This is a seal kit designed to replace worn seals within the boom cylinder of Volvo excavators, ensuring proper hydraulic pressure retention and smooth operation of the boom assembly. It is manufactured to meet stringent Volvo quality standards, providing superior durability and sealing performance compared to degraded or damaged original seals. Operators may notice slow or jerky boom movements, or visible hydraulic fluid leaks around the cylinder rod when this seal kit fails.

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 failure include a slight lag in boom extension or retraction speed. If ignored, the boom may exhibit noticeable drift when holding a position, and hydraulic fluid loss will become apparent. Continued operation with failed seals can lead to reduced hydraulic system efficiency and potential damage to other hydraulic components.
Ensure the cylinder bore and rod are meticulously cleaned before installation to prevent debris from damaging the new seals. Avoid using sharp tools to install the seals, as this can easily cause nicks or tears.
Inspect the hydraulic fluid for contamination and check the condition of the cylinder rod for any scoring or wear that might affect the new seals.
