78-1366 Belt Engine to Compressor for Thermo King MD-200 w/TK 370 Engine

The 78-1366 belt engine to compressor is a serpentine drive belt that transfers power from the TK 370 engine to the compressor unit on Thermo King MD-200 refrigeration systems. This belt ensures consistent compressor rotation for reliable cooling performance.

Overview

This 78-1366 belt engine to compressor connects the TK 370 engine's crankshaft pulley to the compressor pulley on Thermo King MD-200 units. It delivers the mechanical link needed for the compressor to operate at the correct speed, keeping the refrigerated space at the set temperature. The belt is built for the specific belt engine to compressor routing on this Thermo King model.

Good To Know

Q: How often should this belt be replaced? A: Inspect it during each service interval and replace it if cracks, glazing, or fraying appear, typically every 1,000 to 2,000 operating hours.

Q: What happens if the belt slips? A: Slippage reduces compressor speed, causing inadequate cooling and potential overheating of the belt, so proper tension is critical.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
