This seal kit is designed to replace worn seals within the bucket cylinder of Volvo EC290 excavators, ensuring proper hydraulic pressure retention and smooth operation. It is manufactured to meet stringent OEM standards, providing superior durability and sealing performance compared to degraded or damaged original seals. Operators may notice slow or jerky bucket movements, or visible hydraulic fluid leaks around the cylinder rod as signs of a failing seal kit.
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 a failing bucket cylinder seal kit include slow or hesitant bucket movements and minor hydraulic fluid seepage. If ignored, the leakage will increase, leading to a loss of hydraulic pressure and reduced digging efficiency. Continued operation with a compromised seal kit can lead to contamination of the hydraulic system and potential damage to the cylinder bore.
Carefully inspect the cylinder rod for any imperfections before installing the new seals, as even minor damage can lead to premature failure. Avoid using excessive force when seating the seals to prevent damage to their lips.
Inspect the cylinder rod and bore for any signs of wear or scoring that could affect the performance of the new seals.
