How do you use an excavator track tension tool to check and adjust track tension?

Question

VANROCK Track Solutions · Accepted Answer

An excavator track tension tool is used to measure track sag or set track tension more consistently, but it does not replace the machine’s adjustment procedure. The correct tension depends on the excavator model, undercarriage condition, and whether the track is steel or rubber; if the track is too tight or too loose, it can cause accelerated wear, poor ride, or track derailing.

Start by parking on level ground, cleaning the undercarriage, and following the machine manual for the correct measuring point. On many excavators, the track is checked at the center of the lower run with the machine weight on the track, then adjusted through the grease tensioner if required. A tool can help you measure sag more repeatably, especially when comparing both sides.

Practical checks matter as much as the measurement:
• If the track is overly tight, look for high resistance, fast wear on rollers, idlers, and sprockets.
• If the track is too loose, check for thrown tracks, uneven tracking, or excessive slap.
• If the tension changes quickly after adjustment, the grease cylinder, seals, or idler system may need attention.
