SMCS - 4006-011-FR
Removal Procedure
Start By:
a. Connect the steering frame lock. Refer to Disassembly and Assembly, "Steering Frame LockSeparate and Connect".
b. Release hydraulic system pressure. Refer to Disassembly and Assembly, "Hydraulic System Pressure - Release".
c. Remove the Tire and Rim. Refer to Disassembly and Assembly Manual, "Tire and RimRemove and Install".
d. Remove the Final Drive Planetary. Refer to Disassembly and Assembly Manual, "Final Drive Planetary - Remove".
Personal injury can result from hydraulic oil pressure and hot oil.
Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system.
Make sure all of the attachments have been lowered, oil is cool before removing any components or lines. Remove the oil filler cap only when
the engine is stopped, and the filler cap is cool enough to touch with your bare hand.
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.
NOTICE
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.
Refer to Special Publication, NENG2500, "Caterpillar Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Caterpillar products.
Dispose of all fluids according to local regulations and mandates.
Note: Put identification marks on the line and all parts for installation purposes. Plug the lines. This will help to prevent fluid loss and this helps to keep contaminants from entering the system.
1. Drain the oil from the axle housing into a suitable container. The capacity of the axle housing is 8 L (2.1 US gal).
