I have had my 1942 H for 13 years and for the most part it has run like a top... but yesterday for some reason it got stuck on top dead center and I can not hand crank it over. In the past, I could just crank on past TDC by hand. It was running fine last week. Spun bearing perhaps? Hope not, but I am not sure.

Were you trying to start it at the time? If so, the starter could just be wedged in the flywheel ring gear. Just loosen the two starter bolts and pull it back a bit and reinstall it. Common occurrence when the starter bendix or flywheel ring gear get worn.

fifth is the only gear to rock it in. it might do it, but looetening the starter will.
A new style clutch drive starter drive will make it all better if it is the issue.
Almost no engine will stick on TDC due to the forces on the crank being near zero at the rod angle of near zero. Jim

Ok....so it was stuck, not sure where at in the stroke. Many times, it would stop somewhere near the top of the stroke and the battery would not turn it over. I would crank it on past the sticking point by hand, and continue on with the battery starting it. But not this time. I was just looking for some ideas about what might have happened and I found the answer here. Thank you guys

Small battery cables are also a suspect.
They should be 0gauge or 00gauge welding grade cables with soldered on terminals. Less than this on a H or M will slow the starter dramatically. Jim

When the starter locks the engine the problem is worn teeth on the drive and possibly also the ring gear. Usually replacing the starter drive is enough to correct the problem. If there are teeth burred over on the ring gear you can make it serviceable but filing off the rough areas. Just make sure the surface that the drive pushes against is smooth.
