This is a Bucket Cylinder Seal Kit designed for the Volvo EC80D excavator, ensuring the integrity of the hydraulic cylinder. Manufactured to high standards, it prevents hydraulic fluid leaks and maintains proper cylinder pressure for optimal bucket operation. Operators may notice hydraulic fluid leaks around the cylinder rod, slow or jerky bucket movements, or a loss of lifting/dumping force when this kit fails.

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.
Visible hydraulic fluid leaks around the cylinder rod are the most common initial symptom of a failing seal kit. This can progress to internal leakage, causing the bucket to drift down under load or move sluggishly. Continued operation with leaking seals can lead to cylinder damage and reduced hydraulic system efficiency.
Carefully clean the cylinder bore and piston rod before installing new seals to prevent damage from debris. Ensure all seals are properly oriented according to the installation diagram.
Inspect the cylinder rod for scoring or damage and clean the hydraulic fluid reservoir and filter when replacing cylinder seals.
