What are track guards and do I need them?

Expert Answer

Track guards are steel plates or guides bolted to the track frame to keep the track chain centered and prevent it from walking sideways off the rollers. In most cases, they also help shield rollers, seals, and the chain from rocks, mud, sticks, and packed debris.

You usually need them if your machine works on slopes, rough rock, demolition sites, forestry, or anywhere side-loads and debris can push the track out of alignment. They are less critical on flat, clean ground, but even there they can reduce wear and lower the risk of derailment. Some machines use shorter front and rear guards, while others need longer or additional guards depending on the undercarriage design and application.

The main signs you may need track guards, or that your current ones are not working well, are repeated tracking problems, shiny rub marks on the chain, chipped or bent guard edges, or damage around roller flanges and seals. Guards that are bent inward, loose, or worn too close to the chain can actually create extra friction, so they should be inspected whenever you check track tension and general undercarriage wear.

When choosing guards, match them to the machine model, track type, and working conditions rather than guessing from appearance alone. Important fit points include frame mounting position, clearance to the chain, and whether the machine is set up for full-length or partial guarding. Avoid running without guards in severe conditions, and avoid installing guards that contact the track under load.
