Measure track sag to the grouser tip. If you measure to the shoe, you'll adjust chain tension too tightly.

The most controllable variable affecting undercarriage cost is track-chain adjustment, which requires measuring track sag accurately every day. Tight tracks wear up to three times faster than properly adjusted ones.

Most track chain should sag 2 inches, measured from a straight edge laid across the grousers to the grouser tip at the low point (check your operator manuals for each machine's specific recommendation). First let the machine roll to a stop. Then lay a straight edge over the grousers, and measure to the grouser tip.

To get a true reading, always measure and adjust chain tension under working conditions. Clean track, for example, will tighten up when mud starts packing in its sprockets.
