2979133 Cylinder — Cat 311d Lrr 311F Lrr

This component is a cylinder, essential for the hydraulic system's operation, enabling linear motion for actuators and implements. It is manufactured to meet high-pressure and durability standards, offering superior sealing and structural integrity over a worn or damaged cylinder. Operators may observe slow or jerky hydraulic movements, fluid leaks around the cylinder rod, or a complete loss of hydraulic function.

Failure Symptoms

The first sign of a failing cylinder is often a noticeable decrease in lifting or pushing force, or slow, erratic movement of the associated implement. If left unaddressed, internal seal failure can lead to significant hydraulic fluid loss and external leaks, potentially causing system overheating. Continued operation risks damage to the hydraulic pump and other system components due to low pressure or contamination.

Installation Tip

Thoroughly clean the cylinder mounting points and ensure the rod is free from any nicks or burrs before installation. Avoid forcing the cylinder into position; ensure proper alignment to prevent binding or seal damage.

Service Note

Inspect hydraulic hoses, fittings, and the hydraulic fluid for contamination or degradation when replacing a cylinder.
