At 3 o'clock you can see scratches where the rotor rubbed the stator.

I used dremel and diamond burr to removed a little metal from stator.

Used my Dewalt lathe, 1/2 inch drill. A energy cloth to polish scratches off rotor. Between sanding and grinding I got lucky. Rotor an stator don't touch

I've got bowling machine before my son was born, over 42 years ago
The lift motor has always been noisy. . I always thought I was a gear noise. Come to find out the motor.

Now I need to stop by a place in town and see if I can get a gizmo to splice the flat belt.

I'm a winner, my grinding sanding fix did the trick

No way to remove the gear on shaft.

Grandkids will be happy.
 
Never heard of a lacing tool.
Don't know farmers who use antique flat belts either.
Planning on stopping off at a place in town that many years ago sold flat belts to farmers and factories.
 
Alligator belt lacing doesn't need a special tool. I got it from my local hardware store for the flat belts back when I was running my sawmill.

I don't understand why you couldn't remove the gear and replace the bronze "ball" bushing in the bearing holder?

I've repaired many little shaded pole motors like that by matching up and using a bushing from my "collection" of new and used shaded pole motors.

Kitchen and bath fans are one source. Surplus places used to sell an assortment of the little motors cheap, probably can't find them there anymore, tho!

Almost always it's the bushing at the "fan" or "drive" end that fails, I save the little motors as the bushing at the opposite end is almost always still "good" and can be swapped to the "worn" end of another motor.

Would be a better solution than grinding away at the stator, I would assume as you increase the "gap" between the stator and rotor the motor will tend to run "hotter".
 
Nothing wrong with bushing or shaft.
If you have ever taken a bathroom fan apart you would see how bushing is held in place.

I used screw driver, bent the tin that centers the bushing.
 
It's always easy to second guess what I
had to do without being there.
1. I couldn't get gear off.

2. I've never seen a shaded pole motor
with two different shaft sizes.

So replacing the motor wasn't an option

3. Both ends of the motor had to be OEM
TO match up with the gearboxs mounting
bolts.

I had no options
Newer lift motor wouldn't work.
This is 1957 Bally.
My jukebox is also a 1956 Bally.
 
Found belt lacing at Coldwell in Terre Haute
They make big belts for conveyors in factories.
I asked how much.
They said it's free because I'm in there a lot.

Coldwell is my go to place for bearings, hydraulic hoses, belts.
 
Coldwell Bearings is a store in the center of town. I love living in Terre Haute because of all my go to places that take good care of me.
And it's close by. Or it's Amazon for hard to find parts.
 
If you don't find any alligator lacing let me know I have lots. I have clipper lacing too, but you'd need the tool.
 
Thanks. I got some at Coldwell Bearings in Terre Haute.
Should have it fixed tomorrow morning before it gets hot.
Grandkids will be Happy next time they visit grandpa.
