Product Details
Part Number: 781871
The Thermo King Belt 781871 is supplied as a heavy-duty drive belt for transport refrigeration applications. This component uses industry-standard elastomer compounds and a reinforced tensile cord to resist heat, oil, and mechanical fatigue encountered in reefer trailer and truck installations. Exact dimensional fitment varies by Thermo King unit model; verify the belt part number against unit serials with certified technicians for precise application guidance.
Efficiency & Sustainability
The Thermo King Belt 781871 supports efficient accessory drive operation that contributes to steady temperature control and optimized compressor loading. Proper belt condition reduces drivetrain losses and supports fuel-efficient cooling strategies across refrigerated fleets. When integrated into modern control ecosystems, such as Smart Reefer SR-4 telematics-equipped systems, well-maintained drive components help fleets manage routes and energy use more effectively.
Installation & Maintenance Tips
Install using OEM-recommended tensioning practices and compatible clamps or tensioners. Inspect belts during scheduled service intervals for wear, glazing, or fraying and replace at the first sign of progressive deterioration. Use certified Thermo King service procedures to confirm correct routing and pulley alignment for reliable belt life.
Real-World Applications
Use the Thermo King Belt 781871 on refrigerated trailers, truck-mounted reefers, and transport refrigeration units where Thermo King drive belts are specified for alternator, blower, or accessory drives. This component suits fleet operations that prioritize uptime, consistent temperature control, and predictable maintenance intervals. Available for installation and service in Amarillo, Lubbock, Odessa, and throughout West Texas.
Backed by Thermo King’s engineering and supported by certified technicians at West Texas Thermo King, this component delivers lasting performance and uptime assurance for fleet operations.
