Decrease the Track Tension
1. Use the bucket as a support to lift the track on one side.
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.
