    You don't need to take the water pump off, or even the water pump pulley.... the lads are getting carried away with the scent of blood fron your skinned knuckles.

    And the TV damper (TV = Torsional Vibration), AKA crank pulley, has asymmetric holes, so it only fits on one way. It might save you some messing about if you mark it first anyway.

    Mark the crank pulley, the one on my 2e block had 4 holes in it so it could go on 1 of 4 ways [:x] :lol:

    All the engines I've done since only had the 1 hole, but I alwayds mark em just to be sure :lol:

    I find hammering a 12point socket over the bolts does the trick for me :thumbup:

    I ended up hammering a socket piece on the outside and taking it off that way with a braker bar. Not elegant.

    Got the blighter off today by hammering a socket over the top & managed to crack it with a large breaker bar :-)

    Now - How to remove the one behind it??

    Hey, my elegant method worked then:lol:.
    Is that one stuck as well? You are not having any luck, time for the socket set with the breaker bar plan.

    You mean the big bolt in the end of the crank? You don't need to remove it to do the cambelt.

    THis happened to me once before and the only way we could manage it was to remove the crank pulley with the cam belt sproket on by removing the large nut on the end of the crank shaft, then vice the sprocket and attack it with blowtorches, hammers and a piece of square section dowel hammered in, with a socket on the end (breathes). brutal and it took us an hr or so. we had already removed the starter and jammed it with, of all things, a mk 2 jag camshaft bearing (i'm sure a screw driver would suffice but the cam bearing enabled hands free locking) and tried numerous bars and the like but the allen keys kept bending!!. there probably was an easier way. We now have a gd quality hex/torx/spline 1/4 drive bit set.

    Does the pulley have to go back on a certain way then, even if the holes are symettrical as in 2e engines? I did a belt change on a 2e a week or so ago , replacing tensioner and water pump and i have a wierd bearing sort of noise, could this be why? sorry to hijack

    the only reason it has to go on a certain way is because it has a timing mark on it, putting it on wrong wouldn't casue that noise. Is the bolt working loose?

    I think you do have to get the water pump pulley off to get the lower belt cover off. The lower cover is held on by 3 or 4 nuts/bolts, at least one of which is a hex bolt (5mm IIRC). You might be able to sneak the belt in behind the lower cover without fully removing it (ie with the water pump pulley still on) but I've never tried...

    I have a large one handed spanner (camming jobby) that I use to hold the water pump pulley whilst I undo the three bolts, makes the job quite easy.

    I take it none of you are using Snap-On tools then?

    These things are TIGHT!!! I wouldn't even contemplating trying to remove one without, at the very least, a high quality allen key socket and a breaker bar.

    Draper...

    they're only as tight as they were last tightened, plus a bit for each year they have rusted up ;)

    there is a torque setting on the haynes for these bolts

    no need to remove the waterpump pulley, at least on the few that I have done :)

    It's about the 230 foot pounds if memory serves - something crazy like that anyway.

    you shouldn't need to mark the pulley as the crank timing sprocket has a small tit on it that will match up with a recess on the pulley! it'll only go on one way.

    mr ritz: Most of the engines I've worked on have been this way, but my 2.0 8v had 4 recesses in the rear of the pulley so it could go on 1 of 4 ways! Now I always set the engine to TDC before doing any work on it, so I can just refit the pulleys/fly etc using the TDC marks.

    I'm sure the last one I did had uneven spacing of the bolts so it would only go on one way... it was a while ago though.
