Crankshaft Damper Pulley removal (thread direction?)

[Anonymous]

I'm having difficulty removing the damper pulley assembly to get to the timing chain and crankshaft on my '67 200ci. I know part of the problem is that I do not have the approved tool that is listed in the factory manual, but I'm trying to do the best with what I have.

I'm using a 11/16 socket, a breaker bar, and a screwdriver to hold the pulley from turning, and I just can't get the bolt to break lose. The manual says it is to be torqued to 80-100 lbs. so I figure that is partially why it is being such a bear to get lose.

Is this bolt reverse threaded or is it a normal thread (counterclockwise) to remove?

I'd hate to be fighting it only to discover that I'm turning it the opposite way.

Thanks.

8) it is standard threads. one thing you can do is set the breaker bar against the frame and bump the starter to break the bolt loose.

Last time I pulled one, I put an extension in one of the holes on the crankshaft while the motor was torn down and on an engine stand. I put the extension in the hole, against the oil pan sealing surface, turned the breaker bar on the bolt, and bam! Came right off.

Thanks for the timely responses, rbohm and 65Stang200. I'll give it a try.

Do you have a compressor and a 1/2 inch impact gun? Hit it with that and it will spin right off! Also, you can have one person on the other side, holding the flywheel bolts. Those castle bolts are pretty good holders too. =)

I take mine on and off with an electric impact 1/2" drive. Never had an issue. Good idea to use impact socket, but not neccessary.

Thanks, everyone.

I got it off, but what a task! My air impact gun must be shot. Cranked the pressure up to 140psi, tried to remove, and it just sat there.

Ended up using a breaker bar with a pipe extension added and still had to really lean into it, but it did come loose and the threads were as you all said: Standard.

Thanks again.
