Assembly of Steering Valve
Replace all seals and o-rings with new ones. Make sure
the seals and o-rings remain seated correctly when
components are assembled.
Before assembling the steering valve, wash all parts in
clean solvent. Dry the parts with compressed air. DO
NOT wipe them dry with a cloth or paper as lint and dirt
may remain.
1. Put the four bolts into the fixture with the shortest
threaded end of the bolts through the fixture holes
(Fig. 63). Secure the bolts to the fixture with four 5/16-24
UNF nuts. Tighten the nuts to secure the assembly to
the fixture, but loose enough to turn the bolts and
facilitate stacking of components.
2. If the bushing was removed from the upper cover and
jacket for replacement, press a new bushing into the
upper end of the jacket tube with the recessed end of
the bushing toward the jacket tube. Use an arbor press
or the wood handle end of a hammer (Fig. 64). Push the
bushing down until it is 0.1 in. (2.5 mm) below the top of
the jacket tube. Use a pliers or punch to “crimp” the end
of the jacket tube over the bushing in two places ap-
proximately 90
o
away from the original crimped areas
(Fig. 65). Put clean multi-purpose grease on the inside
of the bushing.
