Product Description

KOMATSU 6D125 Yanmar Piston Ring For D50/D65 Excavator 6150-31-2112 for Construction Machinery Engine Parts


Examples of engine maintenance:


The engine has speed, but can not start, the starter can operate normally.


In general, if the engine has speed but cannot be started, you can follow the following steps to troubleshoot:


Step 1: Check the oil level.


Although this step is simple, it is inevitable that everyone is too invested in the work and forget to refueling. If the oil level is too low, the engine will not start normally;


The second step: check whether the oil circuit is unobstructed, whether the filter element is blocked.

No matter the machine is old or new, it is possible that the filter element is blocked, the oil-water separator is blocked, and the entire oil circuit is blocked. As it happens, this self-check can be done by ordinary users.


The third step: solenoid valve and relay damage failure (flameout solenoid valve and relay failure is one of the characteristics of the engine and starter do not rotate).


Step 4: The 1S timer is damaged


The damage of the 1S timer needs professional evaluation. We suggest you contact your local service.


After receiving the repair report, the engineer can go to the customer to assist in the investigation. After a series of checks, the 1S timer is damaged.

Application of 6D125 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.
