Pulley And Belt Kit For Bert Pump 40 Tooth

The Pulley and Belt Kit for Bert Pump 40 Tooth (Barnes MPN 8937-HTD) is engineered for high-performance hydraulic and cooling system installations where reliable power transmission is non-negotiable. Whether you're building a custom hot rod, upgrading a vintage muscle car, or assembling a competition engine bay, this HTD pulley system ensures consistent belt engagement and minimal slip under demanding load conditions. Mechanics and fabricators rely on this kit to maintain efficient coolant circulation, supercharger operation, or auxiliary pump function without the hassle of custom-fabricated solutions.

The 40-tooth HTD (High Torque Drive) design delivers superior grip compared to serpentine or V-belt systems, reducing slippage during peak torque events and maintaining consistent RPM synchronization between the pump and crankshaft. HTD belts feature precisely machined teeth that interlock with matching pulley grooves, eliminating belt creep and ensuring repeatable timing—critical when driving mechanical fuel pumps, water pumps, or superchargers where accuracy matters. The Barnes engineering pedigree guarantees dimensional precision and material durability, meaning this kit integrates seamlessly into existing Bert pump assemblies without shimming or modification. Weighing just 0.86 pounds, the compact 7.55 x 2.2 x 10.8-inch package fits tight engine compartments without sacrificing structural integrity.

This pulley and belt kit excels in street performance, drag racing, and off-road applications where continuous pump operation and vibration resistance prevent downtime. Installation is straightforward for anyone with basic mechanical skill—simply align the HTD teeth, secure the pulley, and route the belt with proper tension. Compatibility is assured with Bert pump models designed for 40-tooth drive pulleys; cross-reference your pump documentation or consult a Bert distributor to confirm your specific mount configuration. For builders prioritizing reliability, repeatability, and professional-grade components, this Barnes kit eliminates guesswork and delivers proven performance mile after mile.
