VIII. SERVICE AND MAINTENANCE

BOLT TORQUE Wheel Bolts

To install wheel and tire assembly on the Torque Hub®, lubricate studs with anti-seize grease. Align the wheel bolt holes with the Torque Hub ® studs and mount the wheel on the hub.

NOTE:

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

Start all of the lug nuts on and tighten them until they are just snug. Following the torque sequence in figure 8.48, 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 sequence to 150 dry foot-pounds and again finally to 180 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 preferably, place a suitable wedge between the tire and the ground.

Check lug nut torque immediately after receiving machine and every 50 hours thereafter.

Lower the machine and resume operation. Recheck torque after 30 minutes of operation. For torquing purposes the wheel studs should be clean and lubed.
