This V-belt transmits power from the engine crankshaft pulley to the accessory drive components, such as the alternator, water pump, and fan. It sits in the front drive system of the host machine, maintaining tension across the pulleys to prevent slip under load. A worn or glazed belt produces a squealing noise at startup or under heavy load and can cause the cooling fan to under-speed, leading to elevated coolant temperatures. The belt is manufactured by Gates to match the original cross-section and pitch length, preserving the correct pulley wrap angle and tension range. On installation, inspect the pulleys for wear and adjust the tensioner to the manufacturer’s specification.
