How many years can I use the chassis parts for other excavators? Because you ignored these details!

The proper maintenance of the chassis part of the excavator is especially important!

For sprocket:

The side of the drive wheel must always be at the rear. If the drive wheel is walking forward, it not only has abnormal wear on the drive ring gear and the chain track, but also may cause problems such as early cracking of the X frame. Regularly open the walking motor guard to clean the dirt inside. When the motor protection plate protects the motor, it also stores some dirt and gravel inside. The moisture in the soil may corrode the joint of the motor oil pipe, and the gravel may interfere with the oil pipe, causing wear and leakage. oil. When replacing the final transmission oil, the excavator should be parked on a flat ground, and the final drive should be transferred to the oil draining port, which is at the bottom and perpendicular to the ground. When refueling, tighten the oil drain nut and refuel from the upper fuel filler port. The oil can flow out.

For trakc roller :

In daily work, the roller should be avoided in the mud, water and snow for a long time; After the completion of the work every day, the single-sided crawler should be propped up, and the traveling motor should be driven to remove the dirt and other debris on the crawler; Especially when working in winter, be sure to keep the rollers dry. If the roller has water, it will form ice at night; when the second day of operation moves the excavator, the floating seal between the roller and the shaft will be scratched by contact with the ice, resulting in oil leakage.

For carrier roller: 

Usually keep the X-slope bevel platform clean, do not let the soil pile up too much; otherwise it will cause the carrier roller to rotate. As with the roller, avoid the sprocket wheel soaking in the mud. The carrier roller is filled with lubricating oil at one time. If the oil leaks, only the new carrier roller can be replaced.

For track group:

Avoid walking on gravel for a long time. Long-term walking can easily cause bending deformation of the track shoe, and even cracking of the track plate bolt fixing. The track tension should be appropriate, and the maximum vertical distance between the track plate and the long bar is generally between 15-30mm. Excessive tightening of the track will cause early wear of the chain links, ring gears and guide wheels.

For Idler:

The tension spring assembly consists of a spring and a tensioning cylinder that requires periodic oil draining and oiling. Draining oil: When the tensioning cylinder grease nozzle is released at most one turn, the butter will be squeezed out from the oil draining port; the operator must stand on the side to prevent the grease mouth from being ejected and causing casualties. Filling the oil: Tighten the grease fitting with a grease gun until the track is tensioned to the proper position.
