Heat may be an issue.
I used to try and get myself killed in a '76 MG B GT V8, and had similar issues. When hot, the started would barely crank, if at all. Even after a rebuild things didn't improve much. A heatshield and partial exhaust manifold wrap somewhat solved the issue.

Do those trucks have a voltage regulator?

http://i47.photobucket.com/albums/f191/bluejames19/IMG_20140818_173312_233_zpslshgulae.jpg This is my bitchin '49 Chevy 1/2 ton. To be succinct, it don't too good. Still running on original 6v system, starter was rebuilt properly and converted to high torque, cables were made custom out of heavy guage wire, starter and battery have been properly grounded, battery is an Optima and starts my '54 2 ton flatbed no problem. -It will only start when battery has been on the charger and is at 100% -If I turn it off after driving for some time and immediately try to restart it, no joy. Starter makes maybe 1 revolution and quits -I tried a 12v battery jumper on the advice of my mechanic, no dice -Mechanic who was working on it reccomends 12v conversion WTF is it possessed? Should I get a Catholic priest? Points? Coil? Help! Do not jump it with 12V ever again. |

So I've gotten it to start reliably by using the 12v battery jumper. Starter makes one revolution but that is enough apparently to start. I pulled the flywheel dust cover off and saw there was some chipping on the flywheel front of teeth (pics). Not sure how long that has been like that. Could be from years ago or just this week with the new high speed starter. I'm going to pull the starter and switch it out with the one on my 54 GMC, we'll see what happens then.

Get another starter. I had a special wound hi torque starter that wouldn't start at all. I re-installed my old starter and it worked fine.
Also, plan on converting to 12V. I have done it several times. I can't see your photos from work, but if your stuck is stock, I could rewire it in about an hour. It isn't hard. I recently had a starter problem with a V8 equipped 48 Ford. I thought the Optima was dying and had been on the shelf for a couple years while I built the truck. I found out after a tow truck ride that the starter was slowly shorting and on the final trip was a dead short. A key indicator of this is the starter housing will be very hot, very quick. The new starter is now click, boom...instant start. Also, dump the floor starter. Use a solenoid and then any type of ignition switch will work. Again, convert it to 12V ASAP. |

Nothing to add but I hope you get it figured out and that's a great looking old truck.

So is the floor starter switch part of the starter or a stand alone part? I assume stand alone.
Is that an old part? How are the connections? Replacing that with a solenoid wouldn't be a bad idea.

Well I fixed it. Looks like when they rebuilt the starter they added a bushing to the shaft and that stopped the pinion gear from engaging the flywheel fully. Not sure what the thinking was on that. Tiny little bushing caused a big headache. Thanks to all who helped!

Glad you got it fixed.
On this ones first trip, a 14 year old yellow top Optima failed:   I think I got my money's worth on that battery. |
