Failure Symptoms

Initial signs of a failing lift cylinder may include a slight drift in the boom or bucket when holding a load. If ignored, the cylinder will progressively lose lifting capacity and may exhibit external fluid leaks. Continued operation risks uncontrolled descent of the implement, potentially damaging the equipment or causing injury.

Installation Tip

Ensure the hydraulic system is properly depressurized before disconnecting any lines to prevent fluid loss and potential injury. Avoid overtightening the hydraulic fittings, as this can damage the threads or the fitting itself.

Service Note

Inspect hydraulic hoses, seals, and the hydraulic fluid for contamination when replacing the lift cylinder assembly.
