When to replace the undercarriage parts of your machine.

Replacement undercarriage parts focus on idlers, rollers, and sprockets. And most heavy equipment comes with both front and rear idlers. These large parts help the drive gears to rotate and move in the same direction and helps steer the heavy machinery correctly. Based on how the equipment is used, one idler may become more worn down than the other. However, we suggest you inspect both idlers for wear.

Sprockets are undercarriage parts that experience the most wear and tear on a daily basis. Sprockets are designed to mesh in with the rubber track to hold it in place and to move the track while the machine is in operation. Sprockets can lose their teeth or develop cracks that may cause the rubber track to loosen and jump out of place when the equipment is in motion.

Rollers will occasionally need to be replaced due to age, constant operation, or working in adverse and rocky conditions that increase the stress on the components until they have shifted out of place or have developed cracks.
