This bucket cylinder seal kit is essential for maintaining the integrity of the hydraulic cylinder that actuates the excavator's bucket, preventing fluid leaks and ensuring proper operation. Manufactured from durable, high-performance sealing materials, it offers superior resistance to wear and contamination compared to worn or damaged seals. Operators may notice hydraulic fluid leaking from the cylinder rod, slow or jerky bucket movements, or a loss of lifting/dumping 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.
The first sign of a failing bucket cylinder seal kit is often visible hydraulic fluid leakage around the cylinder rod. This can progress to slower or less powerful bucket movements, and the bucket may drift down under load. If left unaddressed, the leakage can lead to a significant loss of hydraulic pressure, compromising the machine's ability to perform its primary digging and loading functions.
Carefully clean the cylinder bore and rod before installing new seals to prevent damage from burrs or debris. Ensure all seals are seated correctly and not twisted during installation.
Inspect the cylinder rod for scoring or damage, and check the cylinder barrel for any signs of wear or deformation when replacing the bucket cylinder seals.
