Start By:
a. Remove the final drive. See Disassembly and Assembly, "Final Drive - Remove".
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
Do not use threaded rods that have not been hardened as tooling with
hydraulic cylinders. The maximum rated tonnage should be stamped
on one end of the puller studs. Do not use threaded rods that have not
been stamped with the rated tonnage.

circumference of the cone evenly. Do not stop the torch and heat the cone in any one place.
If the hub is heated excessively during bearing removal 150 °C (300 °F), the future service
life may be reduced. If the bearing cone is heated in any one place to a temperature above
120 °C (248 °F), the heat treatment will be destroyed. A bearing failure is probable if the
bearing is used again.
