Can't remove pulley nut off 1.6 Tipo

Wedge long bar on ground and use the starter to rotate the engine. The weight of the car working against the rotation of the engine will crack it.

Windy Gun is just about the best way. The continuous nudging of the gun eventualy breaks the friction/tightness.

You could try your own short, sharp not to heavy taps on the end of a

3/4inch drive bar. Not one, two or three but 30 to 100. Brute force IS NOT the way to crack this nut.

Failing that you will have to make up a flywheel lock for the starter ring teeth.

I had to remove the pulley nut on a 1.6 Tipe DGT several yeras ago and they are on tight.

I think the only way to remove these is to lock the flywheel through the starter access using a screwdriver - get somebody to hold it.

Then, get a large ring spanner of the correct size, secure it to the bolt and hit the other end with a 2 pound hammer - use short sharp and controlled strikes - do not thump madly at it. It is important that all the play is taken out through the engine, put tension on the spanner to remove all backlash so that when the hammer is struct against the spanner it feels solid.

Other ideas, such as putting the car in 1st gear, applying the brakes and using the cars weight just make it more likely that the spanner will slip off and run the risk of rounding the bolt.

Alternatively, an air impact wrench would whip it off in a few seconds.

Any joy with your nuts hellraiser ?

Not had time to fiddle with them yet, too busy working :) Will have a crack at it next weekend, this one is a bit fully booked by the other half!

************************************************* Just a thought here. Could it be a left-hand threading?

I have had success in removing stubborn threaded hardware by using a GIANT air driven impact driver. I have one that is certified to the limit of 550 foot-pounds of torque. I have never had to use this on an automotive part. I have used it for engine and clutch pulleys on motorcycles. J. R. Graham Texas, U.S.A.

In most cases Fiat mark left-hand threaded nuts with a notch in the points between the nut flats. For the Tipo in question I'm 100% sure it is a righ-hand thread (well it was on mine :-)
