Product Description

Cummins QSL9 Engine Cylinder Liner Kit 4089963 For CLG450/CLG939E Excavator Parts 4941393 Tilt Cylinder Seal Kit


Oil consumption of all SANY models is within the normal range of 0.2% (2 litres of oil for every 1 dry litre of fuel burned).

1. The coordination of each component of the engine has a certain tolerance range. Differences in the assembly tolerances of these parts, even for the same type of machine, can lead to different fuel consumption.


2. Different operating conditions of equipment may cause differences in fuel consumption. The greater the engine load, the higher the temperature, the lower the oil viscosity, and the oil entering the combustion chamber will increase accordingly.


3. When the machine works in an inclined or uneven place, the oil in the oil pan shakes back and forth, constantly colliding with the high-speed rotating crankshaft, forming fog discharged from the exhaust port to the outside, thus increasing fuel consumption.

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.
