This is a hydraulic cylinder seal kit designed to replace worn seals in the second boom cylinder of Volvo excavators. It ensures proper sealing to maintain hydraulic pressure and prevent fluid leakage, which is critical for smooth boom operation. A failed seal kit will typically manifest as slow or jerky boom movement, external hydraulic fluid leaks around the cylinder rod, and a loss of lifting capacity.
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 a failing boom cylinder seal kit is often visible hydraulic fluid leakage from the cylinder rod. If ignored, this leakage will increase, leading to a gradual loss of hydraulic pressure and slower, less responsive boom movements. Eventually, the cylinder may fail to hold its position under load, significantly impacting the excavator's operational capability.
Ensure the cylinder bore is meticulously clean before installing new seals to prevent premature wear. Avoid using sharp tools that could nick or damage the new seals during insertion.
Inspect the cylinder rod for any scoring or damage that could compromise the new seals' effectiveness.
