This is a bucket cylinder seal kit, designed to replace worn seals within the hydraulic cylinder responsible for actuating the excavator's bucket. It is manufactured to meet original equipment specifications, providing a reliable seal compared to a kit with inferior materials that would quickly fail. Operators may notice hydraulic fluid leaks around the cylinder rod, slow or jerky bucket movements, or a loss of bucket holding pressure when this seal kit is worn.
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.
The first sign of a failing bucket cylinder seal kit is often visible hydraulic fluid leakage from the cylinder rod or barrel. If ignored, the leakage will worsen, leading to reduced hydraulic system pressure and sluggish or unstable bucket operation. Continued use risks significant hydraulic fluid loss, potential damage to the cylinder bore and rod, and extended equipment downtime.
Thoroughly clean the cylinder bore and rod before installing new seals to prevent damage and ensure a proper seal. Ensure all seals are seated correctly and not twisted during installation to avoid immediate leakage.
Inspect the cylinder rod for scoring or damage, and check the condition of the cylinder barrel and piston for wear before installing the new seal kit.
