This is a Bucket Cylinder Seal Kit designed to maintain the integrity of the hydraulic bucket cylinder in Volvo excavators. Manufactured to meet rigorous quality specifications, these seals prevent internal hydraulic fluid leakage and external contamination, unlike worn seals that allow fluid loss and dirt ingress. Operators may observe a loss of bucket curl force, slow or uncontrolled bucket movements, or visible hydraulic fluid leaks around the cylinder rod 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.
The first indication of a failing bucket cylinder seal kit is a reduction in the force and speed of the bucket's curling and dumping actions. If not addressed, this will lead to slower cycle times, potential loss of holding pressure on the bucket, and visible hydraulic fluid leaks. Continued operation risks internal cylinder damage and reduced excavation efficiency.
Before installing the new seals, carefully inspect the cylinder rod for any nicks, scratches, or wear that could damage the new seals upon installation. Ensure all seal grooves are meticulously cleaned and free of old seal material or debris.
When replacing the bucket cylinder seal kit, it is recommended to inspect the cylinder rod for straightness and surface integrity, and check the hydraulic fluid level and condition.
