properly fit the flats on the input gear shaft to use the 1/4
inch drive, 0 to 15 inch lbs., Torque Driver.
12. When correct rotational torque has been ob-
tained, re- install clutch housing mount assembly (5A),
if removed, to recoiler assembly (5). Re- install this as-
sembly to transmission portion of the actuator.
-NOTE-
Flats on gear (6) shaft must line up with the brass
manual drive clutch (13) for proper assembly.
Pull manual drive cable slightly to position brass
clutch to align with flats on gear shaft (6).
13. Install new bolts (3) ADS 145- 10- 43 (2 each)
and (4) ADS 145- 10- 38 (2 each) and torque to 20- 25
inch pounds. Bolts are EATON P/N’s. Use Loctite grade
A (catalog number 88- 31) on bolt threads.
14. Reinstall cable support bracket and lock nuts (1)
on bolts (3 & 4). Torque lock nuts to 20- 25 inch pounds.
15. Install modification plate adjacent to I.D. plate (@
first 1000 hour replacement only). Mark first block on
modification plate with the figure “1” using metal stamp
or etching tool. Mark plate at each succeeding clutch
spring replacement with the next consecutive number.
16. Reinstall actuator into aircraft per procedures be-
low:
A. Install actuator into hat section lug.
B. Install Heim to retract bellcrank.
C. Route emergency cable through support brack-
et, pulleys to “T” handle position on floorboard. Insert
cable into “T” handle and tighten set screw.
D. Reconnect electrical connection. Check for
proper electrical and mechanical operation.
17. Verify rigging per Section 32-30-00.
-CAUTION-
Should be observed during installation for
proper placement of washers and bushings
on the retraction system.
18. Re- install aircraft belly panels.
32-30-06 - LANDING GEAR ACTUATOR, RECOIL-
ER SPRINGS/ CABLE AND DRUM ASSY RE-
PLACEMENT
1. Carefully separate pulley housing from recoiler as-
sembly (5) (Fig. 32- 16) by removing screws (14). Re-
tain pulley on shaft.
2. Slide pulley drum and cable off shaft.
3. Remove two (2) recoiler springs (5B), and two (2)
of three (3) spring spacers (5C) leaving third spacer in
housing. Be certain that spacer is in place before instal-
lation of two (2) new recoiler springs and previously re-
moved spacers.
4. Install new recoiler springs placing a spacer be-
tween each spring and over top spring.
IMPORTANT – Recheck proper installation of springs.
-NOTE-
When looking at recoiler assembly with shaft end
toward you, the spring tabs in the housing slot
should curve to the right as shown (Fig. 32- 16).
5. Inspect cable for sheathing damage. Replace
cable if sheathing is cut or stripped. Measure overall
cable length prior to reassembly. Cable length should
be 31 1/2” +/- 1/2” long.
6. Slide drum onto shaft and be certain that spring de-
tente on drum engages both recoiler springs by slightly
rocking drum end.
7. When full engagement is obtained, wrap cable
around drum in a clockwise direction- leaving 2” to 5” of
cablefreeofdrum.
8. Align slot in pulley housing with cable and slide
pulley housing over cable and drum assembly.
-NOTE-
Cable length in retract position may be adjusted
shorter or longer by holding clutch with the fin-
ger of one hand (to prevent shaft rotation), and
then with the other hand, rotating pulley housing
one (1) full turn CW (to shorten) or CCW (to
lengthen). Retention of clutch with finger will not
allow pretensioning of springs. Slight spring ten-
sion should be noted starting at 8” to 10”.
9. Holding housings together, pull properly aligned
cable several times to ensure the absence of binding
conditions. Measure cable length from side of housing.
At full extend, the length of cable should be 29” mini-
mum. In retracted position, cable length should be 5” to
8” long.
10. Bronze clutch (13) should be inspected for dam-
age or wear at slot where gear assembly engages dur-
ing manual extension of the landing gear.
11. If damaged or worn, remove pin (11) from disen-
gage arm (12) and slide disengage arm out so bronze
clutch (13) can be pulled from its driveshaft.
12. Replace bronze clutch and reassemble disen-
gage arm into recoiler assembly.
13. Attach clutch recoiler assembly to actuator gear
housing with the four (4) screws (3 & 4, Fig. 32- 16) re-
moved in 32- 30- 05.
32-30-07 - MANUAL EMERGENCY GEAR EXTEN-
SION SYSTEM
The manual emergency gear extension system is used
to extend gear only. The controls are in the floorboard
aft and between the front seats. To manually extend
gear:
1. Landing gear actuator C/B – PULL.
2. Move landing gear control switch to DOWN posi-
tion.
3. Push latch on manual extension control forward
with right thumb.
