SINOTRUK HOWO WD615 engine series Piston Ring early over wear reason

Sinotruk Howo Parts
(Howo WD615 Engine Parts- piston ring assembly)

1. Piston ring reasons: (1) piston ring material does not meet the technical requirements of organization, loose tissue (2) the low hardness of the piston ring does not meet the requirements (3) poor thermal stability of the piston ring, microstructure changes

2. Cylinder Liner reasons: (1) liner diameter does not meet the requirements, too large or too small (2) cylinder liner hole roughness does not meet the requirements, the film is not easy to form (3) liner verticality, circularity does not meet the requirements. We recommand you to use our original cylinder liner:

3. Other parts: (1) air filter, Oil Filter quality is not good, a lot of dust or oil into the cylinder with too much impurities (2) friction matching improperly.

4. Oil aspects: (1) poor quality oil (2) poor quality fuel, lead content is high, the formation of abrasive combustion products, and cause abrasive wear.

5. Repair: (1) When cleaning, the cleanliness is not enough, the cylinder body with sand or iron and other impurities (2) the piston ring or piston size selection is not appropriate (3) assembly of moving parts, with the gap, the bolt torque does not meet Claim.

6. Use: (1) the engine temperature is not normal, too high, too low will aggravate the wear parts. (2) engine idling or high-speed movement time is too long, overloaded (3) overhaul, the engine does not go according to the provisions of normal and maintenance.

7. Other aspects: (1) Flared piston ring groove wear (2) Inadequate combustion, the cylinder body, the piston groove on the serious wear and tear (3) Piston groove roughness does not meet the requirements (side wear) (4) Residual corrosion
