OEMs that manufacture their own undercarriage, like Komatsu, typically offer several options that can help to lower operating costs. The idea is to maximize uptime by matching the application with the undercarriage product offering best suited to it.“One type of undercarriage does not fit all customer needs,” Nenne agrees. “For example, customers who regularly work in abrasive conditions might want to consider an extended life undercarriage with larger diameter bushing, profiled links and larger diameter rollers to help minimize wear and reduce cost.”
Nathan Horstman, product marketing manager, crawler dozers, John Deere Construction and Forestry, recommends working closely with local dealers to determine the undercarriage best suited for each scenario.
The working end of any crawler tractor is the blade. Inspect the top of the blade and spill guard and look for damage caused by rocks or heavy material. Inspect the corner bits on the bottom of the blade for wear and corrosion. Also inspect the cutting edge for remaining wear.
Komatsu advises customers who are using Tier 4 Final crawler tractors to learn how to properly idle and shut down the machines.
Uneven wear is one of the problems that can be corrected if caught early enough through periodic inspections. For example, if an operator is working on slopes in one direction only, the downhill track will wear quicker than the uphill track. That is an operator habit that can be changed to even out the wear patterns.

If working in a material that hardens as it dries out or freezes, cleaning the undercarriage daily will prevent the increased wear that occurs with the additional contact points.
Tracks should be checked daily or whenever ground conditions change to ensure the proper amount of track sag. Increased soil moisture, for example, can cause packing in the sprockets and a tight track, which can reduce wear life and lead to dry joints.
