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 meet stringent OEM standards, ensuring superior sealing performance compared to worn or damaged seals that lead to gradual loss of lifting power. Operators may notice slow-crawling boom movements, external hydraulic fluid leaks around the cylinder rod, or a general decrease in the machine's lifting capacity 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.
Slow or jerky boom movements are often the first sign of a failing boom cylinder seal kit. If ignored, the leakage will worsen, leading to a noticeable loss of hydraulic pressure and reduced lifting capacity. Extended operation with compromised seals can lead to premature wear on other hydraulic components.
Ensure the cylinder bore is completely clean and free of debris before installing new seals to prevent immediate damage. Do not use sharp tools to pry or force the seals into place, as this can easily nick or cut them.
Inspect the cylinder rod for any scoring or damage, and check the hydraulic fluid for contamination.
