Failure Symptoms

Early indications of a failing boom cylinder include slow or jerky boom operation and a slight loss of lifting power. If ignored, the cylinder may develop significant hydraulic leaks, leading to a complete loss of boom control. Continued operation risks damage to other hydraulic components or uncontrolled equipment movement.

Installation Tip

Before connecting hydraulic lines, ensure the cylinder rod is clean and free of any dirt or debris that could contaminate the hydraulic system. Avoid over-tightening the mounting bolts, which can distort the cylinder or mounting points.

Service Note

When replacing a boom cylinder, inspect the hydraulic pump, control valves, and all associated hydraulic lines for signs of wear or leakage.
