This is an adjust cylinder seal kit designed to restore the functionality of the hydraulic system in Volvo excavators. It ensures proper sealing to prevent fluid loss and maintain consistent cylinder operation, meeting stringent quality standards for durability. Failure typically manifests as slow or jerky boom/arm movements, external hydraulic fluid leaks around the cylinder rod, or a loss of holding pressure.
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 sign of seal failure is often a visible hydraulic fluid leak around the cylinder rod. If ignored, the leak will worsen, leading to a gradual loss of cylinder performance and potential system contamination. Continued operation with degraded seals can result in uneven equipment movement and increased wear on other hydraulic components.
Ensure all internal cylinder surfaces are meticulously cleaned to prevent debris from damaging the new seals during installation. Do not use sharp tools or excessive force when seating the seals, as this can cause premature failure.
Inspect the cylinder rod for any signs of scoring or wear that could compromise the new seals' effectiveness.
