Are your battery and starter cables big enough to handle the current required to crank the engine over?

Another less likely cause for the Bendix gear to hang up randomly could be a slight bend in the starter armature shaft such as might occur if the starter was accidentally dropped earlier in its existence.

The flywheel ring gear may have too much runout, or is not mounted fully home on the flywheel.

So Don, what I'm understanding now is that it isn't so tight anymore to require a 12 v battery, but sometimes locks up. The Bendix, the flywheel gear, or both may have been damaged when it WAS that tight to begin with. A single broken tooth on the flywheel could jam up the Bendix. They are not bulletproof, and the initial need for the 12 v battery may have done the dirty deed. When it happens, do you try a mallet on it, does it free up with a clunk? Do you rock it in gear to free it up? All that points to the Bendix and flywheel gear.

i think that the engine is good. I can take the starter out and futch with it a little and put back in and turns good when trying to start then it does the same thing after a few starts. I'm the engine builder so I am involved and I'm not saying there's nothing wrong motor wise but i think its outside the motor so to say. the problem is whatever spins the gear back out when l let off the starter ain't doing its job and thats what I'm trying to address, but thanks for the input. anyone else??

This is just an opinion, so consider the source... I think the problem is the engine rebuild itself. I can see the first time starting may be that tight, but it should quickly break in to the point that a good 6v battery would have no trouble kicking it over. Being so tight that the bendix locks up on you is just not right. Perhaps the main caps were switched, which would certainly cause the binding, but in any case, your rebuilder needs to be brought into the picture, as it sounds like he's the man responsible for the problem. The only other thing I can think of is that your flywheel may have been tweeked during the rebuild, causing the Bendix to lock up, but again, the rebuilder is the man to see.

I have a 32 Ford that I'm trying to keep original and I'm having a hard time doing that. first the engine is newly rebuilt and seems tight and a 6volt battery wont turn it fast enough. I have 6.3 to 6.5 volts going to starter with 6 volt battery and had to use a 12volt and firing right up and was doing good with the 12 volt starting it but now the starter seems to when it engages the flywheel, ground and stay and not come out of the starting position and when I try to hit starter again its grounded. I have had to replace the gear and that whole thing from the worm driven part to the part that the spring screws screw into. replaced all outside but spring on end. why isn't the gear coming back out and lastly, I had a friend rebuild the starter but I see ford script brushes and doesn't seem new or new stuff. I can take the starter off and bench test it and it does fine. its when I put in car and try to start it that the gear will engage the flywheel and stay there and as a result will be grounded??? So when i try to hit the starter again it wont do anything cause it grounded. i test the brass screw that the cable is on and now it will be grounded. when i take the starter cable off and test the cable its not grounded so the starter is grounding and i assume from noise and the action is grounding out. any help would be appreciated as i would like it stay as Henry built it.
