In the process of daily maintenance and repair, the accurate setting of screw torque is one of the key factors to ensure the stable operation and prolongation of the service life of the equipment. Different models and specifications of Carter excavators have different screw torque requirements, so be sure to refer to the official maintenance manual of the corresponding model excavator before operation to obtain accurate values. For example, a main pump screw torque for a Carter 320D excavator may be 300ft-lbs, while a Carter 349DL hydraulic cylinder set screw torque may need to reach 500ft-lbs. These figures are examples only and do not represent actual values, so please be sure to check the specific vehicle model for confirmation. In order to ensure the safety and efficiency of excavator operations, it is essential to measure and apply screw torque correctly. The use of a professional torque wrench and tightening according to the specified torque value can effectively prevent mechanical failure problems caused by overtightening or loosening. In summary, understanding and mastering the specific torque requirements of the screws in each part of the Carter excavator is a necessary professional knowledge and skill for every excavator operator and maintenance technician, so as to ensure that each screw is as effective as it should be. Please note that the torque requirements may also be adjusted for different working environments, working conditions, screw materials and other factors, and it is recommended to regularly maintain and check the excavator and update the relevant data information in real time.
