The diagnosis and troubleshooting section of this manual has been prepared to help with proper diagnosis. Repair
time and downtime, as well as repair costs, can be reduced if needless disassembly and replacement of steering
gear parts is avoided. Before removing the steering gear from the chassis, you must be certain that the hydraulic
supply system is operating properly and that all mechanical components are in good repair.
The Sheppard integral power steering gear is a precision machined assembly and care must
be taken during repair to keep it free of dirt and foreign material. All internal parts must
be handled carefully to avoid damage to machined surfaces. Nicks or burrs can cause dam-
age to mating parts and must be removed with a fine hand stone before reassembly. Work-
ing on a soft cardboard or plywood-surfaced workbench is best. Follow disassembly pro-
cedures as required.
Refer to the "Pitman Arm Removal" instructions in the "Common Procedures" section of this manual. Follow
these instructions carefully and remove the tab lock retainer and pitman arm.
Remove the rubber sector shaft boot
Remove the mounting bracket bolts and
separate the mounting bracket from the
steering gear (if equipped) (Figure 85).
