Check Lug Nut Torque
Check lug nut torque at 10 hours, 50 hours and
every 200 hours thereafter. Tighten to 88-95 ft•lb
(108-129 N•m) as needed.
Check Track Tension
Check track tension at startup and every 10
hours and adjust as needed. Track is correctly
tensioned when measurement between track and
straight edge (2) is 1/2 in (13 mm).
To adjust:
1. Park machine on smooth, flat surface.
2. Lay straight edge on top of track, spanning
from sprocket to front idler roller.
3. Clean track cylinder zerk (1). Pump MPG into
zerk until distance between track and straight
edge (2) is 1/2” (13 mm).
4. Test: Drive forward one track length and
check tension again.
• If tension is too loose, repeat step 3
above.
• If tension is too tight, loosen fitting on
grease cylinder and allow a small
amount of grease to discharge from
cylinder. Tighten fitting and test again.
