The power steering pump works in parallel with the car engine thanks to the drive belt that connects the two units. To transmit torque with minimal loss, a power steering pulley is installed on the pump. The part is a strong round roller with one or more ribs in the seat for the belt.

The operation of a power steering pump pulley

The pulley material is high-strength alloy or carbon steel. The SWAG brand Pulley, power steering pump is mounted on a hub that connects the roller to the pump shaft and transmits torque to the rotor of the unit with minimal losses. Through the power steering belt, the pulley causes the power steering pump to rotate. Through the bearing, the pulley is attached to the pump shaft. Regardless of whether the pulley is running on a serpentine belt or a V-type belt, the pulley is usually sized to provide higher engine speed during power steering pump operation. Remember to keep the pulley clean and free of oil or play in the bearing. Breakdowns that occur due to damage to the power steering pulley:

1. Difficulty turning the steering wheel
2. The appearance of noise in the power steering hydraulic system;
3. The power steering belt starts to squeak.
