December 30, 200618 yr comment_194233 I recently had this done on one of my cars. As I watched the mechanic do so, AFTER he had gotten the crank to move at all, he would rotate one way until it stopped, then he'd rotate the other again until it stopped. Each time he'd push just a small bit. It took him a couple of hours of doing this one tiny bit at a time before he was able to get a full rotation out of it. Then again, this engine had only sat for a couple of years. And it was running well, when I shut it off the last time.E Link to comment https://www.classiczcars.com/forums/topic/22661-trouble-with-hand-cranking/?&page=2#findComment-194233 Share on other sites More sharing options...
December 30, 200618 yr Author comment_194240 Thanks for the good words. I thought I may have messed up something or was going at it the wrong way. I will use some patience. Now that the bolt is loose, do I need to tighten it and then keep trying to turn it by over tightening? Should the belts be off?

December 30, 200618 yr comment_194246 Just one more thing to think about . As if you need to hear this . Each time these engines are shut down . There are two cylinders open to the out side air and moisture. This is because there is a intake and a exhost valve open. In addition the valve stems ALL are exposed in the ports if open. If they are rusted they may stick either closed or open . Also the rust could destroy the valve seals. Be vary sure that the valves are lubed all along the valve train by pouring oil over them. If you have the manifoulds off shoot WD 40 over everything . Just pay attention that the valves are moving up and down when the engine is rotating , BEFORE spinning on the starter . Other wise you could damage the pistons ,head , or valves . That is if one or more stick open when the piston rotates up. Right Mike !
