Turning Engine By Hand with No Centerbolt - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hello,
I have a 283 that I just did a compression test on and found two cylinders (3 and 7) to be low. Actually all of the cylinders on the driver side are lower then the passenger, but them two are the worse.
I wanted to do a leak down test on both of these to see if I can tell whats up with them, but I dont have a centerbolt holding the front damper and pulley onto the crankshaft to turn it by hand.

Is there some method to turn the engine by hand other then just grabbing the fan and doing it?

Thank You !
