The CAT 318 is a mid-size hydraulic excavator manufactured by Caterpillar, engineered for high productivity and versatility across a range of heavy-duty construction, utility, and excavation applications. It is distinguished by its outstanding digging and lifting performance, making it particularly effective for tasks that require robust hydraulics and precision, including trenching, foundation excavation, grading, demolition, and material handling. The operating weight of the CAT 318 generally falls within the range of 42,000 to 46,000 pounds (19,051 to 20,865 kilograms), contingent upon the specific configuration, counterweights, and attachments utilised.

The CAT 318 Final Drive helps restore steady travel power, smooth turning and reliable track movement for your CAT 318 excavator. If your machine is slow to walk, loses drive on one side, or shows heat around the travel hub, the track drive may be starting to fail.
This replacement hydraulic travel motor transfers power through the undercarriage, giving your excavator the control it needs for trenching, lifting, grading, site preparation and general construction work. A correctly matched drive motor can improve machine response, reduce strain on related hydraulic parts and help keep downtime under control.
