The SprayTech 755-201 Drive Shaft and Pinion assembly is a mechanical power transmission component that transfers rotational force from the motor to the pump mechanism on compatible sprayer models.
This assembly converts the motor's rotary motion into the linear reciprocating motion required for pump operation. The drive shaft connects to the motor output, while the pinion gear engages with other drive components to create the pumping action. Proper alignment and condition of these components are essential for efficient power transfer and smooth pump operation.
