I ordered this timer motor to convert my existing 208-240 VAC Intermatic electromechanical timer to run on 110-125 VAC. It was an exact match. There are only 2 small torx screws that attach the motor to the timer mechanism. When changing the engine, I sprayed all the gears with Teflon spray grease. The new motor runs very well on the timer and appears to be keeping up with the times after a week of use.
