What size socket do I use to remove the nut in the centre of the crank pulley? It's a 66' 289.

My tool kit doesn't include this size so I need to buy one!

Thanks

Shaun

I've got 2 289's a 302 and a 351W in my shop right now and they are all 15/16. It would be intresting to find out if they used a different size. Even my BB FE is this this size. Go figure..........*G*

Both my 289 and 302 are 15/16ths as well.

Not actualy nuts, maby a little crazy........ hehe, that's why your here though, right?

I'm sure the original one is 15/16ths. That doesn't mean sombody hasn't replaced it at some point in the past with something else. I'm not sure what the thread size/pitch is, but I'll bet some other US brand crank bolts will fit but be other socket sizes. also, a bolt from the bin at an auto parts store might be the right size/pitch, but a different size head. Maby 1"?

Could the crank bolt in there have a bur or slightly mashed edges on the head that prevents the socket from seating properly? One of the bolts on one of the project cars was like that - I had to hammer on the socket to get it off and then I replaced the bolt.

IIRC i had the same problem you did and I used a 1" socket. I needed a 3" extension on it as well to clear the pulley.

Please note that all I was doing was turning the crank manually to get the distributor back in so I didn't need the best fit.

You may want to go and get a few from a store with a liberal return policy. I bought the 3/4, 15/16 and 1" at the time when I needed to do this and didn't return them. Actually, I've used all 3 on various Mustang follies since then so it was a smart move.
