What Does This Pilot Filter Body Do?
Houses the pilot hydraulic filter element that removes contaminants from the low-pressure pilot oil circuit. Clean pilot oil is critical for precise operation of the pilot control valves that direct the main hydraulic control valve spools in response to operator joystick inputs.
Possible Pilot Filter Body Problem Symptoms
If your machine is showing any of the following, a faulty pilot filter body may be the cause:
- Sluggish or imprecise response to boom, arm, or bucket control inputs
- Hydraulic controls feeling stiff or requiring more lever force than normal
- Pilot filter clog indicator or warning light activating on the monitor
- Erratic or jerky movement in one or more hydraulic functions
