CDL woes

[ToaDisco]

I cant seem to get my CDL to engage. I can easily shift between lo-hi/CDL lo-high, But cdl is not engaging. I am sure it is not engaging due to the detroit not locking up.

I was having problems with it popping out while wheeling a few days ago, and then it wouldnt engage at all. :angry

This is on a 94 discovery with a 2in body lift.

P.S This started happening pretty much after the bodylift was put on, though it could have nothing to do with the problem :confused

Let me have any tips/suggestions as MAR is soon approaching and it would suck to not have CDL :eek:

Thanks

Did you Check the linkage?

[ToaDisco]

The linkage moves, there doesnt appear to be anything visibly wrong. Am going to drench in pb blaster to loosen everything up, even though I can shift easily between hi/lo ect..

Follow-up Post:

Pb blasted everything, linkage/TC shifter shifts effortlessly. Linkage seems to be ok.(looks like it always has)

Is there a fuse/solenoid that activates the CDL?

[Davis]

There is no fuse that activates it, but there is an indicator light/sensor that is plugged in on top of the linkage--I would at least test that out and make sure it is not just your light---can you tell by driving whether or not it is engaged?

Hmmm, when you did the body lift did you extend the levers for the tranns and t-case? when you put the T-case in diff lock there is a spring that engages the diff, sometimes it need a little help you normally only have to drive a few inches to get it to engage. Since this started happening with the body lift I would think that it is interfering with the linkage it movement of the t-case lever. There is a small cover on the side of the t-case that can be removed so you can see the spring that engages the diff lock.

I have never seen a D-90 with a body lift? Do you have a picture?

o okay I assumed it was a Defender since its the D-90.com. MY B

[ToaDisco]

I did put a t-case extension on the tc lever, so I am not sure whether or not that is the problem. And I did wheel some fight after the body lift and got cdl(but it did pop out once)

I usually did have to put it in drive to get the cdl to fully lock up, so maybe my spring isnt fully engaging.

Time to go look at that

[Mike Hippert]

I would bet your linkage is not moving the little stud sticking up out of the t-case enough, I would have someone move the lever in and out of lock while you watch it from the underside, then pull off the linkage and move it by hand with a wrench to see if you are fully moving things with the lever. This may be hard in the disco, I have watched it in the 90 but it is tight to get your head up there to see whats going on.

Well, I was messing around with the tc shifter loosening everything up with the pb blaster/trying one last attmept to get cld to engage, then something let go and I have no resistance what so ever in the tc shifter. :( Something in the linkage let go,so no cdl or hi/lo

I can see where the linkage is slipping to the cdl(there is a splined area that connects the vertical rod to the cdl nut/lever, and there is another linkage that is now hanging loose, which i am guessing is the hi/lo selector.

Never really paid much attention to working of the cdl/tc linkage before(since it has always worked) So I dont really have any idea how it works :eek:


Could anyone post a pic of a fully operational cdl/tc linkage(assuming it is relatively the same for a d-90/disco), it would be much appreciated :)
