This seal kit is designed to replace the worn seals within the bucket cylinder of Volvo excavators, ensuring proper hydraulic pressure and preventing fluid leakage. Manufactured to high standards, it provides reliable sealing performance, unlike degraded original seals that can lead to operational issues. Operators may notice a slow leak-down of the bucket when holding a load, external fluid leaks from the cylinder, or reduced bucket breakout force when these seals begin to fail.
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 may initially present as the bucket slowly lowering or losing pressure when holding a load. If left unaddressed, the leakage will increase, resulting in a significant loss of bucket force and visible hydraulic fluid leaks. This can impair the machine's digging and dumping efficiency and potentially lead to damage to the cylinder or hydraulic system.
Carefully inspect the cylinder rod for any damage or rough spots that could compromise the new seals. Ensure the seals are seated squarely in their grooves without twisting.
Check the bucket cylinder rod for wear or damage, and inspect the hydraulic fluid for contamination.
