What is a Cam Rocker in a Hydraulic Pump?
The cam rocker plays a central role in the piston reciprocation process. It transforms the rotating motion of the drive shaft into the forward/backward movement of pistons within the hydraulic cylinder block. A worn cam rocker can cause vibration, irregular oil output, and pump failure. YNF’s YNF16490 is designed to meet OEM specs, with cam precision that ensures perfect piston stroke timing in mini excavator pump systems.
