11. Install 7 - 3/4” x 3-1/2” bolts with a hardened at
washer (#5) through the front holes on each side of
the U/C, shims if necessary, and the tractor frame.
15. Place controller from Step # 13 on the bolts
and thread a 3/4” ange nut on 4 of the top bolts
from Step #14. Attach the nut plate to the bottom
bolt and line up the top hex nuts to t in the nut
plate (#7). Note the orientation of the ange nuts.

vertical 20mm bolts to 432 ft-lbs.,
19. Torque the front 12 - 3/4” bolts on each side of the
undercarriage to 380 ft-lbs.
20. Torque all of the 3/4” bolts attaching the brackets to the
undercarriage to 380 ft-lbs. Alternate between the groups
of bolts when torquing. For example, torque the front left
bracket bolts, the rear right bracket bolts, rear left bracket
bolts, front right bracket bolts. Do the same routine for the
nal drive bracket bolts.
NOTE: Follow Steps #11-15 for the left side. After
Step #15, tighten the bolts until they are snug. If
necessary, add more shims until a gap of 1/16”
or less is on the right side. Proceed with Step
#11-14 for the right side.
13. If there is a controller for the drive shaft
sensor on the left inside frame of the tractor,
remove the original hardware and reattach
with the new hardware in Step #14-15. The
controller can t between the tractor frame and
the new nut plate.
