This is a pilot valve seal kit designed to restore the proper sealing function within the pilot hydraulic control system of Volvo excavators. It contains all necessary seals and O-rings manufactured to precise dimensions and material specifications for reliable operation. Operators may experience a loss of control precision, slow or jerky pilot control response, or hydraulic fluid leaks around the pilot valve when these seals 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.
The first indication of failing pilot valve seals is often a slight sponginess or delay in the response of hydraulic controls. If left unaddressed, this can progress to noticeable jerky movements or a complete loss of precise control over hydraulic functions. Continued operation with compromised seals can lead to internal pilot valve wear and potential contamination of the main hydraulic system.
Thoroughly clean the pilot valve housing and all internal spools before installing new seals to prevent damage from debris. Ensure all new seals are properly lubricated with clean hydraulic fluid before insertion to prevent tearing.
Inspect the pilot hydraulic fluid and filter for any signs of contamination or degradation when replacing pilot valve seals.
