FAQ 1: How do I know if the hydraulic pump needs replacing?

You may need a new hydraulic pump if you notice a significant decrease in power, slow operation of the excavator arm, or excessive noise coming from the pump. You can also check for fluid leaks or abnormal heat from the pump itself.

FAQ 2: What is the difference between a pilot valve and a main control valve?

A pilot valve (or servo valve) uses a small amount of hydraulic pressure to control a larger flow of hydraulic fluid, often directing it to the main control valve. The main control valve then regulates the flow to the hydraulic cylinders or motors, controlling the machine's movements.
