d. Insert pmIOn shaft (42) plain end first. into unthreaded end of gear
case and push through pinion as far as rear wall of gear case, forcing
out the dummy shaft.
e. Remove dummy shaft. and start pinion shaft into rear wall of case.
Do not drive pinion shaft all the way into gear case until all shafts
are inserted.
f. Assemble remaining long pinions in gear case.
g. Using dummy shaft, insert short bushings (47) into short pinion (46)
in same manner covered in paragraphs a and b above. With short
pinion, use pinion spacer (56).
h. Insert short pinion (46) into gear case, pinion toward front of case.
to line up with hole in inner row and insert pinion shaft (20) as
described in d above.
i. Assemble remaining short pinions in gear case.
2. Assemble case bushing (23) to gear case with edges of race in line with
flats on pinion shafts. Replace lockwashers (13) and capscrews (14).
3. Insert propeller gear (24) through rear of gear case in mesh with long
pinions.
4. Press case ball bearing (58) into gear case and onto propeller gear by
supporting entire assembly on propeller gear inside front end of gear
case. Make certain that case ball bearing is seated properly on propeller
gear and into gear case. Install case ball bearing retaining ring (59) in
groove in gear case next to case ball bearing.
5. Press clutch plate carrier (27) onto reverse gear tailshaft (2-1) or (2-2).
6. Align splines on reverse gear tailshaft and press tails haft through pro-
peller gear until propeller gear is seated against the clutch plate carrier
already on tailshaft. Support the entire assembly on propeller gear inside
front end of gear case during pressing operation.
7. Place Woodruff key (61) on end of tailshaft inside propeller gear.
8. Install clutch plates in clutch plate cavity in rear of gear case starting
first with bronze clutch plate (54) and alternating ·"eel plate (34) and
bronze clutch plate.
9. Install pressure plate (49) on top of last bronze clutch plate in clutch
plate cavity.
NOTE: Make certain that all plates ride freely and that no binding is apparent
during assembly.
10. Assemble finger assembly (52) ~o screw collar (53) using finger pins (51)
and securing with cotter pins.
11. Thread screw collar (53) onto gear case assembly (41) approximately half
of the thread length.
12. Place operating sleeve assembly (50) onto tailshaft. Position ball ends of
finger assembly over sleeve assembly.
13. Continue screwing screw collar onto gear case (41) until finger assembly
will snap over center and lock into position against the shoulder of the
pressure plate (49).
14. Push operating sleeve assembly (50) forward until finger assemblies are
free.
15. Place lockwasher over end of locks crew (55) and thread lockscrew into
one hole near edge of screw collar (53). Rotate screw collar until dog on
end of lockscrew lines up with closest hole in pressure plate.
16. On reduction tailshafts, install retaining ring on reverse gear tailshaft
making certain that retaining ring is seated properly in groove in reverse
gear tailshaft.
