Excavator maintenance taboo 1, with emery cloth polishing pad for some of the less experienced repairman, scraping the higher a difficult task, due to the scraping technique is difficult to master, so the pad is not easy to meet the technical requirements. For this reason, some people in the replacement bearing, in order to increase the contact area between bearing and crankshaft grinding it with emery cloth instead of scraping. This method is highly undesirable actual maintenance of Tai'an used mini excavators prices because abrasive emery cloth on the hard, but bearing alloy was softer, so it is easy when sanding grit embedded in the alloy, the diesel engine will work journal accelerated wear and shorten the life of the crankshaft. 2, bolts too tightly construction machinery in the disassembly process used mini excavators Tai'an price, many parts of the bolts are all specified torque requirements, such as gear box, cylinder heads, wheels, connecting rods and parts of the former Bridge tightening torque in the specification has special provisions, must not arbitrarily change. But many people mistakenly believe that the use of some tight would be safer, but over-tighten the screws or bolts may cause breakage Tai'an used mini excavator price, but also may be due to the threaded slider and cause malfunctions. 3, tire pressure is too high wheel construction machinery tire inflation pressure is an important factor in determining their life and work efficiency. Tire pressure is too high or too low will affect their life, while not conducive to safe driving, especially in the hot summer months. Inflatable scientific criteria should be: a standard tire pressure as a reference, as the temperature changes, adjust the tire pressure slightly fishes. For example: in summer and winter should be lower than 5% -7%, in consideration of the high summer temperatures, gas heat, pressure increased Tai'an used mini excavator price, contrary winter must meet the standard pressure or slightly below.泰安嘉 and Heavy Machinery Co., Ltd. How excavator proper maintenance? Youth and excavators, as well as machine to play the biggest role in the stage. This time though the parts have been out of the run-in period, are lubricated with the place, but not without restraint has been increased workload, the best you can have a maintenance schedule.
