The PSS110 is a 110V single-phase replacement motor for PIERCE PS654-E series worm gear winches — 1.5 HP, 1,800 RPM, NEMA 56C mounting frame. Capacitor-start design with ball bearings, sized for shop and dock duty. Drop-in replacement when the original motor wears out or fails.
When should I replace the motor on a 110V worm gear winch?
Two telltale signs. The motor starts but doesn't pull rated capacity — usually a weak capacitor or worn winding. Or the motor doesn't start at all under load and trips on overcurrent — usually an open winding. Either case, this PSS110 is the OEM-spec replacement.
