This is a bucket cylinder seal kit designed to maintain hydraulic pressure and prevent fluid leakage within the bucket cylinder assembly of Volvo excavators. It is manufactured to meet stringent OEM quality standards, ensuring superior sealing performance compared to worn or damaged seals that lead to gradual pressure loss and reduced cylinder responsiveness. Operators may notice slow or jerky bucket movements, external hydraulic fluid leaks around the cylinder rod, or a loss of lifting/dumping force 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.
Initial signs of failure include a slight sluggishness in bucket curl or dump functions. If ignored, the problem will progress to noticeable external hydraulic fluid leaks from the cylinder rod and a significant reduction in lifting capacity. Continued operation with failing seals can lead to increased wear on cylinder components and potential system contamination.
Ensure all old seal material is completely removed from the cylinder grooves before installing the new seals. Avoid using sharp tools that could scratch the cylinder rod or bore during installation.
Inspect the cylinder rod for scoring or damage and clean the hydraulic system thoroughly before installing the new seals.
