• SOL3: CAN Communication Interfac

  Q: What are symptoms of a failing 22F-60-31600 pump solenoid on a Komatsu PC360-8?
  A: Common signs include weak hydraulic power on all functions, slow cycle times, engine stalling or bogging down under load, and active fault codes related to pump proportional valve. This 24V solenoid controls the pump's swash plate angle to regulate flow and pressure.

  Q: What does IP67 rating mean for this pump control solenoid?
  A: IP67 rating means the solenoid's electrical connectors are completely dust-tight and can withstand temporary immersion in water up to 1 meter depth. This is critical for PC360-8 excavators working in wet trenches, rainy conditions, or muddy job sites where standard solenoids would corrode and fail.

  Q: Is this a complete kit or just the solenoid coil?
  A: This is a complete solenoid kit including the coil, valve body, and necessary seals for direct installation. It is designed as a full replacement for the Komatsu 22F-60-31600 pump control solenoid assembly.
