Cummins QSM11 Engine Cylinder Liner Kit 4022532 For Construction Machinery Parts Boom Cylinder Seal Kit

Working principle:

The piston is the "heart" of the automobile engine, which bears alternating mechanical and thermal loads. It is one of the key components in the engine with extremely poor working conditions. The role of the piston is to withstand the gas pressure, through the piston pin transfer to the connecting rod, drive the crankshaft rotation. The top of the piston is also part of the combustion chamber. ​

Excavator maintenance:

Check items before starting the engine. Check the coolant level (add water); Check engine oil level, refueling; Check the fuel level (add fuel); Check the hydraulic oil level (add hydraulic oil); Check whether the air filter element is blocked; Check the electrical wiring; Check whether the horn is normal; Check the bucket lubriion; Check the water and sediment in the oil-water separator.

(2) Every 100 maintenance items. Boom cylinder head pin; Boom foot pin; Cylinder rod end of boom cylinder; Sticky cylinder cover pin; Boom, bucket rod connecting pin; Rod end of rod cylinder; Bucket cylinder head pin; Half rod connecting pin; Bucket rod, bucket cylinder cylinder rod end; Bucket cylinder head pin; Sticky connecting pin; Check the oil level in the rotary box (refueling); Drain water and sediment from the fuel tank.

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 lubriing 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.
