This is a boom cylinder seal kit designed to restore the sealing integrity of the boom cylinder on Volvo excavators. It is manufactured to meet stringent OEM quality standards, ensuring superior durability and performance compared to worn or damaged seals that can lead to leaks and reduced boom lifting capacity. Operators may notice slow or uncontrolled boom raising/lowering, external hydraulic fluid leaks around the cylinder rod, or a loss of holding pressure when the boom is in a raised position.
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 slow-descending boom when holding a position or visible hydraulic fluid leaks from the boom cylinder rod. If ignored, the boom may drift down more rapidly, leading to reduced lifting performance and potential instability. Continued operation risks significant hydraulic fluid loss, overheating of the hydraulic system, and potential damage to the cylinder rod or barrel.
Before installing the new seals, ensure the cylinder rod and bore are meticulously cleaned to prevent any abrasive particles from compromising the seal integrity. Lubricate all seals with clean hydraulic fluid prior to insertion to avoid tearing.
Inspect the hydraulic fluid for contamination and consider replacing the hydraulic filter when servicing the boom cylinder seals.
