Mounting Wheels
56. Position a wheel on the hub from which it was dis-
mounted.
Refer to Figure 142
57. Start all lug nuts by hand. Choose a bolt stud to des-
ignate position #1.
58. Torque in stages, setting each lug nut to the speci-
fied torque in the order shown in the figure:
Stage 1: 27-33 N-M (20-25 ft-lbs)
Stage 2: 74-80 N-M (55-60 ft-lbs)
Stage 3: 114-127 N-M (85-95 ft-lbs)
Note: This staging and ordering of tightening is strongly
recommended to ensure that the drum is not driven
out-of-round.
59. Repeat step 57 and step 58 for each wheel.
Test and Adjust Brakes
While the drill axle is still elevated, test both the service
and the parking brake systems.
60. Hitch a tractor equipped with trailer brake remotes.
Connect the braking systems. Put the tractor in Park,
but release any brakes that operate the trailer ser-
vice brakes.
61. Have someone spin one brake-equipped drill wheel,
and stand clear.
62. Slowly engage the tractor service brakes. If the
wheel does not stop spinning, this may merely indi-
cate that the self-adjusters have not yet seated.
Cycle a second time.
63. Check for unusual noises and failure to brake. Check
that the wheel spins freely with brakes released.
64. Spin another drill wheel. Stop it with the tractor
brakes. Check braking action. The self-adjusters
may already be seated for this and the remaining
wheels.
65. Release all tractor braking that engages drill braking.
66. Spin the first wheel again. Engage the drill parking
brake for that side. With fresh brake linings, it may be
necessary to adjust the hand brake handle to
achieve over-center brake-set detent with acceptable
effort.
67. Spin and test brake the other wheel on that side.
68. Repeat step 66 and step 67 for the other side of the
drill.
69. Check tire inflation, set parking brakes, and lower
drill onto its own wheels.
