5-39. STEERING GEAR-Continued
Remove and discard the worm shaft seal ring (54). Then remove and discard the worm shaft O"
ring (55) from the worm shaft/input shaft (1).
During step (39) you should wear eye protection, as the spring
and loaded poppets could eject, and cause eye injury.
It is not usually required to service the poppet assembly. If required, however, position the rack
jaws. Then, remove two retaining rings (56), two poppet seats (57), two poppets (58), nylon spacer
rod (59), and spring (60).
If the bearing is cocked while you press it out, it will burnish the
bore, causing it to become oversized. You will then have to
replace the gear housing.
The housing bearing assembly (16) or race should only be removed if you determine that the
bearing must be replaced after following cleaning and inspection procedures. Remove the bearing
in the following manner: Use bearing mandrel to apply pressure from the side cover opening and
press the bearing out through the trunnion cover opening. Maintain a good, square contact
between the housing and press base to avoid damaging the housing bearing bore. Remove
retaining ring (61) from bearing. Discard bearing.
Remove bleed screw (62).
Cleaning and Inspection.
Dry cleaning solvent P-D-680 is potentially dangerous. Avoid
repeated and prolonged breathing of vapors and skin contact
with the liquid. Do not use near open flame, arcing equipment
or other ignition sources. Always wear eye protection and
protective clothing. The flash point of P-D-680 is 100 to 138
deg. F (38 to 59 deg. C).
(1) Clean all parts in dry cleaning solvent (Item 3, Appendix E).
Death or serious injury could occur if compressed air is directed
against the skin. Do not use compressed air for cleaning or
drying unless the pressure is/has been reduced to 30 psi (2.11
kg/cm2) or less. When working with compressed air, always use
chip guards, eye protection, and other personal protective
(2) Dry all parts with compressed air.
