removal of crankshaft pulley bolt?
will a 450 Nm impact wrench remove the crankshaft pulley bolt on a 1.6 zetec SE petrol engine?
I have tried breaker bars, chain wrenches, rubber loop wrenches, long handle spanners, tapping with hammer and heat treatment, plus release oil; all with no effect at all except to bust the timing slots in the camshafts (with a timing bar). Spent endless hours on this scenario and its beginning to wear me down!!! ~ How the hell do I shift this bolt? I have also tried two very very strong men pulling in opposite directions which didn't work (except for causing one of them great personal injury!).
cheers, many many thanx!!!
PS: the pulley itself is smooth and flat with NO holes for a holding tool to insert. It's actually a double pulley with the larger one nearest to the block and a slightly smaller pulley in front of it.
