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

9. Attach a suitable nylon lifting sling around wheel (18). 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.
