The LTMG BTL388 backhoe loader existing maintenance and repair specifications are a summary of many years of practical experience and are scientific and reasonable. The LTMG BTL388 backhoe loader wear of excavators that are often in a wide range of load changes is greater than that of excavators that work continuously and stably. shanmon 388h In general, the engine used by the generator has a longer service life than that used by bulldozers, excavators, etc. The normal working load mainly depends on the use of the excavator by the operator. and the outer race and inner race of the bearing will rotate synchronously, which will lead to excessive wear between the bearing and the bearing seat. xgma xg765 backhoe Excessive bearing wear will cause friction between the rotor and stator of the generator, resulting in overheating of the topwin twb388a backhoe loader generator and instability of the voltage and current of the generator.Check the generator bearing for lack of oil or poor lubricationFirst, xgma xg765 backhoe pay attention not to work under the maximum load that the excavator can bear, and use the maxbull MBL388-3S backhoe loader. need change engine oil normally , about 3mothns change one time . www.haiqinmachinery.com
