This is a pilot valve seal kit designed to restore the proper function of the pilot hydraulic control system in Volvo equipment. It utilizes high-quality elastomers and seals that meet or exceed original equipment specifications, ensuring durability and preventing leaks that would occur with worn or damaged seals. Failure of these seals can lead to sluggish or unresponsive pilot controls, making precise machine operation difficult and potentially causing operator fatigue.
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 pilot valve seal failure include a slight delay in control response or a feeling of 'softness' in the joystick operation. If left unaddressed, the controls will become increasingly sluggish and may drift, leading to reduced operational efficiency and potential damage to surrounding components due to imprecise movements.
Ensure the pilot valve body and all internal spools are thoroughly cleaned before installing new seals to prevent contamination. Avoid using sharp tools when removing old seals or installing new ones, as this can easily damage the valve bore or the new seals.
Inspect the pilot valve spools for scoring or wear, and check the hydraulic fluid for contamination when replacing pilot valve seals.
