Motorcraft JK4577A V-Belt

Motorcraft belts are tested for long life and quality operation.|Durability test specification - 10-years/150,000 miles; simulated in real-world conditions.|Contamination Resistance test determines the belt's sensitivity to Engine oil, power steering fluid and Engine coolant.|The Four-Pulley Hot Test is conducted to test the belt's durability under high temperature, high load and adverse environmental conditions.|The Hot and Cold Test measures the belt's durability under high temperature, high load; and cold temperature, no load conditions.|Three-Pulley Rib Crack Test checks the belt's durability with regard to rib cracking and chunking at high temperature and high belt speed.|Dynamic O-zone Testing is conducted to determine the belt's ability to resist O-zone - a significant factor in rubber compound degradation.|The Noise Test assesses the noise characteristics of a V-ribbed belt under various degrees of misalignment and environmental conditions.|The Stationary Oven Test determines the influence of high temperatures on the physical properties of the vulcanized rubber belts.|Friction testing is completed to ensure that proper friction characteristics exist and there is no slipping under load.|In addition to bench tests, Motorcraft belts are tested in the application for which they will be used. Why Buy: The only parts recommended by Ford Motor Company for Ford, Lincoln, and Mercury vehicles. Motorcraft belts are designed for minimum maintenance and maximum performance. Manufactured of premium-quality materials to strict Ford Engineering standards. Polyester cords help belt resist stretching, minimize slipping and provide excellent performance in applications with short adjustment drive systems. Multi-layer laminated construction and die-cut edge design provides quiet operation and long life. Motorcraft cogged belts are designed to flex easily around even the smallest pulley. The molded cog design helps preserve belt strength, eliminate rough edges and provides quiet operation. Precise fit and belt lengths results in fast installations and can provide fewer customer complaints.
