KOMATSU 4D95 Liner Kit Mitsubishi Piston For PC60-6 Excavator 6204-31-2121 for Construction Machinery Engine Parts

The engine is strong enough and works properly, while the machine digs slowly and weakly:

The hydraulic pump on the imported excavator is equipped with a pilot toothed soft pump. The pump is mainly involved in the variable hydraulic pump, as the pilot oil, open the stem of the multi-way valve, change its direction. If the wear of the gear pump can not establish a certain pressure or the safety valve on the gear pump can not be set to a certain pressure, the hydraulic pump will always be in a low flow state, the valve stem can not be completely reversed, so that the flow is insufficient, slow action, pressure, mining force is weak. For similar failures, just replace the pilot gear pump or reset the pilot safety valve.

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.
