1156429 Cylinder — Cat 320B

This is a hydraulic cylinder, a critical component in the machine's hydraulic system responsible for converting hydraulic pressure into mechanical force to operate various functions. Manufactured to high standards, it offers reliable performance and durability, unlike a worn cylinder that may exhibit leaks or slow operation. Operators might observe sluggish movement of hydraulic attachments, a loss of lifting power, or external fluid leaks when a cylinder is failing.

Failure Symptoms

The initial symptom of a failing hydraulic cylinder is often a noticeable decrease in the speed or force of the operated function. If left unaddressed, the cylinder may develop internal leaks, leading to 'drift' where the attachment slowly lowers or moves on its own. Severe failure can result in a complete loss of hydraulic function for that circuit, rendering the equipment unusable.

Installation Tip

Before removing the old cylinder, ensure the hydraulic system is safely depressurized to prevent injury. When installing the new cylinder, carefully align the mounting points to avoid stressing the rod or cylinder body.

Service Note

Inspect hydraulic hoses and fittings connected to the cylinder for leaks or wear, and check the hydraulic fluid level and filter condition.
