Pulling a Crank Shaft pulley

[Ceeker]

I removed and installed mine with my compressor bumped to 120psi and sat on it with the gun for about 30 sec before it started to give.

A good way of getting that sort of torque is to use your body weight. Figure out how much of a lever arm is needed for your weight. Put a foot on the breaker bar/extension at that point and put your full weight on the bar.

Thanks for all the help. I may see if my impact gun can handle it but It is only rated to 300 ft lbs so I doubt it. It will be a challenge but it will come off.

get an 8ft. cheater bar or something to remove the "jesus nut". Block one of the pistons with a block of wood thats being heald down by a peice of flat stock bolted to the block with the head bolts.

Tighten it with a good 1/2" impact gun on full strength. Trust me, it's plenty.

You should also use red loctite on the bolt when tightening if you can't reach the 350 ft-lb of torque.

I believe there is a tool that you can use.

I also heard that you can use the torque multiplication of the starter motor.


Sorta like this:

I was reading the torque specs for the crank shaft pulley. The Torque specs are something like 350 Ft Pounds. That is a crap load of Ft Pounds. My Torque wretch only goes to 150 Ft pounds.

I am trying to get some advice on pulling it? Also re-installing it. Is there any trick to this? Has anyone done an estimation of the 350 Ft pounds using a bracker bar? Also does anyone have some tips on keeping the Crank from moving?

Thanks for your help
