Which rotor does GE 8B52 timer use?

[Chris]

I have an 8B52 clock / timer from the '30's in for repair and something is wrong. The rotor is working, but the clock is very slow. Does it take the typical B rotor at 1 rpm? Thanks!

Anyone have an answer?

I suspect the GE/Telechron 8B52 Radio Timer uses the H or S 3.6 RPM (60 Hz) rotor. I think this is a post-WWII production.

Show a photo of the motor/rotor and assembly when asking for assistance.

It uses the short tail BF style rotor with 36 tooth, 9/16" O.D. pinion gear. (1 RPM)

BF rotor's are pretty low torque so both the rotor and clock movement need to be in good condition.
