This bucket cylinder seal kit provides all necessary seals and O-rings to rebuild a leaking Volvo excavator bucket cylinder. It is manufactured with high-quality sealing materials that resist hydraulic fluid and abrasion, ensuring a reliable seal unlike a worn or damaged original seal. Operators will typically notice hydraulic fluid leaking externally around the cylinder rod, or a loss of holding pressure causing the bucket to drift down when not actively being controlled.
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.
External hydraulic fluid leakage from the bucket cylinder rod is the most common symptom of worn seals. If ignored, the leakage will worsen, leading to a loss of hydraulic pressure and the bucket's inability to hold its position, potentially causing it to drift downwards. Continued operation with significant leakage can lead to system contamination and damage to the cylinder bore.
Thoroughly clean the cylinder bore and piston rod before installing new seals to prevent damage from debris. Ensure all new seals are properly lubricated with a compatible hydraulic fluid before insertion to prevent tearing.
Inspect the cylinder bore and piston rod for scoring or damage that could cause premature failure of the new seals.
