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 rod, 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 leak of hydraulic fluid around the boom cylinder rod. If left unaddressed, the leaks will worsen, leading to a gradual loss of lifting capacity and slower boom actuation. Continued operation with failing seals can result in increased hydraulic system contamination and potential damage to the cylinder rod.
Ensure the cylinder bore and rod are meticulously cleaned before installation to prevent debris from damaging the new seals. Avoid using sharp tools that could nick or scratch the seal lips during insertion.
Inspect the cylinder rod for any scoring or damage, and clean the cylinder bore thoroughly before installing the new seal kit.
