gland (67) and rotate CCW (viewed from
above) to removal of the manual handwheel
operator sub-assembly (MHWO).
6. Place the sub-assembly (MHWO) into a vise,
grasping with leaded jaws on the coarse-
screwed handwheel stem (58.2) near the
base of the handwheel (58.1), oriented to
allow driving-out the rolled pin (66) securing
the handwheel (58.1) to the handwheel stem
(58.2).
7. Drive pin (66) out using a suitable punch and
locking pliers. Set pin (66) aside for reuse.
Remove handwheel (58.1) from stem (58.2).
8. Rotate locking lever (59) CCW (viewed from
handwheel-end) to removal.
9. Slide washer (60) and threadseal washer
(61) off handwheel stem-end (58.2). Discard
threadseal washer (61).
10. Remove remaining engaged parts (67) (58.2)
from vise. Reorient horizontally in vise along
fl ats of handwheel gland (67).
11. Place stick punch in drive-pin hole and rotate
handwheel stem (58.2) CW (viewed from hand-
wheel (58.1) end) back into the handwheel
gland (67). When stem (58.2) protrudes far
enough through gland (67), re lo cate locking
pliers to opposite end and ro tate stem (58.2)
until stem (58.2) fully dis en gag es.
12. Remove O-ring (62) from handwheel gland
(67).
13. Remove O-ring (63) from handwheel stem
(58.2).
14. Place parts (58.2) (59) (60) (64) (67) into a
suitable solvent and clean as much as pos-
si ble, remove parts and allow to dry.
15. Inspect handwheel stem (58.2) with em bed ded
ball (64) for wear on ball (64). If ball (64) is
worn, or threads of stem (58.2) are dam aged,
replace handwheel sub-assembly (58); i.e.
parts (58.1) (58.2) and (64).
16. If handwheel gland (67) shows signs of wear
in female threads (i.e. loose gauging), replace
handwheel gland (67) and self-tapping slot-
ted-head screw (65). NOTE: A re place ment
handwheel gland (67) will require drilling a
new 5/32" x 1-1/16" (4mm x 25.5mm) deep
hole into the lip of the upper casing (1).
17. Install new O-ring (63) onto handwheel stem
(58.2) and new O-ring (62) onto handwheel
gland (67).
18. Place a thin coat of lithium grease on the
handwheel stem O-ring (63) and the im me di-
ate surrounding area of the handwheel stem
(58.2).
19. Engage the handwheel stem (58.2) into the
gland’s (67) underneath side. When the hand-
wheel (58.1) end of the stem (58.2) pro trudes
through the gland’s (67) upper side, place a
new threadseal washer (61) over the stem’s
(58.2) upper end. Continue engaging stem
(58.2) until the O-ring (63) is pulled into the
gland (67).
20. Install washer (60) and locking lever (59) onto
stem (58.2).
21. Place handwheel stem (58.2) into a soft-jawed
vise. Position handwheel (58.1) onto stem
(58.2) with holes for pin (66) aligned. Insert
pin (66) and drive through stem (58.2) and
handwheel (58.1) far side. Remove handwheel
assembly (MHWO) from vise.
22. Place heavy duty wheel bearing grease as
specifi ed previously onto the stem-end ball
(64). Engage the gland (67) into the upper
casing (1) female opening. Align tapped open-
ing for self-tapping slotted-head screw (65).
23. Install slotted-head screw (65) fully.
G. Adjusting Screw Assembly and Actuator Plug
Maintenance:
1. Reference Item Number drawing at end of the
IOM.
2. Determine the portion of the text of Sub sec-
tion F. above that would apply to the adjust-
ing screw assembly (ASA) counterpart of
the manual handwheel operator (MHWO)
as sem bly, and complete maintenance in a
sim i lar procedure. NOTE: Adjusting screw
assembly (ASA) is ONLY applied to reverse-
action, ATO-FC Ranger QCT units (AA) (BA).
3. Determine the portions of the text of Sub-
sec tion F. previous that would apply to the
ac tu a tor plug (67) coun ter part of the manual
handwheel operator (MHWO) as sem bly, and
complete maintenance in a similar procedure.
NOTE: Actuator plug (67) may be applied on
all Premier units (AA) (BA) and ONLY direct-
action, ATC-FO Ranger QCT units (AA) (BA).
H. Replacement of Range Springs:
