Installation Procedure

Show/hide table

Personal injury or death can result from improper lifting or blocking. When a hoist or jack is used to lift any part or component, stand clear of the area. Be sure the hoist or jack has the correct capacity to lift a component. Install blocks or stands before performance of any work under a heavy component. Approximate weights of the components are shown. Clean all surfaces where parts are to be installed.

1. Clean all parts and inspect all parts. If any parts are worn or damaged, use new AVSpare parts for replacement.

2. Use Tooling (C) and two suitable nylon lifting slings to place the axle on a suitable pallet fork with suitable cribbing. The weight of the axle is approximately 550 kg (1212 lb).

3. Detach the two nylon lifting slings from Tooling (C) before using the pallet fork to position the axle under the machine.

4. Reattach the two nylon lifting slings to Tooling (C). Use the attached lifting equipment to raise the axle to the chassis. Install the washers that were removed during the removal procedure before raising the axle in position to the machine. Refer to the note that was made during the removal procedure for the position of all the washers.

10. Attach a suitable nylon lifting sling around wheel (9). Attach the nylon lifting sling to a suitable hoist in order to support the wheel. The weight of the wheel without ballast is approximately 190 kg (420 lb).

    Note: Liquid ballast is installed in the tires of certain machines. Liquid ballast will greatly increase the weight of a wheel. You must be sure that the weight of the wheel will not exceed the lifting capacity of your lifting equipment. Refer to Operation and Maintenance Manual, "Tire Inflation Information" for additional information about the recommended weight of installed liquid ballast.

17. Tighten wheel nuts (8) in a cross pattern to a torque of 240 ± 40 N·m (177 ± 30 lb ft) and then turn an additional 60 degrees ± 5 degrees.

    Note: Check the wheel nut torque on new wheels and on repaired wheels after every ten service hours until the specified torque is maintained. Refer to Operation and Maintenance Manual, "Wheel Nut Torque - Check".

18. Repeat the Step 17 on the wheel nuts on the other end of the axle.
