(1) Maintain appropriate tension on the track

(2) Maintain the alignment of the idler position

The misalignment of the guide wheel has a serious impact on other parts of the walking mechanism, so adjusting the gap between the guide wheel guide plate and the track frame (correcting misalignment) is the key to extending the life of the walking mechanism. When adjusting, use the gasket between the guide plate and the bearing to correct it. If the gap is large, remove the gasket; Small gap, add shims. The standard clearance is {{0}}.5-1.0mm, and the maximum allowable clearance is 3.0mm.

(3) Flip over the track pin and pin sleeve at the appropriate time

During the wear process of the track pin and the pin sleeve, the track pitch is gradually elongated, causing poor engagement between the drive wheel and the pin sleeve, resulting in damage to the pin sleeve and abnormal wear of the drive wheel tooth surface, which can cause hunting, tapping, and impact, greatly shortening the service life of the walking mechanism. When the pitch cannot be restored by adjusting the tension, it is necessary to flip the track pin and pin sleeve over to obtain the correct track pitch. There are two ways to determine the timing of flipping the track pin and pin sleeve on site; One method is to determine the moment when the track pitch is extended by 3mm; Another method is to check the moment when the outer diameter of the pin sleeve wears out by 3mm.

(4) Tighten bolts and nuts in a timely manner

(5) Timely lubrication

The lubrication of the walking mechanism is very important, and many supporting wheel bearings are burnt out, resulting in reimbursement due to oil leakage that was not detected in a timely manner. It is generally believed that there may be oil leakage in the following 5 areas: due to poor or damaged O-ring between the retaining ring and the shaft, oil leakage occurs from the outer side of the retaining ring to the shaft; Due to poor contact of the floating seal ring or defects in the O-ring, there is oil leakage between the outer side of the retaining ring and the supporting wheel (support wheel, guide wheel, drive wheel); Due to poor O-ring between the supporting wheel (supporting wheel, guide wheel, drive wheel) and the bushing)
