Gates K081124HD Fleetrunner Micro-v Serpentine Drive Belt

Product Description

The GATES K081124HD is a FleetRunner Micro-V serpentine drive belt engineered for heavy-duty diesel fleet applications. Built with an advanced EPDM rubber compound, this belt resists deterioration from ozone exposure and water-based coolants that are common in modern diesel engine environments. The construction delivers flexibility, load capacity, and dimensional stability across extended service intervals. At 28.1 inches in length and 1.1 inches in height, the K081124HD is a direct-fit belt suited for water pump, fan, and alternator drive circuits on applicable diesel platforms. Licensed technicians and fleet maintenance professionals install this belt as a durable, long-service alternative to standard OEM replacements.

This belt is designed for use on 1995 through 2002 International/Navistar 4700 series trucks equipped with the T444 diesel engine, specifically serving the water pump, fan, and alternator drive circuit. It is positioned for fleet operators running 3/4-ton and 1-ton pickup and medium-duty truck configurations that demand a belt capable of sustained performance under high thermal load and extended operating cycles. The EPDM construction is well suited to environments where coolant exposure and elevated underhood temperatures are routine service conditions.

Key Features

• EPDM rubber construction resists ozone, heat, and water-based coolant exposure
• FleetRunner Micro-V profile for precise serpentine drive engagement
• Engineered for extreme prolonged operating temperatures common in diesel fleet applications
• Outstanding crack resistance across wide temperature ranges
• Designed for water pump, fan, and alternator drive circuits on T444 diesel platforms
• Single-unit packaging for straightforward service and inventory management

Compatibility

Compatible with 1995-2002 International/Navistar 4700 trucks equipped with the T444 diesel engine, driving the water pump, fan, and alternator accessories.

Installation Notes

Installation should be performed by a qualified diesel or fleet mechanic with the engine off and all accessory drive components de-tensioned prior to belt removal. Use a proper belt tension tool or OEM-specified tensioner release procedure to seat the Micro-V belt correctly across all pulleys. Inspect all pulleys, tensioners, and idlers for wear or misalignment before installing the new belt. Incorrect pulley alignment is the leading cause of premature belt wear on serpentine drive systems.
