A:Generally speaking, the following points should be noted from the perspective of use:               

1.Bearing clearance should be appropriate, too large impact, too small badlubrication, may burntile.

2.Bearing and journal surface quality and geometry should be strictly guaranteed.                        

3.Improve the lubrication quality, control the oil pressure, temperature and flow, and enhance the oil filter.                                                                                                                                     

4.Controlling the temperature of the diesel engine and working under thecondition of over-cooling and over-heating is unfavorable. On cold days, thediesel engine should be preheated before        starting, and turn the crankshaft byhand to enter the oil into the friction surface.
