hole in output gear (39). If pin does not drop into
hole, tighten or loosen spacer nut until hole is aligned
and one pin drops into hole. (Note: spacer nut should
not be rotated more than 221/2 before pin drops into
hole in gear.) It is preferable to tighten spacer nut
down instead of loosening.
25. Remove pin from aligned hole. Install half dog set
screw (68) and tighten half dog point into hole i
output gear (39). Remove remaining pin and proceed
with assembly. Note: One hole must be in alignment
to have proper assembly.
26. Lightly grease O.D. of translating tube (66) with
Duboise M.P.G. grease (no substitutes) and
assemble outer tube (55) assembly over translating
tube (66) and thread into housing (42) (a sealing
compound such as Non-Hardening Permatex 2
should be used on threads).
27. Insert intermediate pinion shaft (32) in housing
(42) and place thrust washer (31) over shaft (32).
Assemble intermediate cluster gear (33) on shaft and
place thrust washer (31) on top.
28. Assemble bearing (28) on input pinion (29) (press on
inner bearing ring to prevent damage to bearing).
9. Pack housing (42) gear box cavity with Aeroshell #6
grease (no substitutes).
30. Assembly of Motor (53) to Housing (42)
a. Note location of flat on input pinion (29) by
marking spot on the coupling (47) posts. See
Figure 6-1B on page 14.
b. Insert grommet (50) on input pinion (29) between
coupling (47) posts and install “O”-Ring (52) in
cavity of insert (51).
c. Pack cavity with Aeroshell #6 grease.
d. If hole plug (54) is in rear end of motor, remove.
e. Feed motor (53) lead wires through hole in
housing (42) lining up couplings (47) on input
pinion (29) and motor (53) shaft. (See Figure
6-1B on page 14.) Motor screws should be lined
up with tapped holes in housing (42).
NOTE
Alignment is critical at this point. See Figure 6.1B on
page 14. Note that input pinion (29) and motor (53)
shaft flats are opposite each other.
f. Assemble motor (53) into housing and install
screws (care should be taken during assembly
that end bells do not separate from motor (53)
shell).
g. With a screwdriver turn motor shaft by inserting
in motor shaft slot in end of motor. If couplings
are properly installed, the shaft will turn freely in
both directions. If motor shaft will not turn, this
is an indication that a couplings are not properly
installed.
31. Insert intermediate pinion shaft (32) in housing
(42) and place thrust washer (31) over shaft (30).
Assemble intermediate cluster gear (33) on shaft and
place thrust washer (31) on top.
32. Assemble bearing (28) on input pinion (29) (press on
inner bearing ring to prevent damage to bearing).
33. Pack housing (42) gear box cavity with Aeroshell #6
grease (no substitutes).
34. Insert dowel pins (27) in housing (42) and place
gasket (41) in place over dowel pins (27).
35. Install air vent (58) in outer tube (55) ( it may be
necessary to back outer tube out in order to install air
vent or to have vent in a more desireable position).
Spot drill tube and install set screw (38) to hold tube
in place.
36. Install spring (61) into end of screw (62).
NOTE
If unit has potentiometer assembly (26) and gear
(26b) does not have to be replaced or if unit has no
potentiometer feature, proceed to Step 35.
37. Potentiometer Assembly (26)
a. If nut and washer were removed from
potentiometer, assemble washer (26d) and nut
(26c) on potentiometer (26a). Nut (26c) should
not be tightened on potentiometer (26a) face.
b. Assemble gear (26b) on potentiometer (26a
shaft.
NOTE
Gear should be assembled with a very light press. See
sketch for required dimension of gear on potentiometer.
Take care not to damage potentiometer.
