Walk wheeled tractor system maintenance

Wheeled tractor walking system maintenance and maintenance, 2019 - 05 - 02 check regularly adjusted according to the technical requirements for the tractor to strict inspection and the front wheel hub, wheel bearing clearance the adjustment. （ 1) Front wheel bearing clearance checking and adjusting the correct front wheel bearing clearance of 0. 1 - 0. 2 mm, when more than 0. 5 mm, should be adjusted. From the adjustment, the front axle, the front wheel off the ground, in turn, remove the dust cover, cotter pin, screw adjusting nut, until the elimination of bearing clearance, return 1/10 circle; Turn the front wheel, wheel flexible and loose has no obvious phenomenon, it indicates that the adjustment is correct.
