This is a bucket cylinder seal kit, essential for maintaining the integrity and performance of the excavator's main lifting cylinder. It contains all the necessary seals, O-rings, and wipers to prevent hydraulic fluid leakage and contamination, ensuring smooth and powerful bucket operation. Unlike worn seals that allow fluid bypass and reduced cylinder efficiency, this kit restores optimal seal performance. Operators may observe slow bucket movement, leaks around the cylinder rod, or a loss of hydraulic pressure in the bucket circuit when this kit is required.
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 failing bucket cylinder seals is typically visible hydraulic fluid leakage from the cylinder rod. This can quickly lead to sluggish or jerky bucket movements and a reduction in lifting force. If ignored, the cylinder may lose its ability to hold position, potentially causing uncontrolled lowering of the bucket, which poses a risk to personnel and equipment.
Thoroughly clean the cylinder barrel and piston rod before installing the new seals to prevent contamination and ensure a leak-free seal. Ensure all seals are properly seated and lubricated with clean hydraulic oil.
When replacing the bucket cylinder seal kit, inspect the cylinder rod for any scoring or damage and check the hydraulic fluid for signs of contamination.
