2021 Good Quality Crawler Excavator Undercarriage Parts - Bulldozer undercarriage parts – Jinjia

The various components of a crawler undercarriage — links, pins, bushings, sprockets, rollers, idlers, shoes and frames —seem relatively simple, straightforward parts. But make no mistake; when these components are assembled into a system that supports and propels a track-type machine, the dozer undercarriage becomes a complex mechanism, which, experts tell us, might account for half (or more) of a crawler dozer’s lifetime repair bill.

Obviously, we can’t address the crawler undercarriage in as much detail here. But we can review some basics about design, wear factors (for chains and sprockets, in particular), maintenance practices and operating techniques, which, taken together, might help you curb undercarriage wear and, consequently, trim undercarriage costs.

In broadest terms, dozer undercarriages can be categorized by how the pins and bushings are lubricated — or not lubricated. The pins and bushings, of course, create the hinges in the track chain that allow the chain’s links to bend around the crawler’s sprockets and idlers.
