Maintenance cycle of engineering machinery castings

‌The maintenance cycle of engineering machinery castings mainly depends on the use and maintenance conditions, and usually fluctuates between a few months and a year. Engineering machinery operating in harsh environments has a shorter maintenance cycle due to greater wear; vehicles with regular maintenance can extend their service life and maintenance cycle; high-quality engineering vehicles are more durable and have longer maintenance intervals.

Specific time range of maintenance cycle
‌Every 100 hours: Check the boom, dipper connecting pin, cylinder head pin and other components.
‌Every 250 hours: Replace the oil in the final drive box, check the tension of the fan belt and air conditioning compressor belt, replace the oil in the engine oil pan and the engine filter, etc.
‌Every 500 hours: Replace the fuel filter, clean the radiator, replace the hydraulic oil filter, replace the oil in the final drive box, etc.
‌Every 1000 hours: Check the shock absorber housing, etc.
