Description

The Thermo King 452117 Starter Motor Kit is a heavy-duty, factory-certified OEM replacement part engineered exclusively for transport refrigeration units running Yanmar 486V and 4.86V diesel sub-engines. Operating on a 12-Volt electrical system, this robust starter motor provides the critical high-torque output required to reliably fire up reefer engines in extreme environments, ranging from freezing winter docks to intense summer highway heat. Built to strict original equipment tolerances, it features specialized insulation and resilient internal gear structures designed to handle the relentless start-stop duty cycles of automated temperature regulation systems. Swapping out a dragging or failing starter prevents dangerous starting failures on the road, completely securing the cold chain to shield temperature-sensitive food, pharmaceutical, and chemical freight from expensive cargo spoilage.

⭐ Key Features & Benefits
  • ⚡ Genuine Thermo King OEM Component — Provides precise factory alignment, metallurgy, and performance reliability compared to low-tier generic alternatives. [1]
  • ⚡ High-Torque Cold Cranking — Optimized internal winding design ensures prompt, powerful engine turnover even when cold-soaked under severe conditions.
  • ⚡ Resilient Gear Reduction — Engineered with a durable 9-tooth drive gear configuration built to withstand heavy mechanical shock loads and engagement wear. [1, 2]
  • ⚡ Sealed Moisture & Dust Shielding — Rugged structural seals isolate sensitive internal brushes and commutators from aggressive road spray, salt, and dirt.
  • ⚡ Maximizes Fleet Uptime — Eliminates intermittent starting codes and low-voltage electrical drag to ensure consistent, autonomous reefer operation.
