Fig. 2L-31 Stub Shaft Installation
CAUTION: Do not allow the stub shaft to disengage
from the valve body pin. If disengagement occurs, the
spool valve will extend too far into the valve body, allow
the damper O-ring to expand into the valve bodygrooves
and prevent valve withdrawal. Ifdisengagement occurs,
attempt to remove the valve using a pull and turn mo
tion. If this fails, proceed as follows: First be sure the
spool valve isfree to rotate, then place the valve body on
a fiat surface with the notched end of the valve body
facing upward. Tap the spool valve with a wood orplas
tic rod until the damper O-ring is cut and remove the
valve. Replace the damper O-ring and reassemble the
valve body. Be sure all pieces of the cut O-ring are
removed before assembly.
Pitman Shaft and Side Cover
Cleaning and Inspection
Clean the shaft and cover with solvent and wipe them
dry with lint free cloths.
Inspect the side cover bearing and mating surfaces for
wear, distortion, scoring, or distortion. Replace the
cover if it exhibits any of these conditions.
Inspect the pitman shaft bearing and seal surfaces
and sector teeth for cracks, wear, pitting, or scoring (fig.
2L-32). Inspect the adjuster screw for looseness, dam
aged threads, or distortion. Replace the pitman shaft if
any of these conditions are noted. However, light scor
ing, corrosion, or scratches on the shaft surfaces may be
removed using crocus cloth.
Inspect the pitman shaft nut threads and master
spline for damage (fig. 2L-32). If either of these surfaces
are damaged, replace the shaft.
Rack Piston and Wormshaft
Disassembly
(1) Remove wormshaft, lower thrust bearing, and
bearing races from rack piston.
(2) Cut and remove seal ring and backup O-ring
from rack piston. Discard seal ring and O-ring.
(3) Remove ball return guide clamp attaching
screws and remove return guide clamp.
(4) Place rack piston on clean cloth and remove two-
piece ball return guide, arbor tool, and ball bearings.
Cleaning and Inspection
Clean all components with solvent and dry them using
filtered compressed air.
Inspect the wormshaft for wear, scoring, pitting, dis
tortion, nicked threads, or cracks. Replace the worm-
shaft if it exhibits any of these conditions. Inspect the
rack piston for scored, pitted, or nicked ball bearing
grooves. Replace the wormshaft and rack piston as an
assembly if either part is damaged.
Inspect the exterior surface of the rack piston for
wear or scoring and be sure the seal ring seat is clean
and free from burrs.
