    Is there a clip or locking pin or something?

    Service Manual says to remove bolt then use steering wheel pulley, tried that and it's taking a hell of a lot of force and nothing's happening, am I missing something?

    just be careful the puller bolt is not screwing itself into the crank seen this happen before, i tapped mine off with a soft hammer came off easy and pulled the crankshaft belt pulley of with my fingers so I guess I was pretty lucky :)

    What's wrong with an angle grinder ?

    Nothing, just need to work through plan A before resorting to plan B.

    Plan A involved a hammer which should always be the first tool you reach for.

    I have a nice big hammer with a very short handle.

    My very favourite tool

    As Icram said.
    Put the bolt back on the crank but don't do all the way up.
    Head (minus washer) should be level with the front face of the harmonic balancer.
    There is a dimple in the head of the bolt for the puller tool to seat into.
    When you clamp the claws of the puller on to the pulley put to the back of the pulley.
    Common mistake people make is clamping onto the from edge.
    This is a weak area and you can brake the casiting.
    Be careful not to delaminate the outer and inner sections.

    If all else fails Get a BIGGER hammer !

    Thanks, my puller has screws that go into the threaded holes on either side of teh pulley rather than jaws, I'll put the bolt part way back in though, that's a good idea.

    Yes most harmonic balancers should have bolt holes to secure the puller to.
    Some aftermarket ones (underdrive) don't have the bolt holes or the rubber dampening ring.
    When you get the puller tightened up and start applying pressure, some times a sharp shock (hammer blow) to the tensioning bolt helps start the harmonic balancer moving.

    tassuperkart Its a lie I tell you!

    What HE said.
    However,
    If in doubt, give it a clout
    If still in doubt, get the 2 pound hammer out,
    If and then you dont succeed, a ****en bigger hammer you will need!!!!

    I'm fine for bigger hammers, as long as it's just a matter of applying more and more force until it works I'll be good. :D

    Load up the puller to buggery and then use a "technical tap" on the nose of the puller bolt thingo.
    Relying totally on the puller to overcome resistance often results in a damaged puller/pulley!
    A decent thump with a lump hammer straight smack-bang on the end of the puller bolt us often whats required to get stubborn pulleys moving.
    Dont bash its brains out, just give it a bit of a black eye.
    Tighten the puller, thump it, tighten again, thump it tighten again... and again.. and again.
    Persistence is the key rather than brute force!
    Sometimes just tighten the buggery out of the puller and leave overnight can result in success!!!
