This is a bucket cylinder seal kit specifically designed for Volvo excavators, ensuring the proper functioning of the bucket hydraulic cylinder. It is constructed from durable materials that resist wear and hydraulic fluid degradation, providing a reliable seal that prevents leaks and maintains consistent cylinder pressure, unlike a worn kit that allows fluid bypass. Operators may observe a slow or uncontrolled lowering of the bucket, a loss of digging force, 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.
A failing bucket cylinder seal kit will typically manifest as the bucket slowly drifting down when not actively being controlled by the operator. If the issue is not addressed, the bucket may begin to lose holding pressure, making it difficult to maintain position during operation, and eventually leading to a significant reduction in digging efficiency. Continued operation can cause increased wear on the cylinder bore and rod, potentially requiring more extensive repairs.
Carefully clean the cylinder bore and rod to remove any dirt or debris that could damage the new seals during installation. Ensure all seals are oriented correctly before insertion.
Inspect the bucket cylinder rod for scoring or pitting, and check the hydraulic fluid for signs of contamination or degradation.
