-NOTE-
Check nose gear leg assembly for towing dam-
age. Replace if any dent exceeds 1/32 inch.
Twin limiter pads and adjustable stops (7) (Fig. 32- 23)
are installed on the nose gear leg assembly (A) to pre-
vent towing/turning damage to the leg assembly.
1. Every 100 hours remove cotter pin (1) (Fig. 32- 23)
and retorque nut (2) to 270- 300 inch lbs. Check holes
in leg assembly where pivot bolt (3) is located for any
wear. If holes are worn, replace leg assembly.
-CAUTION-
Bolt (10), washers and nut (9) (Fig. 32- 23) must
be installed as shown, from rear to front.
2. Rod end bearing (4) (Fig. 32- 23) should be in-
spected at least every 100 hours for any damage or
bending.

3. Check the steering horn assembly (5) collars and
spacers for looseness. Replace any bushings or
spacers that are worn. Shim steering horn as follows;
Run nose gear through full left travel and hold, measure
gap between 720095-15 arm assy and 720095-17
shaft assembly, record measurement. Check for full left
travel between rudder and nose gear assembly.
720095-15 arm should not contact 720095-17 shaft in
full left travel. It is cause for rejection if binding occurs.
Next; Run nose gear assembly through full right travel
and hold; measure gap between 720095-15 arm and
720020-501 collar and record measurement. Check for
full right travel between rudder and nose gear assem-
bly. it is cause for rejection if binding occurs. A gap of
.003 to .020 is acceptable as is on either side of
720095- 15 arm assembly. If gap is greater than .020
on either side of 720095-15 arm; shim as required with
720013-(x) shims to maintain .003 to .020 gap.

permissible) (Fig. 32- 24) when rudder is at its extreme
left and right travel position.
32-50-02 - NOSE GEAR STEERING AND TRACK-
ING
1. Level aircraft as described in Chapter 8.
2. Center nose wheel.
3. Place plumb line over and forward of nose gear
trunnion (see Fig. 32- 25).
4. Measure forward from aft edge of plumb line to
axle center line, assembled axle center- line to fall on
station - 13.375” +/- .25”.
5. Add spacer(s) under collar to reposition the axle if
required. Refer to IPC for parts number breakdown.
-NOTE-
Some collars have holes drilled off center and
may be turned over to change axle position.
6. Run gear through retraction/extension cycle.
Check nose gear door and wheel well tire clearances.
Re- rig if required.
