I removed the piece of cork from the middle of my crank pulley and would like to put a bolt into it now so that I can turn the engine over. Does anyone know the size of the bolt that I put in there? I need to know exactly what to say to the parts guy because I know NOTHING about bolts. Thanks!

It is 9/16-18 right hand thread
If I were to order it from here http://www.allensfasteners.com/detail.asp?Product_ID=0032 which one should I select? I'm just using this list to figure out what to say to the guy at the parts counter (As I said, I am absolutely brain-dead when it comes to bolts).

When I eventually get a bolt into the pulley it won't strip the hole, will it? I'm going to be putting pressure on it when turning the engine over.

A bolt or threaded rod would be used to press the pulley on after it was taken off. If you wanted to take off the pulley and pulley hub, first take off the 4 bolts holding the pulley to the hub. Then you will need a puller to pull the hub off the crankshaft. Then to install the hub back onto the crankshaft, what I do is, use a piece of threaded rod, 9/16-18, maybe 5 or 6 inches long, screw it in the crankshaft . Now with a large washer and a nut press the hub on the crank.

I have just finished installing the crank pulley hub on my 368 cid 81 Cad V8. I also had to track the correct size bolt to screw into the end of the crankshaft. I actually bought two of them while I was at if. A long (3"+ 9/16" N.F. grade 8) bolt with a matching nut to press the hub onto the crank Using a 1/4" thick steel washer and seat it. The second bolt was 2" long and is used to ensure that the hub doesn't creep on the shaft. You will not be able to strip the threads in the crank just by turning the engine over using that bolt.

Cheers.....R.

alright, thanks. May I ask where you bought the bolts? I also live in Vancouver and Lordco on SW marine didn't seem to have them.

No.....they are hard to find. I got mine from an industrial supply house on Terminal Avenue, north side and just before the flea market. HD Brafasco 443 Terminal Ave. (778) 327-4397 if you want to call them.

Cheers............R.
