This is a boom cylinder seal kit designed to replace worn seals within the boom cylinder assembly of Volvo excavators. It is constructed from high-quality, durable materials that resist wear and hydraulic fluid degradation, ensuring a tight seal unlike compromised original seals. Operators will typically observe hydraulic fluid leaks from the boom cylinder, slow or jerky boom movement, or a loss of lifting capacity when these seals fail.
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 boom cylinder seals is often visible hydraulic fluid leakage around the cylinder rod. If left unaddressed, the leaks will worsen, potentially leading to a gradual loss of hydraulic pressure and reduced lifting performance. Continued operation with leaking seals can cause contamination of the hydraulic fluid and damage to the cylinder bore.
Carefully inspect the cylinder rod and bore for any scratches or scoring before installing new seals, as imperfections will cause premature failure. Avoid using sharp tools when removing old seals or installing new ones to prevent damage to the cylinder components.
Inspect the hydraulic fluid for contamination and consider replacing the hydraulic filter when rebuilding a cylinder.
