This seal kit is designed to replace worn or damaged seals within the adjustment cylinder of Volvo excavators, ensuring proper hydraulic pressure retention and preventing fluid leaks. Manufactured to meet original equipment standards, it provides a reliable seal comparable to new components, unlike degraded seals that lose elasticity and crack. Operators may observe hydraulic fluid leaks around the adjustment cylinder, or a loss of cylinder holding pressure, indicated by slow drifting or inability to maintain position, when this seal kit is needed.
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.
The first sign of failing adjustment cylinder seals is often visible hydraulic fluid leakage around the cylinder rod or at the cylinder end caps. If ignored, the leaks will worsen, leading to a gradual loss of hydraulic pressure and potentially causing the cylinder to drift or fail to hold its position. Prolonged operation with leaking seals can lead to contamination of the hydraulic system and premature wear on cylinder components.
Thoroughly clean the cylinder bore and rod before installing new seals to prevent damage and ensure a proper seal. Be careful not to nick or cut the seals during installation, as even minor damage will compromise their sealing ability.
Inspect the cylinder rod for scoring or damage, and check the hydraulic fluid for contamination when replacing the adjustment cylinder seals.
