10-3. STEERING KNUCKLE MAINTENANCE (Contd)
d. Adjustments
NOTE
Right and left steering knuckle adjustment is the same. This
procedure covers left steering knuckle.
Use a cold chisel to break loose tack weld (TM 9-237) between
nut and axle housing if old screw is present and adjustment is
needed.
1.
If steering stop screw (8) is replaced or needs adjustment, proceed as follows:
a. Aline the centerline (4) of steering arm (3) and axle housing (5) and place reference edge (1)
of protractor on same centerlines. Protractor center index is on grease fitting (2).
b.
Scribe reference line (6) on steering knuckle arm (7). Record protractor angle reading of
reference line (6).
Add 28 to 28-1/2 to angle reading recorded above. Turn steering knuckle arm (7) so that
c.
reference line (6) alines with new angle on protractor. Turn steering stop screw (8) in if
necessary.
Turn steering stop screw (8) until head of steering stop screw (8) contacts axle housing (5).
d.
Hold steering stop screw (8) to prevent turning and tighten nut (9) 94-120 lb-ft (127-163 Nm).
e.
f. Tack weld steering stop screw (8) to nut (9) and nut (9) to steering knuckle arm (7).
2. Measure and adjust steering knuckle end play as follows:
a. Install dial indicator gage with magnetic stand on axle housing (5) so that measuring
pointer (10) is on steering arm (3) and will measure vertical movement of steering knuckle (12).
b. With steering knuckle (12) unsupported by lever (13), set dial indicator gage to zero. If
nonzeroing gage is used, record reading of dial indicator gage.
NOTE
Jack stand may be used as fulcrum.
Position lever (13) and fulcrum (11) under steering knuckle (12).
c.
Push down on outer end of lever (13) and lift steering knuckle (12) until vertical motion of
d.
steering knuckle (12) ends. Record reading on dial indicator gage.
If reading is 0.004-0.014 in. (0. 10-0.36 mm), go back to task c., steps 18 and 19. If reading is
e.
more or less, go to steps f. and g.
