HOW TO MAINTAIN UNDERCARRIAGE OF BULLDOZERS AND EXCAVATORS

Undercarriage parts have a huge effect on working performance and walking performance of bulldozer and excavator. Maintenance is a key for walking-speed of bulldozers and excavators.

There are some tips for maintaining undercarriage parts for bulldozers and excavators as follows:

No.1: Front Idler is in the front of the track frame. The function is to prop the track up and guide the track to wind correctly. Besides, Front Idler and Track Adjuster work together to maintain a certain degree of tension on the track. So during working and walking, should keep Front Idler running ahead, which can avoid the wear of the track. Meanwhile, Track Adjuster can reduce the vibration and shedding of the track during walking.

No.2: Carrier Roller is above the track frame. The function is to carry and keep the track moving in a straight line. If Carrier Roller has a breakdown, Track Link will not work properly. Carrier Roller is added lubricating oil at once. If oil spills occur, you will have to replace this part. Therefore, you should keep the track frame clean. Don't let the accumulation of dirt and gravel hamper its work.

No.3: During working, Track Roller cannot be immersed in mud for a long time. After working, should support the track on one side. Then, Drive walking motor to get rid of dirt and gravel. In winter, should keep Track Roller dry because there is a floating seal between the outer roller of Track Roller and the shaft. If there is water, it will freeze at night. When the excavator is walking the next day, the floating seal is in contact with ice to cause oil spill. When Track roller is damaged, can cause many faults, such as walking deviation, walking weakness, and so on.

No.4: Sprocket or segment is in the back of the track frame. Because it is fixed on the track frame, it has no shock absorption function. If sprocket moves forward, it will not only cause the abnormal wear of Sprocket and the track, but also have adverse effects on the track frame. The track frame may have early cracking.

No.5: Track Chains are generally used for mechanical transmission and traction. They are usually made of steel chains. They should be well maintained during normal use. The tightness of the track chains should not be too tight or too loose, which will damage the track links. Also Chains should keep clean to avoid sunshine and rain, and to avoid touch acid-base solvents and other substances. If the chain is worn seriously, the chain should be replaced to ensure good results, so that it can prolong its life.

Bulldozer undercarriage track chain should be lubricated in time in order to make the chain work more smoothly and quickly and reduce wear and tear.attention old track chains can not be mixed with new track chains. It would impact and damage the chains.
