Cleaning the tracks also goes a long way toward extending undercarriage life. "If they don't get cleaned on a regular basis, material will build up and it can prevent the rollers from turning, especially on the carrier rollers," says Pooley. "If they stop turning, they will get a flat spot on them and then the roller isn't usable."

Use a shovel to remove any mud and dirt buildup. Pay special attention to the top, which is more susceptible to buildup. Clean them at the end of every shift and before traveling long distances.

Severe applications
While a preventive maintenance program can increase the life expectancy of an undercarriage, there are certain applications where you may need to enhance that program and reduce the lead time between checks.

Use in very abrasive environments, such as in wet, sandy conditions, can shorten the life of components. For example, river or ditch clearing can expose tracks to water carrying sediment and other materials that can damage the undercarriage over time.

"When traveling, the undercarriage components will naturally increase in temperature," notes den Hoed. "If the machine enters water on a jobsite, there will be a rapid change in component temperature (expansion/contraction). This is very hard on moving joints."
