This seal kit is essential for maintaining the integrity of the bucket cylinder in Volvo excavators, preventing hydraulic fluid loss and contamination. Manufactured to precise standards, it offers superior sealing and wear resistance compared to compromised original seals. Operators may observe external hydraulic fluid leaks around the bucket cylinder, slow or uncontrolled bucket movements, or a loss of digging force 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.
External hydraulic fluid leaks originating from the bucket cylinder rod are the primary indicator of seal failure. This leakage will worsen over time, leading to a gradual decrease in bucket lifting capacity and potentially jerky or uncontrolled cylinder movement. If not addressed, significant fluid loss can impair the entire hydraulic system's performance and lead to component damage.
Thoroughly clean the inside of the cylinder barrel and the piston rod before installing the new seals to prevent damage and ensure a proper seal. Carefully orient each seal according to its specific groove to avoid improper seating.
Inspect the bucket cylinder rod for any scoring or damage, and check the hydraulic fluid for contamination when replacing the bucket cylinder seal kit.
