This is a hydraulic cylinder seal kit designed to maintain the integrity of the boom cylinder in Volvo excavators. It utilizes high-grade NBR rubber and durable metal components to prevent internal and external leakage, ensuring optimal hydraulic system performance. Failure of these seals typically manifests as a slow-moving or drifting boom, visible hydraulic fluid leaks around the cylinder rod, and a loss of lifting power.
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 seal failure include a noticeable drop in boom speed or a tendency for the boom to drift downwards when not actively being operated. If left unaddressed, the leakage will worsen, leading to a significant loss of hydraulic pressure and reduced lifting capacity, potentially immobilizing the equipment.
Ensure the cylinder bore and rod are meticulously cleaned before installation to prevent damage to the new seals. Avoid using sharp tools to insert the seals, as this can easily cause nicks or tears.
Inspect the cylinder rod for any scoring or pitting that could compromise the new seals' performance and consider replacing the rod wiper seal as well.
