Mounting Wheels
56. Position a wheel on the hub from which it was
dismounted.
Refer to Figure 57
57. Start all lug nuts by hand. Choose a bolt stud to designate
position #1.
58. Torque in stages, setting each lug nut to the specified
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)
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 machine axle is still elevated, test both the service
and the parking brake systems.
60. Hitch a tractor equipped with trailer brake remote.
Connect the braking systems. Put the tractor in Park, but
release any brakes that operate the trailer service brakes.
61. Have someone spin one brake-equipped machine wheel,
and stand clear.
62. Slowly engage the tractor service brakes. If the wheel
does not stop spinning, this may merely indicate 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 machine 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 machine braking.
66. Spin the first wheel again. Engage the machine 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
machine.
69. Check tire inflation, set parking brakes, and lower
machine onto its own wheels.
