519-8020: 9PK Serpentine Belt

Descriptions: The Serpentine Belt is also called an accessory Belt, fan Belt, and Drive Belt. It allows the Belt to pass over more than three pulleys with a large enough wrap angle to avoid slipping, idler pulleys that press against the back of the belt are included, forcing the belt into a serpentine shape. The belt is long and snakes through several pulleys. Attributes: • Can withstand wear and tear resistance. • Provide 9 ribs for a better grip and reduce slippage. • Effective Length of the Belt will be 1540 ± 6mm. • Flexible materials such as rubber or synthetic polymers, which allow them to bend and wrap. • Orion Rib Compound is used that is Carbon Blacked Rubber helps to good balance of abrasion resistance. Applications: The Serpentine Belt is used in Accessory Drives connected with various components like Alternators and Fan Drives with Idler Pullies. Mostly used in Cat 311D, 312D, 313D, 314D, and 315 Excavators.
