During maintenance, manual scraping shall be avoided. The quality difference between the boring pad and the scraping pad is large, so it is necessary to repair the fit clearance between the bearing and the journal with the boring pad method. If it is necessary to repair the scraping pads, special attention should be paid to the material of the pads. Because the fit clearance between the shaft and the bearing mainly depends on the material of the journal and bearing. Example: The bending, twisting and double bending of the connecting rod will skew the piston in the cylinder, causing eccentric wear between the piston and the cylinder, connecting rod bearing and connecting rod journal.
Cause of failure
When the engine is working, the gas pressure in the cylinder always acts on the piston crown. Due to the effect of gas pressure, the piston and piston pin, the piston pin and the small end bushing of the connecting rod are compressed, and the connecting rod bearing and the connecting rod journal, the main bearing and the main journal are compressed with each other through the connecting rod. Because all the above power transmission parts have a certain mass, they have the tendency to maintain the original operating state, that is, the role of inertial force. In addition, the engine is overloaded, dry burning and other reasons, the connecting rod is bent, twisted or double bent.
