This pilot valve seal kit is essential for maintaining the precise operation of the pilot hydraulic system, preventing leaks and ensuring smooth control. It is manufactured using high-performance elastomers that resist wear and hydraulic fluid degradation, offering superior longevity compared to aged or damaged seals. Operators might notice a loss of sensitivity in joystick controls, jerky movements, or a general decrease in hydraulic system responsiveness when these seals begin to fail.
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.
Initial symptoms of failing pilot valve seals include a slight sponginess or delay in hydraulic control response. If ignored, leaks will increase, leading to a significant loss of pilot pressure, making the machine sluggish and difficult to control precisely. This can result in inefficient operation and increased operator fatigue.
Carefully clean the pilot valve spool and bore before installing the new seals to prevent contamination. Ensure each seal is oriented correctly according to the valve's design to guarantee proper sealing.
Inspect the pilot valve spool and bore for any signs of wear or damage when replacing the seals in this kit.
