Applicable Models: XCMG XE60GPro Hydraulic Excavator

Tensioner assembly is the core component of engine accessory drive system. It presses drive belt by elastic tension to maintain proper belt tightness, transmit power, reduce belt slipping and beating noise, and ensure normal operation of alternator, fan and other accessories. Fatigued tension spring, worn bearing and cracked pulley will cause belt beating, abnormal noise, belt jumping‑tooth and breakage, resulting in engine accessory failure and shutdown.
