This is a pilot valve seal kit designed to maintain hydraulic system integrity and prevent fluid leakage within the pilot control circuit. It is manufactured to strict material standards, ensuring a reliable seal that outperforms worn or damaged original seals. Operators may notice a loss of precise control, sluggish joystick response, or external hydraulic fluid leaks 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.
Initial signs of failure may include a slight sponginess or delay in hydraulic response from the pilot controls. If ignored, the leaks will worsen, leading to a noticeable loss of hydraulic pressure and potentially erratic machine movements. Continued operation with a failing seal kit can lead to increased wear on other hydraulic components.
Ensure all mating surfaces within the pilot valve housing are meticulously cleaned and free of debris before installing the new seals. Avoid using sharp tools that could nick or damage the delicate sealing surfaces during installation.
Inspect the pilot valve spool and housing for any signs of wear or scoring that could compromise the new seals' performance.
