDL nut. It just looks blank where the CDL nut should be.

But it's very hard to tell from that picture.

Actually it looks like the CDL nut is there. Compare these two photos. The first one I took of a 4.0 disco 2 tranny at a junk yard. The second is from the RDS site.

Does anyone know the approx. production date of D2's WITHOUT the CDL "NUT"? I am about to have the TC swapped out if neccessary. Thank you in advance.

Ok,

Now I am just shooting from the hip here but the cover plate with 3 bolts can be replaced with the attached stuff beneath it (not sure if any other dismanting is involved but I can check)

If the principal difference between the ones with the nut and the ones without the nut is this assembly, the upgrade should be really easy and quite inexpensive.

But I would need to see one without the nut to confirm this was the issue. Thus far one has not fallen in my hands. If someone could post a pic that definately does not have it that would be very cool.

Ron

PS I don't have a DII, I just had this idea and I want to see if it will work.

I have a 2002 DII that was manufactured August 2001. It does NOT have the nut assembly.

Ok,

That SUCKS. No really easy solution BUT it looks like you can still replace the whole output housing.

Basically you would need to find a front output housing from an LT230 (this should not be hard, and although I am not 100% sure any LT230 should suffice, provided you are willing to swap over your output flange so maybe a DII one whould be ideal).

You would have to pull the front drive shaft.

Then you could take the six bolts holding the high low selector housing off, then the seven bolts holding the front output housing on. (Not sure if this could be accomplished with the box in situ or not, if you are interested take a look)

Swap output housings (looks like there is nothing else to do), silconing the flange, and you have your nut and diff lock.

No need to swap the whole case. All the differential locking stuff is located in the front output housing.

Ron

LT230 in pieces as we speak :)

PS the one roversdownsouth has does have the nut.

The other two things I forgot which would serious complicate the procedure is that you would have to take the T-case off the frame mount and that you should check the bearing preload in the case.

All the stuff I have read indicates the stuff is all in the case, just no actuating mechanism. See if you can Lawrance in Melbourne (oz) on LR Enthusiast site forums. He has been thru all this - put a bowden cable operated lever on the arm; turn off car, engage CDL, start car, it recognizes CDL in, turns off traction control. Reverse sequence when done with slippery work.

Actually there are two different DII T-cases. One has everything but the linkage, the other one does not have the machining on the front output housing to accept the internal linkage, detent and switch. My procedure is based on the latter. The former is easy as you just need linkage.

Hi Ron,

Ok direct from landrover :- Up to and including some 2001 build cdl is there it is just not connected. From 2001 on cdl parts are missing, all the same inside just the cdl TAKEN OUT FOR SPARES!!!
Please do not ask how I got this info as a smack in the mouth often offends LoL.

Dan,

That can't be right. The case is not even machined to accept the CDL parts.

I still say swap the front output housings and go with it (I supposed you could half-ass the preload by using the bearing race and shim out of the original case)

So it can be done and it would probably be about as much as an ARB or detroit.

What about a quaiffe? Is that spelled right?
 

Ron
Posted on Friday, March 08, 2002 - 08:57 pm:   Edit Post Delete Post Print Post

Quaiffe, yes

A quaiffe is similar in design to a trutrac as it is a gear driven limited slip. They make them for both the axle differentials and according to Bill @ GBR they also have them for the center differential.

But to install one you have to really disassemble the T-case. Not too bad but you would have to drop it and remove and replace one bearing.
