This is a hydraulic cylinder seal kit designed to maintain the integrity of the boom cylinder in Volvo excavators. It utilizes high-quality NBR rubber and robust metal components to prevent internal and external leakage, ensuring optimal hydraulic system performance compared to worn seals. 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 sluggishness in boom operation or minor external fluid seepage. If ignored, the leakage will worsen, leading to a noticeable loss of hydraulic pressure and reduced lifting capacity. Continued operation with a failing seal kit risks internal cylinder damage and potential hydraulic system contamination.
Ensure the cylinder rod is clean and free of any burrs or damage before attempting to install the new seals. Avoid using excessive force or sharp tools, which can easily nick or cut the new seals during installation.
Inspect the cylinder rod for scoring and the hydraulic fluid for contamination when replacing this seal kit.
