    Hi,

    New to the forum today

    I need to change my crankshaft pulley/damper.

    I've done a search and found a few threads linked to it but still have a few questions:
    • Do you have to use the crankshft locking tool, for un-doing and re-torqueing the bolt; can't you simply leave the car in gear and lock the engine this way? If you do have to use it, does anyone know where to get one?
    • Is the securing bolt re-usable?
    • Does anyone know the torque figure for doing the bolt back up again?

    Hope someone can help

    Thanks

    You do need a crankshaft locking tool, leaving the car in gear will not lock the engine enough to loosen the bolt. it is tight, very tight.

    You could use a thick drill bit of similar (I did) to lock the engine up.

    Tightening torques> 100nm + 60o + 60o + 30o

    And the bolt is re-usable

    I did this job myself, although i did have access to a ramp i didn't have the locking tool, you need to remove all the under engine covers, helps to remove the crank pulley from underneath, then what i did was found the bung high up in the gearbox that gives you access to the flywheel i made my own tool from a screwdriver to lock the flywheel, then i got a mate to hold the tool why i undid the crank bolt, this bolt is VERY VERY tight. People moan about how tight it is I didn't believe them until i had a go and it takes a load of effort to undo, refit is same as removal, but you MUST use a new bolt. HTH

    Thanks Cal

    Thanks for the reply, great stuff
    Few more questions now...
    • does the crank have a keyway to locate the pulley?
    • Where do you lock the engine and do you do it at top dead centre or something?

    Thanks again

    Yes the repacment crankpulley has a locating groove, don't know about the engine, but i did turn mine until it locked into what i thought was a locating hole, just did that by moving the crank and having someone else checking the flywheel

    Technical data says the bolt is re-usable.

    Number 2 is where the crankshaft hole is located, just under the starter motor.

    Engine needs to be at tdc which can be done by removing the rocker cover and making sure the cam lobes are facing (pic 1). There are a few holes on the back of the flywheel and not all can be used for locking the engine up, so make sure the engine is set at TDC.

    Little trick I do is to pull a glowplug out (number 1 or 4) put my finger over the hole and crank the engine clockwise untill the compression stops. The hole for the locking pin should be then more or less in line.

    Thats great, pic really helps

    As I don't have the proper pin, could anyone shed any light on what diameter of material (or drill bit ) I should be looking for to supplement for the pin?

    BTW, I've ordered a new bolt just to be sure.

    The pin looks like this

    Sorry can't remember the actual dimensions, but the very front (smaller bit of the pin) goes into the flywheel. The thicker part fits the engine side of the bell housing.

    You need a brill bit or similar the same size of the small part of the pin so you can slot it into the flywheel.

    IIRC it was something around 1/2 inch.

    If I get the time and if I remember I will check for you tomorrow but you definately need a new bolt. I think the torque setting is somewhere around 300Nm
