b. Used Gear (400 or more miles): Over-center torque
Disassembly of the major components within the gear
to be 4-5 lb. in. additional torque, but total over-
must be performed on a clean work bench. The work area,
center torque must not exceed 14 lb. in.
tools, and parts must be kept clean at all times. Refer to
Figs. 9-10 and 9-81 for parts nomenclature and location.
2. Record total over-center torque. This consists of
over-center, thrust bearing, and drag torque.

OVERHAUL OPERATIONS
The following procedure outlines the disassembly of the 2.
gear, overhaul of the individual components, and assem-
bly of the gear.
Rotate end cover retainer ring so that one end of the
ring is over the hole in the side of the housing. Force
the end of the ring from its groove and remove ring
(Fig. 9-82).
Turn the flexible coupling flange counter-clockwise
until the rack-piston just forces end cover out of
housing. Remove cover and discard "0" ring.
