Cummins Dual Fueler Belt System Twin CP3 Fuel Pump

                   Cummins Diesel Truck Can Be Equipped With Two Fuel Injection Pumps 


The drive belt system may use 1 belt or 2 belts. The drive belt is thin so that it can bend backwards and has several ribs to match the grooves in the pulleys. The drive belts are made of different types of rubbers, chloroprene or EPDM, and have different layers or plays containing either fiber cloth or cords for reinforcement.

Both sides of the drive belt may be used to drive the different accessory drive components. When the back side of the drive belt is used to drive a pulley, the pulley is smooth.

The drive belt is pulled by the crankshaft balance pulley across the accessory drive component pulleys. The spring loaded drive belt tension-er keeps constant tension on the drive belt to prevent the drive belt from slipping. The drive belt tension-er arm will move when loads are applied to the drive belt by the accessory drive components and the crankshaft.

The drive belt system may have an idler pulley, which is used to add wrap to the adjacent pulleys. Some systems use an idler pulley in place of an accessory drive component when the vehicle is not equipped with the accessory.

 Some of the accessories are driven by two fuel injection pumps called CP3 designed by Bosch
