Dayco Accessory Drive Belt Idler Pulley 89104

Accessory Drive Belt Idler Pulley. (89104) by Dayco

This Dayco ® No Slack ® Heavy Duty Idler/Tensioner Pulley is designed to replace idler and tensioner pulleys for serpentine drives in heavy duty diesel engine applications. This pulley is manufactured from high strength engineered polymer material to afford wear resistance under harsh environments; and, it features double pressed-in bearings to provide long bearing life despite the shock loads experienced in diesel engine applications. The performance demands of original equipment manufacturers of over-the-road trucking and off-road equipment require a "built for punishment" heavy duty construction, that is why they specify Dayco ® No Slack ® Heavy Duty pulleys.
