Should rubber tracks be replaced in pairs?

Expert Answer

Yes, in most cases rubber tracks should be replaced in pairs to keep the machine balanced, maintain even traction, and prevent one side from doing more work than the other. Replacing both tracks at the same time is usually the safest choice for mini excavators, compact track loaders, and similar machines.

A new track paired with a worn track can create uneven tension and different rolling resistance side to side. Common signs are steering drift, one side tracking tighter, vibration, poor straight-line travel, and uneven undercarriage wear. If the machine has been running with one badly worn track, also inspect the sprockets/segments, rollers, idlers, and tensioning system before installing new rubber tracks.

There are cases where a single-track replacement can be acceptable, such as when one track is damaged unexpectedly and the opposite track still has plenty of life left. Even then, the decision should be based on the actual condition of both tracks, not just visible tread: check cracking, exposed cords, broken lugs, missing guides, and whether the bars or rubber have become brittle or stretched. If wear is clearly uneven, pairing the replacement is usually the better long-term option.

A common mistake is replacing only one track and ignoring the rest of the undercarriage. Another is fitting a new track while the machine still has worn sprockets or misaligned components, which can shorten the life of the new part.
