The teeth on the flywheel gear look like new. On another SC, I removed the starter and looked at the flywheel gear. This SC has 12V battery with alternator. The front of the teeth on the flywheel gear are badly worn down. It appears that about 1/4 of the width of the teeth has been chewed off. Is this condition due to using a 12V alternator/battery on a 6V starter? [Reply]   [No Email]

However, the 6v starter on 12v is kind of asking for the situation to be worse. Now, if my headlights were just changed to 12v, I'd be in even better shape, but I feel the starter situation is cured with the 12v field coil in it. I was woried I might have the ring worn too bad in a few spots to cause a problem anyway, but for the last year or so it has worked fine. [Reply]  [No Email]

Or, it could just be that the Super C with the good gears has had them replaced at some point in its life... 6V or 12V has little or nothing to do with starter gear wear on a 60 year old tractor. Most 12V conversions were done long after the tractor stopped being the main power on the farm. By then the tractor had been started thousands of times. The number of 12V starts is a mere fraction of the number of 6V starts. [Reply]  [No Email]

Weak batts and poor cables also bad bBendix all help to gring teeth of flywheel then 12v comes along and sort of finishes it. [Reply]  [No Email]

Yes it most likely is due to the 12V. system, IF you did not change the field windings in the starter to 12v. when it was changed over. I have a 240U (same C-123 engine) that did the same thing. Starter drive would not engage the flywheel starter ring every time, would grind 2-3-4 times and finally engege almost every time I started it. Starter finally quit and when I took it to my local auto-electric guy, I told him how it had acted for years before it quit. He said the starter is spinning too fast before it engages so he installed 12v. windings in it when he repaired it and now it not only engages every time, but it starts quicker. Cost about $75 on top of the regular repair, so about $175 total, but it sure works great now. [Reply]  [No Email]
