|Telechron Repair Tip #32 - Pinion
One of the most common faults one finds in Telechron and GE clocks is a broken set pinion. That's the little gear at the end of the set shaft. They're built too thin (they really should be made of bronze) and they crack all the time. When they're cracked, turning the set knob won't do anything. In the worst case, it falls off and the set shaft falls right out of the clock.
On the right, I'm actually trying to replace the shaft, not the pinion. You can see (bottom shaft) some numbskull clipped the end (and the knob) off the set shaft because they didn't know it was reverse-threaded. I'm going to save that pinion and stick it on the later, 1950's style shaft above.
In the next pic, you can see the shaft stuck very loosely in the jaws of a vice. You're pretty much just going to let it hang by the pinion. Then you can tap the shaft out of the pinion with a finish nail or a punch.
Gently tap the old pinion on the new shaft (happily, all the post-1933 shafts and pinions seem to be interchangeable). You may have to grind down any extra material sticking past the pinion--it depends on the clock. When in doubt, though, remove any extra; if it's too long, a rap to the set shaft could actually dent the dial of your reassembled clock !
