Description

Overview

Engine To Compressor Belt Thermo King SLXe SLXi suits the main engine-driven belt path on selected Thermo King SLXe and SLXi trailer refrigeration units. It keeps drive transfer steady across the matched pulley layout, so the belt system can hold speed and tension under normal operating load. Because these units share family naming across several variants, buyers should match the installed belt profile and routing before ordering.

Features

• Suits SLXe-100, SLXe-200, SLXe-300, SLXe-400 and SLXe Spectrum applications
• Also covers SLXi-100, SLXi-200, SLXi-300 Whisper Pro and SLXi-400 layouts
• Uses a 10PK Poly-V belt profile for this drive family
• Fits engine-side drive systems where the removed belt matches the installed routing

Compliance and Safety

Isolate the unit before service, then inspect pulley wear and alignment at the same time. If the old belt shows glazing, rib damage or uneven tracking, correct the cause first because a new belt will not mask a worn belt path.

Trailer Applications

Engine To Compressor Belt Thermo King SLXe SLXi is used in trailer refrigeration service on engine-driven SLXe and SLXi layouts where the belt path matches the removed part. It covers common fleet units in the 100, 200, 300, 400 and Spectrum groups, so it suits workshop repairs where the engine-side belt needs a like-for-like replacement.
