This is a pilot valve seal kit for Volvo excavators, containing the necessary seals to repair a leaking or malfunctioning pilot hydraulic control valve. It ensures precise control of hydraulic functions by maintaining proper pressure and preventing fluid bypass within the valve spool. Symptoms of worn pilot valve seals include jerky or imprecise joystick/pedal response, loss of hydraulic pressure, or unintended equipment movement.
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 initial symptom is often a slight hesitation or jerkiness in the hydraulic controls, such as the joystick or pedals. If ignored, this can worsen to a noticeable loss of control precision, difficulty maintaining a steady hydraulic flow, and potential unintended equipment movements.
Meticulously clean the pilot valve body and spool before installing new seals to prevent contamination. Ensure all seals are properly lubricated with clean hydraulic fluid to prevent damage during installation.
While the pilot valve is disassembled, inspect the valve spool for any scoring or wear that might necessitate replacement.
