SERVICE AND MAINTENANCE
G. BOLT TORQUE
127
WHEEL BOLTS–
If you do not have the proper equipment to mount a
tire, let your local qualified tire sales/service dealer mount the tire for you. The
tire should be mounted on the rim according to figure 127-1 for best traction
and tread cleaning action. To install wheel and tire assembly on the wheel
hub lubricate studs with an anti-seize grease. Align the wheel bolt holes with
the wheel hub studs and mount the wheel on the hub.
Start all of the lug nuts and tighten them until they are just snug. Following the torque sequence in figure
127-3, first turn each lug nut to a torque value of 120 dry foot– pounds. Use slow, even pressure on the torque
wrench. Quick or jerky movements cause inaccurate values. Repeat the same sequences to 150 dry foot–
pounds and again finally to 400 to 500 dry foot– pounds.
If the wheel turns during lug nut torquing, lower the machine to
the ground just enough for the tire to touch and prevent rotation or
more preferably, place a suitable wedge between the tire and the
ground.
Lower the machine and resume operation. Recheck torque after
30 minutes of operation.

NOTE:
To achieve even torquing consistency, the tire should be
completely off the ground.
