INITIAL 10 HOURS
Track tension check and adjustment
Check the track tension after the first 10 h on a new machine or if new tracks have been installed. After the initial 10 h
check, the track tension should be checked every 50 h thereafter. For this procedure, the tracks, rollers, idler wheels,
debris guard, and final drive sprockets must be clean of dirt and debris.
Track tension check
1. Park the machine on firm level surface.
2. Raise, block, and support machine properly until the
tracks are about 50 mm ( 2.0 in ) off the surface.
3. Measure from the bottom of the center roller wheel (1)
to the lower track top surface (2) . The allowable track
sag is 12 – 19 mm ( 0.5 – 0.75 in ).
