BENEFITS AND FEATURES
The Cat 3054CA engine has been designed to meet U.S. EPA Tier 2 and EU Stage II emission regulations. This engine incorporates a time-proven mechanical governor and a low-pressure fuel injection system that are major contributors to the improvement of fuel system robustness, high fuel efficiency, and ease of troubleshooting. High filtration performance from the primary filter incorporating a water separator and a secondary filter also help to improve fuel filtration system reliability.
Automatic Engine Control and Fuel Delivery With a net power of 82 kW (110 hp) the 318D L Series 2 has been designed with fuel economy in mind and burns approximately 3% less fuel when compared with the larger 318D L depending on application.
Economy Mode Available as a standard feature, economy mode allows you to balance the demands of performance and fuel economy while maintaining the breakout forces and lift capacity enjoyed at standard power.
High efficiency and performance with low effort and precise control.
BENEFITS AND FEATURES
Outstanding Performance The 318D L Series 2 hydraulic system is designed for high efficiency and performance. The new compact design utilizes shorter tubes and lines to reduce friction and pressure drops, resulting in a more efficient use of power.
- Hydraulic snubbers at the rod end of the boom cylinders and both ends of the stick cylinders cushion shock, reduce sound, and increase cylinder life.
- A hydraulic cross-sensing system uses two hydraulic pumps under all operating conditions, improving productivity with faster implement speeds and quicker, stronger pivot turns.
Boom and Stick Regeneration Circuit The boom and stick regeneration circuit saves energy during boom-down and stick-in operation, increasing efficiency and lowering operating cost.
Easy Operation Operators do not need to learn different modes. An automatic boom and swing priority function automatically selects the best mode based on joystick movement.
Excellent stability and maneuverability.
BENEFITS AND FEATURES
Caterpillar uses advanced engineering and software to analyze all structures, creating a durable, reliable machine for robust applications. More than 70 percent of the structural welds are robotic and achieve additional penetration over manual welds. These structural components and undercarriage are the backbone of the machine’s durability.
Carbody Design X-shaped, box-section carbody provides excellent resistance to torsional bending. Robot-welded track roller frames are press‑formed, pentagonal units that deliver exceptional strength and service life. Integral to the track roller frame are the standard idler and center guards, which help maintain track alignment when traveling or working on slopes.
Grease Lubricated Track Grease lubricated track seals protect the track link and deliver long track link pin and bushing inner wear life.
Travel Motors Travel motors with automatic speed selection let the 318D L Series 2 automatically change up and down from high and low speeds in a smooth, controlled manner.
Performance, reliability and durability.

BENEFITS AND FEATURES
An extensive range of Cat work tools for the 318D L Series 2 includes buckets, compactors, grapples, multi-processors, rippers, crushers, pulverizers, hammers and shears. Each is designed to optimize the versatility and performance of your machine.
Couplers Quick couplers allow one person to change work tools in seconds for maximum performance and flexibility on a job site. One machine can move rapidly from task to task, and a fleet of similarly equipped machines can share a common work tool inventory.
CW Dedicated Coupler The CW quick coupler can pick up any work tool and is equipped with a wedge-style locking system that fits the quick coupler tight to the tool hinges. Due to the tapered wedge design, there won’t be any play during its entire life. Also it is interchangeable with different machine classes. The CW is highly suitable for harsh applications such as demolition and quarries.
Center-Lock™ Pin Grabber Coupler* Center-Lock is the pin grabber style coupler and features a patent-pending locking system. A highly visible secondary lock clearly shows the operator when the coupler is engaged or disengaged from the bucket or work tool. *Offering varies for different regions.
Buckets Cat Buckets and Cat Ground Engaging Tools (GET) are designed and matched to the machine ensuring optimal performance and fuel consumption.
General Duty Buckets (GD) These buckets are designed for digging in low-impact, moderately abrasive materials such as dirt, loam, gravel and clay.
Heavy Duty Buckets (HD) HD buckets are a good starting point when application conditions vary. Especially when conditions include mixed dirt, clay and sand and gravel.
Severe Duty Buckets (SD) These buckets are best suited to highly abrasive applications such as shot rock, sand stone and granite.
Hydraulic Kits Caterpillar offers field-installed hydraulic kits that are uniquely designed to integrate Cat Work Tools with Cat excavators. Hoses and tubes are pre-made, pre‑shaped, and pre-painted to make installation quick and easy.
