Product Description

The STG50761 Starter Motor is an aftermarket replacement starter designed for compatible Onan tractor applications, including models 2140, 2145, and 2146. It features a 12-volt electrical rating, 0.6 kW power output, 9-tooth pinion, and counterclockwise (CCW) rotation. Its direct-drive design is intended for compatible small, air-cooled engine starting systems.

This starter follows a Denso-style design and cross-references Denso part numbers 228000-3270 and 228000-3271, Lester 18983, and Onan 191-2107. These reference numbers help identify a potential replacement and compare it with the starter currently installed on the equipment.

Before ordering, verify the original starter part number, voltage, rotation, pinion tooth count, mounting configuration, and electrical connections. The supplied fitment information identifies Onan 2140, 2145, and 2146 tractors, but specific production years and engine details were not provided.
