    Okay. At least over the next two weeks I'll have plenty of spare time to get on with it.

    Thanks for passing on the info, which is a great help.

    The Haynes manual is a waste of time; a big let down.

    I want to use 'her' for starting doing green lanes. Maybe then I'll move on to doing the vergins by the side of the road! The old ones are the best...

    Cheers

    Get yourself a RAVE CD it's service manuals and such on a CD I've never used the haynes manual but the RAVE CD is ok although I don't think it will be much good on a stuck diff lock lever.

    Hi Buddy,

    Sorted out my Disco's seized selector problem.

    All the advice was a great help.

    Just like with yours, mine had seized up at the end in the ally bush. The biggest problem was undoing the bolts holding the unit ontop of the g/box. I took your advice and after fixing it, loaded it all up with a good anti corrosion grease.

    Seems like a pretty crappy design. If I need to do it again, I think I'll fit a grease nipple so I can use a flexible grease gun and put it on my future list of maintenance jobs to do.

    I thought six hours was a bit much, but now I know different. The first time six hours is probably about right - though if I ever have to do it again, it should be quicker.

    Many thanks again for ALL the good helpful advice.

    Now my Landy has got its nuts back!

    glad you got it worked out second time is always faster but let's hope you won't need to do it again at least not on that Rover.

    I think the design is OK, its the lack of any notes in the handbook suggesting that the diff lock be engaged on a fairly regular basis to ensure it won't seize.......

    Default Diff Lock stuck

    I got a 1995 Disco and the Diff lock will work as follows:
    I put it in Neutral and move the diff lock lever to the left and it goes over
    fine. The diif lock dash light appears as it should.
    I cannot shift it any more than that though.
    The question I have is, is this sufficient to make a difference in the
    performance of my disco, and is it worth it to get the console off and work on the greasing of it. Or even still going to the dealership
    (I know, I know the dealer sucks the money like a ***** sucks cock)
    But is it worth taking these steps? thanks.

    I'm not sure what you mean by it will not go any farther once the light comes on your diff lock is engaged. Or do you mean it won't shift out of Neutral? There are two different functions in the Lever
    1. Shift from High to Neutral to Low range.
    2. Engage and Disengage the Diff Lock.

    You should be able to engage and disengage the diff lock in any position high, low and neutral. There are no shift gates for the diff lock. If it does not allow you to move it back and forth between diff locked and unlocked then I would wager something in the linkage is buggered up and it's not seized.

    My personal opinion is stay away from the Dealer. Not only do they charge you a fortune but they mostly try and make you fix things you don't need/want fixed. Find yourself an independent mechanic who is well versed in Rovers if you don't like doing your own work but the best bet for a Rover owner is to do their own work.

    Default Dif lock stuck

    My only other question here is (on a 95 disco)
    how much "elbow grease" can I use to try and shift my dif.
    before I risk snapping/breaking something in there.

    My thinking is that it is simply sticking and I can loosen it manually
    without opening things up. I recall it being stuck but eventually shifting a couple years ago.
    And I'm hoping that still can work?

    Or should I avoid doing the above idea due to the probability that the grease that keeps things moving in there,
    is dried, or non - existent? Bringing an inevitable need to open up and grease.

    thanks!

    Here's the Discovery I transfercase illustration.

    As you can see, the diff lock mechanism is comprised of a lot of little parts that require lubrication and operation to keep in top condition. Unfortunately, to do the job properly, you will need to open 'er up and get after it...

    Hope this helps, all the parts are listed below in case you happen to break something or might possibly need replacement.

    Note: I've edited my original post in this thread on page 1 with the above information. Also, made it a sticky for reference.
