Decrease the Track Tension
NOTICE!
Remove gravel or mud buildup between the
sprocket and the track before reducing track
tension.
NOTICE!
Dispose of used grease in accordance with all
applicable environmental regulations. Failure to
do so could result in damage to the environment.
1.
Slowly open the grease valve (2) 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.
2.
When the track sag is within specification, tighten the
grease valve to 44 lb-ft–59 lb-ft (60 N•m–80 N•m).
3.
Rotate the track one full revolution. Check track
tension to confirm adjustment.
4.
Position the adjuster cover and tighten the fasteners.

CAUTION
• Allow the final drive to cool before servicing. Hot
oil may cause burns or other serious injury.
• Wear safety goggles, gloves, and other personal
protective equipment (PPE) to prevent serious
injury.
• The final drive oil may be under pressure.
Remove the plugs slowly to prevent injury.
Failure to follow these precautions could result in
injury.
