Excavator crawler device is a built-in flow meter, if not both the same flow, 230 used excavators, then there is doubt. Another method of detection is to control the operation of the excavator on the ground 10 meters, 215 used excavators, if running in a straight line, it is possible to know the same on both sides of mobile equipment operating condition is good. See also the same inversion ring gear and reverse bearings. Under normal circumstances, the upper part of the engine can be smoothly and accurately reverse parking, only a few or no errors. For small excavators, its reverse ring gear and reverse bearing the same machine should have the same number of long life, and therefore had to pay attention to any of this, some questions.
