How to maintain our Undercarriage parts (track roller, carrier roller, track chains, track link,sprockets, segment, idler, track shoe, track bolt and nut) for Bulldozer and Excavator

Proper maintenance of the undercarriage is an essential aspect when it comes to preserving the service life of an excavator or bulldozer. Depending on how intensively it is used, the undercarriage must undergo an undercarriage overhaul about every five years. As a rule, it is recommended to have an undercarriage inspection carried out on site beforehand to determine if a partial or complete overhaul is required. Not all undercarriage components wear at the same rate. Practical experience shows that a complete undercarriage overhaul is the most cost effective option in the long term.

When the carrier and track rollers are still in good condition, a partial undercarriage overhaul could be a cost-saving option. A partial undercarriage overhaul consists of replacing the sprockets (segment), track chains(links), tack bolts and nuts, as these components are inextricably linked. Fact is that the track chain, and therefore also the sprockets(segment), wear out significantly faster if they run over rollers that have been in service for some time and have worn away by more than 50 percent. For that reason (unnecessary early wear and tear) it is often the smarter choice to immediately renew the top and bottom rollers. This will ultimately result in the lowest cost peroperating hour.
