| Illustration 3 | g00515258 |
Stretch a string over the grousers between the sprocket and the front track idler. Measure the distance from the string to the top of the grouser at the maximum measurement.
The track sag is correct when the sum of dimensions (1) and (2) equals 90 ± 10 mm (3.5 ± 0.4 inch) .
