This is a bucket cylinder seal kit designed to replace the worn seals within the hydraulic cylinder responsible for actuating the excavator's bucket. Manufactured to meet stringent OEM standards, this kit ensures a tight seal and prevents hydraulic fluid leakage, unlike a damaged or incomplete seal. 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 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 most immediate symptom of failing bucket cylinder seals is visible hydraulic fluid leakage around the cylinder rod. This can progress to a loss of hydraulic force, causing the bucket to drift or fail to hold its position under load. If left unaddressed, significant fluid loss can lead to system contamination and potential damage to the cylinder and hydraulic pump.
Carefully clean the cylinder bore and piston rod before installing new seals to prevent damage. Ensure all seals are properly seated and lubricated before reassembly.
Inspect the cylinder bore for scoring or damage, and check the hydraulic fluid for contamination when replacing the bucket cylinder seal kit.
