The Engine liner set is a collaborative precision friction vice. Replacement must be carried out as a set, because the combination of new and old parts will cause uneven gaps. Its principle is based on precision machining and fluid dynamic pressure lubrication, relying on oil to form an oil film in the gap to avoid dry friction.

Common faults and diagnosis

When the engine liner set kit wear is serious, the following typical symptoms usually appear:

1. Burning engine oil, blue smoke: the piston ring is worn or stuck, the seal fails, and the oil plunges into the combustion chamber.
2. Insufficient power and difficult acceleration: the wear of the piston and cylinder liner causes the cylinder to be sealed tightly and the compression pressure to drop.
3. Difficulty in starting: The cylinder pressure is too low, and it is difficult to compress the mixed gas.
4. Engine noise: the gap between the piston and the cylinder sleeve is too large, and there may be a "knocking cylinder" sound; the wear of the piston pin may also produce abnormal knocking sound.
5. Too fast oil consumption: In addition to burning oil, it may also be caused by cylinder liner wear and oil.

Maintenance

1. Key check: During overhaul, it is necessary to measure the inner diameter of the cylinder liner, the diameter of the piston skirt, the cylinder gap, the opening gap of the piston ring, etc.
2. Standard torque: All bolts must be tightened with a torque wrench according to the manual.
3. Preventive maintenance: use high-quality engine oil and replace it regularly to keep the air filter and fuel system clean.
