4. Insert primary thrust plate (25) into rotor head,
flat side first. Thrust plate and rotor head surfaces must be
flush to assure proper assembly and operation of the pumps
(See fig. 4-6.)

4-39. Rotor Gear Joint and Conveyor Assembly
1. After lightly lubricating, position O-ring (24) onto outer
diameter slot of shaft adapter (23). With six socket head
screws (N), attach shaft adapter to gear joint shell (33), be-
ing careful that O-ring is maintained in its proper position.
Evenly tighten the six screws.
2. After lightly lubricating, position O-ring (22) into inside
diameter slot of shaft adapter (23). Position shaft adapter
(23) over end of drive shaft (4) so that the two pins
(C) in end of drive shaft fit into the non-tapped, counter-
bored holes of shaft adapter (23). Check that the O-ring is
properly seated. Thread four socket head screws (O)
through shaft adapter and into threaded holes in drive
shaft. Evenly tighten the four screws (O).
3. Place stator adapter (21) on suction end of stator
(44) with its flat side against stator. Place O-ring (20)
around the step in stator adapter.
4. Slide gear joint shell (36) on end of conveyor as-
sembly (35) with larger diameter opening facing out. 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.
5. Apply a small amount of lubricant to the flat face of
seal support (31), and slide it onto conveyor assembly so
that flat face of support is against seal (32).
6. Grease the concave spherical surface of rear thrust
plate (30), and position thrust plate against seal (32) with
lip on outside diameter of seal fitting the step on back side
of thrust plate.
7. Apply a film of grease to 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
assembly, and tighten against gear ball. Apply grease to
spherical surfaces and teeth of gear ball.
8. Apply grease to teeth of ring gear (27), and slide
ring gear onto the gear ball (29). When ring gear is in
place, keyways should be facing lock nut end of connect-
ing rod.
9. Apply a thin coating of grease to spherical surface
of thrust plate (25) already installed in rotor head. Fill the
recessed area in rotor head with grease.
10. Slide gear joint shell (36) over assembled gear joint
components, being careful to seat outside diameter of
gear joint seal (32) in end of gear joint shell (36). The two
tapped holes in gear joint shell should be in line with one
of the keyways in ring gear.
11. Place keys (26) in keyways in ring gear. Check to
insure the tapped holes in the side of gear joint shell are
aligned with one of the keyways.
12. Align the keys in ring gear with the keyways in rotor
head. Slide assembled gear joint shell onto rotor head,
checking to be sure the keys are properly engaged in rotor
head and ring gear. The shallow hole in rotor head should
ne aligned with the first threaded hole in outside of gear
joint shell. Thread set screw (Q) into threaded hole in shell
until light contact is made with the hole in rotor head.
13. Place O-ring (38) into step in gear joint shell. Align
holes in head ring (39) with six threaded holes in end of
gear joint shell, and install stainless socket head screws
(N). Tighten the six socket head screws evenly, checking
to insure O-ring (38) remains in place. When tightened
properly, a small gap of a few thousandths of an inch may
exist between shell (36) and head ring (39).
