This is an adjust cylinder seal kit, designed to replace worn seals within the adjust cylinder of Volvo excavators, maintaining proper hydraulic pressure and preventing leaks. It is manufactured from durable, high-grade materials that resist wear and chemical degradation, outperforming degraded seals that cause stiffness or leakage. Operators may experience slow or jerky boom/arm movements, or a loss of holding pressure 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.
A failing adjust cylinder seal kit may first present as a slight drift in the boom or arm when not actively engaged. If left unaddressed, the cylinder will lose its ability to hold position effectively, leading to unpredictable equipment behavior and potential safety hazards. Continued operation with leaking seals can also lead to contamination of the hydraulic system.
Ensure all internal cylinder surfaces are meticulously cleaned and free of any burrs or scratches before installing the new seals. Avoid using sharp tools that could nick or damage the delicate sealing surfaces during installation.
Inspect the cylinder rod and bore for scoring or wear, and check the hydraulic fluid for contamination when replacing the adjust cylinder seal kit.
