Description
Loader Parts Source, Inc. offers this Drive Belt Tensioner Assembly to replace Bobcat® OEM 6689611.
This assembly is engineered to maintain constant tension on the drive belt, reducing stress on critical components such as the alternator and water pump. By keeping the belt properly aligned and tensioned, it prevents slippage, excessive wear, and costly breakdowns.
A failing tensioner can often be identified by grinding or squealing noises, unusual belt wear, or decreased accessory performance.
