    Clutch Change

    The clutch in my Disco has started to slip in 5th at peak torque -I suspected it was going when I bought it.
    I'm going to pull out the transmission and change the clutch in the next week or two. I've done plenty of clutches but never a Disco. Does anyone have any tips or gotchas that I need to watch out for? Would appreciate any input.

    getting it out is easy, put a scraficial matress under the vehicle un bolt and remove the gear you need to to drop the box unbolt the bell housing and with a long rope hoik it quick (if your not trying to save any part of the clutch you wont hurt anything). but before you do this make sure the engine is adequately supported....

    its very agricultural but works a treat..... a more refined method without resorting to buying a trans jack with the right mount plate on it is

    Pull 3 of the studs out of the mounting plate for the bell housing.

    Install 3 lengths of threaded rod about 3 foot long (i used the outside top 2 and one of the bottoms)

    coat liberally in grease and use these to slide the gear box on using a trolly jack just back from the gbox drain with a longish bar tied off of the bottom of the handbrake drum and a bolt on the pto housing for rotation and tilt control.

    Providing you got the clutch lined up right you can get it in and bolted in about a minute with 2 people.

    to pull the rods double nut them at the back and unwind or use ye olde vice grips/small pipe wrench.

    you got a hoist and a strong transmission jack.....?




    or are you doing it at home on the floor......?


    its big and its heavy.....you will need 2 or 3 trolley jacks to lower and then raise the box(with transfer case) ......
    and probably the same number of people to control the jacks.....

    i made a plate that fits under the gearbox and t/c with some bits welded on to stop the box from twisting or sliding off also put a chain around the gearbox to stop it falling off i then welded the plate to my trolly jack

    in the rangie i had to drive the car on ramps at the rear and use chassis stands at the front it is needed so the bell housing can clear the underside of the car thats if you are moving the box right out of the way

    Thanks for the advice. I had intended to use a trolley jack and possibly build the jig illustrated in the manuals on the RAVE CD. While it is alot of work to build, for what may be a one-off job, it may be worth the trouble. There's nothing worse that being pinned under a car with a heavy transmission lying across you chest!
    The rods through the bell housing holes is an interesting idea. I may look into that - anything that helps line up the gearbox with the engine is good!

    Be prepared to replace the clutch fork and thrust bearing.

    The forks used now, are relatively thin pressed steel and the ball wears through the pivot seat. It is a good idea to weld some backing steel on the other side of the seat, before you put it in.

    I'm not saying this is anything to do with your current problems, but that it is likely to be worn and you will not like having to pull the box out again soon to replace the clutch fork.
