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 superior durability and sealing performance compared to degraded or damaged original seals. Operators may notice slow or jerky bucket movements, or visible hydraulic fluid leaks around the cylinder rod as signs of a failing seal kit.
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 a failing bucket cylinder seal kit include slow or hesitant bucket curling or dumping actions. If ignored, the leakage will worsen, leading to a loss of hydraulic pressure and reduced lifting capacity. Continued operation with a compromised seal kit risks significant hydraulic system contamination and potential damage to other components.
Ensure the cylinder rod is thoroughly cleaned and free of any debris or burrs before attempting to install the new seals. Avoid using sharp tools that could scratch or nick the new seal lips during insertion.
Inspect the cylinder rod and bore for any signs of wear or damage that could prematurely wear out the new seals.
