Installation Procedure

Show/hide table

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.

Note: Threaded rods cannot be used with hydraulic cylinders as tooling.

Note: The side of the equalizer bar assembly that must be oriented toward the front of the machine is stamped with the component part number and the word FRONT.
