Off Vehicle

EQUIPMENT
When balancing wheels off the vehicle, use a balancer that pilots the wheel by its center hole. If the wheel tramp and vehicle vibration is not corrected by the off-vehicle balance, an on-vehicle balance may be needed. When performing an off-vehicle wheel balance, use one of the following electronic balancers to provide the proper wheel balance:
^ Rotunda Computerized Wheel Balancer 006-01755 or equivalent with Rotunda Wheel Adapter Set 078-00055 or equivalent.
^ Rotunda Computerized Wheel Balancer 006-01699 or equivalent with Adapter Plate 006-01640 or equivalent.

PROCEDURE
1. Raise vehicle on hoist. Remove lug nuts.
2. Remove wheel to be balanced. Mount wheel to balance machine.
3. The balance equipment should have been calibrated by a factory approved technician within the last 90 days.
4. The equipment mounting surfaces, cones, cone springs, wing nuts, and mounting cups must be clean and without damage.
5. All tire labels, stones, dirt and any other foreign material must be removed from the tire/wheel assembly. Particular attention should be paid to ensuring that the wheel mounting face and pilot hole are clean and free from foreign material.
6. The tire and wheel assembly must be mounted on the machine using a back mounted cone. Do not mount cone on front side of wheel.
7. The machine should be operated in the DYNAMIC mode.
8. The factory balance weights should not be removed from the wheel before checking the balance status.
9. Spin the tire and wheel assembly on the machine in accordance with the balance equipment manufacturers instructions.
10. Any tire and wheel assembly that shows a machine reading of 0.50 ounces or less in the DYNAMIC mode cannot be considered outside of factory specification when checked on field accurate balance equipment.
11. If DYNAMIC correction is required, remove and discard the factory balance weights. Respin the tire and wheel assembly and add new correction weights in accordance with balance equipment manufacturer's instructions. Never add more than 85 gram (3 oz) to either rim flange. Always recheck balance after weight is added.
12. Remove the tire and wheel assembly from the machine and mount onto the vehicle.
13. Lower the vehicle to the ground. Tighten the lug nuts to 85 Nm (62 ft. lbs.).
