Timely lubrication

Running gear lubrication is very important, a lot of roller bearing caused by "burned" subscription fee is not found in time because of the oil spill. Generally believe that the following five possible leak: due to the baffle ring and shaft between the o-ring bad or damaged, the baffle ring between the lateral and axial leakage; Because of floating seal ring is poor contact or o-ring defects, from lateral baffle ring and roller (roller, guide wheel, driving wheel) between the oil; Because of the roller (roller, guide wheel, driving wheel) between the bushing and the o-ring, oil between sleeve and roller; Refueling because of screw loosening or tapered plug seal hole damage, oil plug in oil; Because of the bad o-ring, oil between block cover and roller. Therefore, at ordinary times should pay attention to check the above parts, and according to the different parts of the lubrication cycle to add, change regularly.

Keep in a guide wheel position

Of the guide wheel has serious effect on other parts traveling mechanism, thus adjust the clearance between the guide roller guide and crawler frame is right (correct) extend the life of the walking mechanism. Adjustment in between the guide plate and bearing pads to revise, if the gap is big, down gasket; Small gap, increase the gasket. Clearance is 0.5 ~ 1.0 mm, maximum permissible gap is 3.0 mm.

Bolt and nut tightening in time

When walks the organization is loose, easily broken or missing, triggered a series of failures. Daily maintenance and maintenance should check the following bolt: the installation of the roller and wheel bolt, driven gear block installation bolt, crawler plate bolts installation, roller plate installation bolt, diagonal brace TiaoTou bolt installation. Main bolt tightening torque reference illustrations of the various models.
