This is a complete boom cylinder assembly, a critical hydraulic actuator responsible for lifting and lowering the boom on excavators. Manufactured to precise tolerances with robust seals and high-strength materials, it ensures smooth, powerful, and leak-free operation compared to a worn or damaged cylinder. Operators may experience slow or jerky boom movements, or a noticeable drift when the boom cylinder begins to fail.
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.
Early signs of boom cylinder failure include a slight hesitation or sluggishness when raising or lowering the boom. If ignored, the cylinder may start to drift downwards under load, or exhibit jerky movements, reducing operational efficiency and control. The most severe consequence is a complete loss of boom control, posing a significant risk to the operator and surrounding environment.
Ensure the cylinder rod is clean and free of any burrs or damage before retracting it into the barrel. Avoid forcing the cylinder into position if the mounting pins do not align easily.
Inspect the hydraulic pump, control valves, and all associated hydraulic lines and fittings for proper function and leaks.
