Super M Crank pulley

Ok , started tearing down my wintwer project, a 1953 super M. Just wondering how the crank pulley comes off. Looks like a HUGE nut is bart of the pulley? About 2 and 3/4 inch socket? Looks like i see screw threads under the nut? How does THAT come off? Regular thread, or reverse? I'm thinking I should get that off before i pull the engine, so i can put it in gear and lock up the motor. I'll be pulling the front bolster to get at it. Any advice, input or ideas guys? Anyone?... Thanks Darryl
 
Darryl - That big crank pulley nut is regular, right-hand threaded with a 2-1/2" hex. I found 2-1/2" stamped steel wheel bearing socket worked nicely.

On my '53 SM the nut came loose with little effort - a couple good tugs on a breaker bar against engine compression had the nut turning.

Once the nut is off the pulley simply slides off the crank. Mine came off easily by hand - no puller required.
 
On the other end of the spectrum, LOL, my pulley took my dad and I each working a die bar with a 4 foot cheater pipe to pry my pulley off my SMD. I was really afraid we were going to break something. Some people have to use a puller.

Had to laugh at how different those relies were. Iif it were mine I've found that lots of heat and lots of PB Blaste works, plus patience. Do the heat/PB for a few days, it helps t get iin there and loosen up things.
 
Great tip about the wheel bearing socket. I doubt if I will be so lucky to have the pulley just slide of though. Heres hoping!!
 
I agree! Most of the time you have to use the PB Blaster and the big torch, several times, over a few days to bust some of this old stuff loose. I've seen where other guys also use a bearing seperator behind it to pull it off. Might have to buy some new tools. Part of the fun , right?
