wp20564 - Genuine International Starter Motor - 1 - wisentpartscenter.com

Description

Genuine International MITIN3179 Starter Motor is a Mitsubishi Electric heavy-duty 12-volt starter used to crank the engine by turning the flywheel during startup. This unit uses a gear-reduction design with 5.5 kW output, giving the starter the torque needed to turn large-displacement diesel engines without requiring an oversized motor.

Verify fitment with us before ordering to ensure the correct part for your application.

Purpose of the Part

The MITIN3179 uses battery power to turn the engine fast enough for combustion to begin. When the key or start command is activated, the starter pinion engages the flywheel ring gear, cranks the engine, and then disengages once the engine starts.

Issue Symptoms / When to Replace

A failing starter may crank the engine slowly, work only intermittently, produce a click without turning the engine, or stop cranking completely. Grinding during startup can point to pinion or ring-gear engagement problems. Weak batteries, corroded cables, poor grounds, or excessive voltage drop can create many of the same symptoms, so the starting circuit should be checked before replacing the starter.
