This is a Boom Cylinder Seal Kit designed to maintain hydraulic pressure and prevent fluid leakage within the boom cylinder assembly of Volvo excavators. It is manufactured to stringent quality standards, ensuring superior sealing performance compared to worn or damaged seals that allow fluid bypass. Operators may notice a loss of boom lifting power, slow or jerky boom movement, or visible hydraulic fluid leaks around the cylinder rod 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 drift of the boom when not under load or a minor fluid weep around the cylinder rod. If ignored, the leakage will worsen, leading to a noticeable reduction in lifting speed and power. Continued operation with compromised seals can result in increased hydraulic system temperature and potential damage to other components.
Ensure the cylinder rod is thoroughly cleaned and free of any burrs or debris before installing new seals to prevent immediate damage. Avoid using sharp tools that could nick or cut the seal lips during insertion.
Inspect the cylinder rod for any signs of scoring or pitting, and check the hydraulic fluid for contamination before installing the new seal kit.
