Removing the crank pulley on a zetec.
With the engine out!!!
I thought the air impact gun I have would make short work of the crank pulley bolt on the engine stand but unfortunately not.
I am going to have to use a breaker bar - but how do I stop the engine turning. The engine is on a stand and it would be tricky taking it off at the
moment. If I take the sump off, is there an easy way to stop the crank turning without damaging anything??

Three ways, two require a beautiful assistant. If the flywheel is still on get your beautiful assistant put a bar across a couple of the dowels while
you undo the bolt with a breaker bar. If the flywheel is off do the same across a couple of flywheel bolts. If the sump is off an suitable block of
wood between a crank web and the engine block works a treat.

Try a decent impact wrench, some of the cheaper ones are only good for spinning nuts off after they have been loosened
PS Try putting some air tool oil down the inlet of the air wrench while holding the trigger before attempting to loosen tight fittings, it works a
bit like doing a wet compression test and gives the wrench a bit more power

i put two flywheel bolts in and got someone to hold a breaker bar between them and i had another breaker on the other the crank pulley bolt it worked
fine
i done mine while it was swinging on my engine crane was quite a laugh trying to do it
Less weight more speed, more power more speed
If in doubt, give it a clout

If the flywheel is on bend a piece of 4mm x 25mm bar into a rough u shape so the top bits of the U each mesh with the ring gear. Then put a longish
bolt through one of the holes that hold the engine to the gearbox. the bit of bar then hits the bolt when you turn the crank and locks it allowing you
to put some force on the breaker bar on the crank.
I got mine off easily enough like this.

I know its late now but if you wedge a socket on the bolt and breaker bar bellow chassis checking rotation of engine and just flick the ignition, job
done.

Does that work with the engine out and on a stand?

+1 thats what I did but made a notch in a piece of steel that sat in the flywheel teeth.
