Product Description

Perkins C7.1 EFI Engine Cylinder Liner Kit For E320D2 E320E Bulldozer Engine Parts 3747389 Steel Piston Rings


Daily maintenance method of excavator engine


Maintain water tank regularly to improve cooling system function. The sediment in the engine water tank limits the circulation of coolant, leading to overheating of the engine and even engine damage, so it is necessary to remove rust, scale and other sediments in time. Check whether the temperature controller, water temperature gauge and water temperature sensor are in good condition, check whether the radiator is unobstructed, check the tension of the wind Angle belt, and the working condition of the fan blades and water pump, so as to ensure the normal operation of the engine and extend the engine life. Overall life. When a car engine is working, fuel burns in the cylinder to produce exhaust gas, which is discharged from the engine.

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.
