Decrease the Track Tension
1. Use the bucket as a support to raise the track on one
side. Swing the upper structure sideways, lower the
bucket to the ground, and raise one track off the
ground. Keep the boom-arm angle between 90° and
110° (1) with the bottom of the bucket on the ground.
2. Prepare the machine for service. See “Maintenance
3. Slowly open the grease valve (1) 1 to 1-1/2 turns while
observing idler movement. Grease should come out
from behind the grease valve.
NOTE:
If grease does not come out, slowly rotate the
track in both directions. When grease begins
to flow, stop and continue the adjustment.
4. When the track sag is within specification, tighten the
grease valve to 44
lb-ft–59
lb-ft (60 N•m–80 N•m).
5. Rotate the track one full revolution. Check the track
tension to confirm adjustment.
NOTICE!
Remove gravel or mud buildup between the sprocket and the track before reducing track
tension.
