how to hand turn 230/250

ive got a 1952 chevrolet truck with a 230 or a 250, its not the original motor.

im trying to turn the motor over by hand but the crank pulley has no bolt to get a wrench on it.

how do i go about turning th motor over by hand.

also, i belive the motor is stuck, this is why im trying to do it by hand.

 

A rubber belt strap wrench?? Don't know if you have one around, but, I'd throw mine on the crank pulley and give it a try.

 

Use the flywheel.

 

Prybar on the flywheel teeth, or a flywheel turning tool if there's room.

 

2 bolts in the harmonic balancer where the pully mounts, and a bar between them.


Pull the spark plugs out, you should be able to turn it by hand

 

be patient with trying to free the motor. i have unstuck a few, by squirting loosener fluids [insert your favorite here] and gently prying on the flywheel- every day, once in the morning once before i went home. once it breaks free work it back and forth gently till it makes a full revolution. #6 cylinder is usually the culprit due to the fact condensation runs down the intake toward the back.

 

If it's a standard trans put it in high gear and rock the truck.

 

i was thinking about what "sunbeam" said, but im thinking about hooking my other truck to it and tugging it. its only become frozen within the past 3 years.

 

That works, take the plugs out to make sure you don't "hydraulic" the motor!

 

pull the head off and see whats going on inside the cylinders.

 

This way you will get the most leverage
