1391010A-JN Leece Neville Starter Motor

One New Aftermarket Replacement Leece-Neville (Prestolite) S152 Series Starter Motor

This heavy-duty 24V starter motor is part of the Prestolite / Leece-Neville S152 series, designed for demanding industrial, marine, military, and off-highway diesel engine applications. The S152 features a co-axial solenoid design with a dual-stage operating solenoid mounted around the armature shaft, an oil-sealed wet-clutch drive end, and a pre-engagement system that engages the pinion with reduced power before full cranking power is applied -- protecting both the ring gear and pinion from damage. The -JN suffix designates an aftermarket distributor variant of OEM part number 1391010A.
