The oil change frequency for a Cat 920 excavator depends on several factors, including the operating environment and the type of oil being used. For severe operating conditions, such as high temperatures or frequent use, the oil should be changed every 500 hours or 3 months, whichever comes first. In normal operating conditions, the oil can be changed every 1000 hours or 6 months.
It is also important to check the oil level regularly, and to add oil as needed to maintain the proper level. The oil should also be checked for any signs of contamination, such as water or dirt. If any contamination is found, the oil should be changed immediately.
Cat 920 excavators can use either SAE 15W-40 or SAE 20W-50 oil, depending on the ambient temperature and climate conditions. For additional information on oil type, oil change intervals, and other related topics, refer to the operator's manual for your specific Cat 920 excavator model.
