This seal kit is designed to replace worn seals within the bucket cylinder of Volvo excavators, ensuring proper hydraulic pressure retention and smooth operation. It is manufactured to meet stringent OEM standards, providing a durable seal that prevents internal and external leakage, unlike degraded original seals. Operators may notice a loss of bucket curl or tilt force, slow cylinder movement, or external hydraulic fluid leaks when this 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 sluggishness in bucket curl or tilt functions. If ignored, the cylinder may lose significant lifting or digging power, and external fluid leaks will become more pronounced. Continued operation with failed seals can lead to internal cylinder damage and potential loss of hydraulic system pressure.
Thoroughly clean the cylinder bore and rod before installation to prevent debris from damaging the new seals. Ensure seals are oriented correctly before pressing them into place to avoid immediate leakage.
Inspect the cylinder rod for any scoring or damage that could compromise the new seals' integrity.
