This is a boom cylinder seal kit designed to maintain hydraulic pressure and prevent contamination within the boom cylinder assembly of Volvo excavators. It is manufactured to meet stringent OEM standards, ensuring superior sealing performance compared to worn or damaged seals that lead to leaks and reduced system efficiency. Operators may notice slow or jerky boom movements, external hydraulic fluid leaks around the cylinder, or a loss of lifting power 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.
Initial signs of failure include a slight external hydraulic fluid leak around the boom cylinder rod. If ignored, the leak will worsen, leading to a noticeable loss of hydraulic pressure and slower, less responsive boom operation. Continued neglect can result in significant hydraulic fluid loss and compromised lifting capacity, potentially halting operations.
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 delicate sealing surfaces during insertion.
Inspect the cylinder rod for any signs of scoring or damage, and check the hydraulic fluid level and condition.
