Excavator maintenance:



(1) After the new machine works for 250 hours, replace the fuel filter element and additional fuel filter element; Check engine valve clearance.

② Daily maintenance; Check, clean or replace the air filter element; Clean the cooling system interior; Check and tighten the bolts of the track plate; Check and adjust track back tension; Check the inlet heater; Replace the bucket teeth; Adjust bucket clearance; Check the cleaning fluid level of the front window; Check and adjust the air conditioning; Clean cab floor; (Optional) Replace the circuit breaker filter element. When cleaning the inside of the cooling system, after the starter is fully cooled, slowly loosen the water injection cover to release the pressure in the tank, and then water can be released; Do not clean the engine while the engine is working, the high speed rotating fan will cause danger; When using coolant when cleaning or replacing coolant, the machine should be parked on a horizontal surface; Replace coolant and anticorrosive device according to Table 3. The ratio of antifreeze to water is specified in Table 4.

Type of coolant Internal cleaning and replacement cycle of the cooling system Replacement cycle of the anticorrosive device

Af-acl antifreeze (Super antifreeze) Every 2 years or every 4000 hours or every 1000 hours or when the coolant is replaced

Application of 4D31 Engine Cylinder Liner Kit:












Agricultural Machine



Advantage of Engine Cylinder Liner Kit

  • Greater resistance. Making liners separately from the engine block allows the use of special higher performance materials than those used for the construction of the block itself. Liners are generally made in special cast iron alloys containing elements with natural lubricating properties, like graphite. Other components are added like chrome, vanadium, and molybdenum to help ensure resistance to corrosion and wear caused by high temperatures.


  • Easier maintenance. When liners are worn they can be replaced more easily than changing an entire cylinder block.


  • Higher thermal conductivity. At operating temperatures the liners heat up more than the cylinders and must be able to expand in both diameter and length. If they were cast together with the cylinders, the resulting thermal loading would be high enough to fracture the materials.


  • Less risk of defects. The more complex a casting, the more difficult it is to achieve perfectly even surfaces with low residual stresses.
