Important Fitment Note: We do our best to list all compatible models. For parts that vary by production date, cab/body style, frame, engine, or option package, compare your original component and installation measurements before ordering. Cross-reference numbers are supplier-advertised and do not alone verify identical mounting, voltage, teeth or rotation. Confirm engine model, starter flange and electrical terminal layout.
Product Overview
The starter engages the refrigeration unit's engine so it can crank and start. It is an electrical starting component, not an alternator or a complete refrigeration control assembly.
A starter with a failed solenoid, worn drive or damaged motor can cause clicking or no-crank conditions. Before replacement, check battery voltage, wiring and engine engagement to avoid replacing a good starter.
Cross-reference numbers are supplier-advertised and do not alone verify identical mounting, voltage, teeth or rotation. Confirm engine model, starter flange and electrical terminal layout.
