14. Excess grease in the assembly will be purged from
the vent hole while the socket head screws are tightened.
Tighten set screw (Q) in shell. Move the free end of con-
veyor assembly in a circular motion to assure that the joint is
free and assembled properly. This will also help to purge
excess grease from the assembly.
15. Install stainless steel pipe plug (P) in the second hole
in the shell and tighten.
4-40. Drive End Gear Joint Assembly
1. On the other end of conveyor assembly (35), slide the
gear joint retainer (34), with flat side toward conveyor, until it
contacts the conveyor flight. After lightly lubricating, slide
O-ring (24) over slot in gear joint retainer (34). Fit a gear joint
seal (32) onto conveyor assembly (35). The seal must be
positioned so that flat face of seal neck fits into seal retainer
component of conveyor assembly. Apply a small coating of
approved gear joint lubricant to inside surfaces of seal.
2. Apply a small amount of lubricant to flat face of seal
support (31), and slide it onto conveyor assembly so that flat
face of support is against seal (32).
3. Grease the concave spherical surface of secondary
thrust plate (30), and position thrust plate against seal (32)
with the lip on outside diameter of seal fitting the step on
back side of thrust plate.
4. Apply a film of grease to the splines on inside of gear
ball (29). Install gear ball on conveyor assembly (35), with
counterbored end (end without splines) first on conveyor
assembly. Gear ball should slide freely against shoulder on
conveyor assembly. Place lock nut (28) on conveyor assem-
bly and tighten against gear ball. Apply grease to spherical
surfaces and teeth of gear ball.
5. Slide primary thrust plate (25) into gear joint shell (33),
with its flat side fitting into the recessed part of shaft adapter
(23). After lubricating, fit two keys (26) into the exposed
keyways in the shaft adapter (23). Liberally apply grease to
the teeth of ring gear (27). Insert ring gear (27) into gear joint
shell(33) with the keyway side inserted first. Align ring gear
so that the keyways are engaged with keys (26) that are in
shaft adapter (23).
6. Insert the gear ball assembly end of conveyor as-
sembly (35) into gear joint assembly until teeth of gear ball
and teeth of ring gear become meshed together. It may be
necessary to slightly turn drive shaft (4) until these teeth can
properly align to mesh together.
7. After the holes have been aligned, thread hex head
screws (T) and lockwashers thru stator clamp ring (40A),
stator adapter (21), and into threaded holes in suction hous-
ing (19). Evenly tighten the screws.
8. Slide gear joint retainer (34) into end of gear joint shell
(33), being careful that O-ring (24) remains in the slot, and
that gear joint seal (32) is properly seated in position. Rotate
gear joint retainer (34) until its holes become aligned with
threaded holes in end of gear joint shell (33). Thread six
socket head screws (N) into the holes and tighten evenly.
9. Insert stainless steel pipe plug (P) in threaded hole of
gear joint shell (33) and tighten.

4-41. Stator Support/Discharge Assembly
1. Place top of stator support(s) (41) over stator and fas-
ten to bottom half of stator supports using hex head screws
(R).
2. Place stators gasket (42) in recess in discharge flange
(45) and position discharge flange on end of stator. Align
holes in stator clamp ring (36B) with threaded holes in dis-
charge flange, and install and tighten hex head screws (S)
and lockwashers.
4-42. Final Assembly
1. Install inspection plates (17) to suction housing (19)
with gaskets (18), using hex head screws (L) and
Iockwashers.
2. Install pipe plugs (M and J) and zerk fittings (G) in ap-
propriate threaded holes in suction housing. Install pipe
plugs (M) in threaded holes in bearing housing, or attach
drain lines if preferred.
3. Connect power source. Turn on flush water to packing
if used. Open suction and discharge valves, and start pump.
4-43. Packing Adjustment
For packing adjustment, refer to Section 4-3.
4-44. ASSEMBLY OF G3 BRIDGE BREAKER
Note: In the following G3 assembly instructions, the part
reference numbers are from fig. 4-10.
G3 Bridge Breaker parts are assembled in reverse order of
dismantling. The following suggestions are offered:
Note: While unit is dismantled, check all gaskets and
O-rings, and repack bearings.
4-45. Suction Flange Installation
Note: It is necessary to properly position suction flange
to suction port of pump, and secure before final
assembly.
1. Place gasket (32) and suction flange (31) on suction
housing flange of pump.
2. Attach suction flange (31) to suction housing of pump
with desired hardware.
4-46. Packing Installation
1. Insert three rings of packing (23), lantern rings (24) and
three additional rings of packing (23) into both stuffing boxes
on each end of suction flange (31). All but one ring may fit
into stuffing boxes. As the unit operates, the packing will
compress and the last ring can be added.
4-47. Mounting Bearings
1. Install seals (26) into both holes in bearing retainer (28).
2. Insert bearings (27) into bearing retainer (28).
