Help Crankshaft toothed timing pulley bolt removal

Has anybody removed the crankshaft toothed timing pulley bolt from a 1.6 twinspark. The Alfa Info disk has the bolt as left hand thread and 280ft lbs torque.

I have had a 500ft lbs impact gun on it (no flywheel locking tool) and it doesnt want to budge.

Does the flywheel locking tool make that much of a difference?

Re: Crankshaft toothed timing pulley bolt removal

Yup! Knock up a tool!

Make up a tool that locates on the four bolt holes surrounding the crank bolt. When undoing, rest the tool handle on a block of wood and undo the L/H crank bolt.

Folks say that they just use an air gun to undo these bolts but how do they do them back up to the correct torque without a holding tool?
mmm...among them the local Main Dealer!!!

i've done this only with the engine out though, i used a rubber mallet to trap the crank (sump off and pistons out) a 2ft break bar and my 16st fat **** to shift it i did go...
But doing it up i put loads of thread lock on and gunned it up with an air impact wrench right or wrongly this is the way i've done it... there is no way i could of done it upto that recommended torque with the engine on an enginestand using a torque wrench...
