This is a hydraulic cylinder seal kit designed to replace worn or damaged seals within the boom cylinder of Volvo excavators. It is manufactured to meet stringent OEM standards, ensuring a precise fit and reliable sealing performance that prevents internal leakage and maintains hydraulic system pressure. Failure of these seals can lead to slow or jerky boom movements, loss of lifting capacity, and visible hydraulic fluid leaks around the cylinder rod.
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 worn boom cylinder seals include a slight drift of the boom when holding a load or a noticeable decrease in lifting power. If ignored, the seals will continue to degrade, leading to progressively slower and less responsive boom movements and increased hydraulic fluid loss. The ultimate consequence is a significant reduction in the excavator's operational capability and potential damage to the hydraulic system from contamination.
Thoroughly clean the cylinder bore and rod before beginning to prevent contamination from damaging the new seals. Avoid using sharp tools that could nick or scratch the sealing surfaces during installation.
Inspect the hydraulic fluid for contamination and consider replacing the hydraulic filter when servicing the boom cylinder seals.
