This is a pilot valve seal kit, containing all necessary seals and O-rings to rebuild a pilot control valve and restore its proper function. It is manufactured to precise dimensions and material specifications, ensuring a leak-free seal and smooth operation compared to worn or damaged seals. Operators may notice jerky or imprecise joystick movements, or a loss of pilot pressure when this seal kit fails.
Always verify with serial number before ordering.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first indication of a failing pilot valve seal kit is often a slight drift or creep in the hydraulic functions controlled by the pilot. If ignored, this can progress to more significant issues like sluggish response, loss of holding pressure, or complete loss of pilot control. This can lead to inefficient operation and potential safety concerns due to unpredictable machine movement.
Carefully inspect the valve spool and bore for any nicks or scratches that could damage the new seals during installation. Ensure all seals are properly seated and lubricated before reassembling the valve.
Inspect the pilot hydraulic filter and clean the pilot valve spool and housing thoroughly when replacing the pilot valve seals.
