Can't removing the crankshaft pully bolt

[Pete W]

Hi,

I want to change the timing set on my 1961 Comet and can't remove the pulley bolt. It is stuck on there good. The pulley is a two groove type to run an AC compressor and has no hole to put a screw driver in. In gear, the car just wants to roll when I try to get it off. Any idea's?

Thanks,

Pete

Um ... I don't know if this applies here, but sometimes such things have left hand threads. Don't try anything else until somebody here jumps in to confirm or correct this. You might be making it worse.

Right hand thread, but use shock to loosen it. Get a helper to hold the socket onto the bolt head, while the breaker bar hangs down below. The helper also applies a light "pretension" anticlockwise to the breaker.

With a 3 pound hammer, the guy laying under the front bumper whacks the breaker bar sharply and repeatedly. The suddenness of impact is what does it. After less than ten hits, it will start to yield.

Cheers, Adam.

Alternately, an air or electric impact wrench works wonders.

Air tools are just wonderful!

Pete, get a 13/16 socket & place it on a breaker bar.
Place socket on crankshaft damper bolt.
Place breaker bar with socket on bolt & rotate engine so the breaker bar is in contact with the sub-frame on the right side.
Have someone hold the breaker bar on the lower side of the frame.
Make sure the battery is at full charge.
Disconnect the coil wire from the distributor. Or pull the plug on your duraspark.
Crank the engine over with the starter & the bolt should break loose.
Good luck, Bill

It's important to disconnect the coil wire when doing this sort of work!

The other week, I "bumped" my DD to move it forward about 3'. It started, and took off in low gear with the handbrake on and my arm stuck in the barely-open window. (Was heading for a neighbour's fence, too...)

I have seen a tool in a factory ford manual to make a crankshaft locking tool that goes in place of the starter.... a rattle gun is better, though.

I'm with Bill. Just did this the other day and it worked like a champ. COIL WIRE FIRST.

I cant even imagine the damage if the thing started!

So, didja stop it

If worse comes to worse, you can take the oil pan off and jam a block of wood against one of the crankshaft counterweights so the crank will stay put. Thats what I did but I had planned on changing the oil pan gasket anyway.

Have someone pushing on the brakes when you try to remove it??

 

[Pete W]

I used a breaker bar and gave it a few whacks with a five lb hammer and off it came!

Thanks for your help

And I thought I was the only one that had ever done that!
