Engine and Hydraulics

The Cat® 323D L delivers the power and control that you need in order to get the job done quickly and efficiently in all applications.


Component Layout

The 323D L hydraulic system and component locations are designed to provide a high level of system efficiency. The main pumps, control valves and hydraulic tank are located close together to allow for shorter tubes and lines between components to reduce friction loss and pressure drops. The layout further provides greater operator comfort by placing the radiator on the cab side of the upper structure. This allows incoming air to enter the engine compartment from the operator side and hot air and corresponding engine sound to exit on the opposite side away from the operator. This reduces engine compartment heat and sound being transmitted to the operator.


Pilot System

The pilot pump is independent from the main pumps and controls the front linkage, swing and travel operations.


Hydraulic Cross Sensing System

The hydraulic cross sensing system utilizes each of two hydraulic pumps to 100 percent of engine power, under all operating conditions. This improves productivity with faster implement speeds and quicker, stronger pivot turns.


Auxiliary Hydraulic Valve

The auxiliary valve is standard on the 323D L. Control Circuits are available as attachments, allowing for operation of high and medium pressure tools such as shears, grapples, hammers, pulverizers, multi-processors and vibratory plate compactors.


Boom and Stick Regeneration Circuit

Boom and stick regeneration circuit saves energy during boom-down and stick-in operation which increases efficiency, reduces cycle times and pressure loss for higher productivity, lower operating costs and increased fuel efficiency.


Hydraulic Cylinder Snubbers

Snubbers are located at the rod-end of the boom cylinders and both ends of the stick cylinders to cushion shocks while reducing sound levels and extending component life.


Operator Station

Designed for comfort, simple and easy operation, the 323D L allows the operator to focus on production.


Wipers

Pillar-mounted wipers increase the operator’s viewing area and offer continuous and intermittent modes.


Structures

Caterpillar® excavators are designed to handle the most rugged operating conditions while providing long life and value.


Booms and Sticks

Designed-in flexibility to help bring higher production and efficiency to all jobs.


Work Tools - Attachments

The 323D L has an extensive selection of work tools to optimize machine performance.


Service and Maintenance

Simplified service and maintenance features save you time and money.


Complete Customer Support

Cat dealer services help you operate longer with lower costs.
