Information

Before the quality Copeland discus piston is repaired, first remove the carbon material on the top of the quality Copeland discus piston by using a non-sharp metal blade or a non-metal scraper.

quality Copeland discus piston

When the quality Copeland discus piston pin hole is perpendicular to the piston pin hole and has a certain distance from the bottom surface of the piston skirt, measure its diameter with an outer micrometer. When replacing, first measure the diameter of the new piston and the inner diameter of the cylinder, and calculate the fitting clearance between the new piston and the cylinder. If applicable, the piston can be replaced; if the diameter of the piston exceeds the service limit, the cylinder can be repaired by boring.

Strain and corrosion of quality Copeland discus piston

Improper maintenance of the engine, such as: broken piston rings, hard iron mixed in the cylinder, etc., the surface of the quality Copeland discus piston will be strained. If it is a minor strain, it can be polished with finer sandpaper or a grindstone; if it is a serious strain, the piston needs to be replaced. If there is too thick carbon deposits or high temperature on the top of the piston, part of the metal on the piston will adhere to the cylinder wall, or there will be small melting pits on the top of the piston. The former is called sticking, and the latter is called ablation. If the pull corrosion is not serious, you can use a grindstone or finer sandpaper to clean the sticking or ablation area, and the piston should be replaced if it is serious. Sometimes the piston also breaks, most of which occur on the top of the piston or near the piston pin hole, and the mechanical load is large. When the piston is broken, it should be replaced in time to avoid accidents.

The inner diameter was measured and plugged using a percent inner diameter meter. The measured piston value is greater than the limit value, indicating that the piston pin hole is seriously worn and should be replaced.

Use an outer micrometer to measure the outer diameter of the piston pin at the upper, middle and lower positions of the piston pin, and according to the JI value of the measurement result, it is indicated that the excessive wear of the quality Copeland discus piston pin should be replaced. When replacing the quality Copeland discus piston or piston pin, the clearance between the piston pin hole and the piston pin should meet the standard requirements.
