Maintenance method

Sumitomo excavator swing motor maintenance is one of the important steps to ensure the proper operation of the excavator and extend its service life. Here are some general guidelines for Sumitomo excavator swing motor maintenance:

Cleaning: It is very important to clean the swing motor regularly. Use a high-pressure water gun or air compressor to clean the dust and dirt on the surface of the motor. Make sure that no damage is caused to the motor during cleaning.
Lubriion: Lubriion of the swing motor is key. Check and replace the lubriing oil regularly according to the manual of the Sumitomo excavator. Make sure to use the right lubriing oil for the swing motor and follow the specified replacement cycle.
Fasteners: Check the fasteners on the swing motor regularly, including bolts and nuts. Make sure they are tight and not loose. If any loose fasteners are found, tighten or replace them in time.
Check the electrical connections: The swing motor is usually connected to the electrical system of the excavator. Check the electrical connections regularly and make sure they are tight and reliable, without looseness or corrosion. If any problems are found, repair or replace the connections in time.
Regular inspections: It is very important to check the overall condition of the swing motor regularly. Check for any leaks, abnormal noises or abnormal vibrations. If any abnormality is found, you should contact a professional technician for inspection in time.
Please note that the above is a general guide and the specific maintenance steps may vary depending on the model and manufacturer. It is strongly recommended to refer to the user manual of the Sumitomo excavator or consult a professional technician for detailed maintenance guidelines for your specific excavator model.

Theory

The Swing motor is a key component of the excavator's slewing mechanism. It converts the oil pressure provided by the main pump into mechanical energy and inputs it to the reducer. Its working performance will directly affect the rotation speed, driving torque, and rotation of the entire machine. Parking and parking brakes are key to determining the productivity of the entire machine. After the excavator has been working for a long time, the swing motor often appears weak in rotation and unstable in rotation. At this time, it is necessary to replace the internal parts based on the test results.
