Built to deliver strong hydraulic performance, fuel efficiency, and long-term durability, the Komatsu PC310 is widely trusted by operators working in demanding job site conditions.
This excavator series is available in several models, including the PC310LC-7, PC310LC-8, PC310LC-10, and PC310NLC variants. Depending on the machine configuration and attachments, the operating weight generally ranges from approximately 31 to 33 tonnes. The Komatsu PC310 Final Drive provides excellent digging power, smooth swing operation, and reliable travel performance, making it suitable for a wide range of heavy excavation tasks.
Crawler excavators such as the Komatsu PC310 rely heavily on their final drives and travel motors for machine mobility, torque transfer, and overall operational efficiency. Over time, components including floating seals, bearings, planetary gears, and hydraulic motors may wear due to continuous heavy workloads, contaminated oil, and harsh operating environments.
