My '52 gmc COE with a 302 GMC had a 12v conversion done to it sometime before I got it. I've been having problems with the starter and pulled it today. The drive gear on the starter looks like it was taking a major beating, some off the teeth were wore off to hooks, some were broke and flattened off. The starter has 9 teeth and a tag number of 1107626. That number comes back to a 55-56 Bel-Air with a 235.
Next I counted the teeth on the ring gear. It has 132 teeth and a casting number of 2135483. Now in my parts book a 2135482 comes back as a 270 GMC flywheel, there is no listing in my books for a 2135483 like my flywheel has. Assuming I didn't misread the casting, does anybody have a listing for the 2135483 part number?
More importantly does anybody know if these two will run together? As it is now the ring gear looks ok, but I don't want to replace the starter drive gear just to have it chew itself or the ring gear up. The way the drive gear looks, I'd say the two don't exactly match each other, but I don't know that for sure.
Can I take the new drive gear and run it by hand in the ring gear to see if the two mesh before the drive gear is put on the starter?
Thanks,
Scott
