Cummins Accessory Drive Belt Tensioner

Keep belt-driven components operating smoothly with the Cummins Accessory Drive Belt Tensioner. This unit maintains proper belt tension across pulleys, preventing slippage that can cause alternator, water pump, or A/C compressor failure. The spring-loaded arm compensates for belt wear and load changes, while the pulley surface provides stable tracking under high RPMs. With durable bushings and precision machining, it delivers steady alignment even in severe duty cycles. Installing a genuine Cummins 5581824 reduces noise, extends belt life, and protects critical accessories from unexpected breakdowns that lead to costly downtime.
