Distributor for Super A

james Ashcraft · May 9, 2009

I may have made a major mistake. I was putting new points in the distributor and the screw head that holds part of the points in was really wore out after 40+ years. I decided to replace with a new screw but I didn't have the exact length. I did have one just a little longer and I think that was a mistake. When I tried to start the engine - no fire - wouldn't start. I removed the distributor cap and turned the engine over with the crank - rotor didn't turn. My next question is the distributor gear held in place with a pin or did the gear break off the shaft. I have owned the tractor for more that 40 years - I have I&T manual but it doesn't say - I can't tell from the exploded view. I'll remove it in the morning when I have more time. Just wondering what to expect. Thanks for any help.

James: Your correct, that screw can't be any longer. Probably you stripped distributor drive gears that were well worn anyhow. New from CaseIH they are about $200. Quite often you can buy used sets for $50., but make sure you get a match set that have worked together.

The gear's held on with a solid pin. The screw probably jammed the advance weights before shearing the pin or breaking the gear so you may have a little more work under that plate.

If it makes you feel better you are not the first one that has done that and you will not be the last. I knew better from 30/40 years back but forgot couple years ago and trashed drive gears, was lucky at that as often distribitur shaft is bent.

NDS: I guess I was one of the lucky ones. The time I tried the longer screw, I had the distributor out on the bench, tried rotating it by hand. My thoughts were at the time, if it used a bit longer screw it would make the change easier.

Update on distributor - removed from tractor today - the shear pin was broke but both gears were good. Removed point plate and the long screw had did a little damage to the cover over the automatic advance. Got all that fixed and put a pin in the shaft and gear - reinstalled shaft with bottom gear and discovered shaft is bent. Now have to find another distributor.
