Start By:
a. Remove the cab.
b. Remove the center drive shaft.
c. Separate the steering frame lock.
When you are using hydraulic cylinders and puller studs, always ensure
that the rated capacity of the puller stud meets or exceeds the rated
capacity of the hydraulic cylinder. If the puller stud does not meet or
exceed the rated capacity of the hydraulic cylinder, a sudden failure of
the puller stud could occur. The sudden failure of the puller stud could
result in personal injury or death.
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, "Dealer Service Tool
Catalog" for tools and supplies suitable to collect and contain fluids on
Cat products.
Dispose of all fluids according to local regulations and mandates.
Note: Put identification marks on all hoses, on all hose assemblies, on all wires, and on all tube
assemblies for installation purposes. Plug all hose assemblies and all tube assemblies. This helps
to prevent fluid loss, and this helps to keep contaminants from entering the system.
