3. Install assembled rotor housing (024) in case (001), aligning housing (024) to receive stop pin (006).
Install stop pin (006) with Dyna seal (007) in case (001).
4.
(Figures 3, 7, 8, 9 and 11)
Install O-ring (028) in groove of balance piston housing (022 or 045), and
install balance piston housing (022 or 045) in case (001), ensuring that bore of balance piston housing
(022 or 045) engages oil balance tube (026 or 036) installed in rotor housing (024).
5.
(Figures 3, 7, 8, 9)
Install gasket (009) on case (001).
6. Install inboard cover (046
or
008) on case (001) using capscrews (004 or 093). Tighten capscrews (004
or 093) to proper torque value listed in Table 2.
NOTE:
If applicable, lockwashers (092) will be installed with bolts (004).

8. Assemble power rotor (044 or 063) as follows:
(Figures 7, 8, 9)
Install sleeve (038) on power rotor (044 or 063) shaft next to piston.
(Figures 3, 7, 8, 9)
Install mechanical seal (025) rotating assembly on power rotor (044 or 063) shaft.
Tighten set screw if applicable.
NOTE:
Refer to Figure 2 for Mechanical Seal Types for proper assembly.
(Figures 6, 10 and 11)
If seal is a J seat design Install stationary seat on power rotor (063 or 044) shaft.
Then install spacer (014 or 048). If seal stationary seat is an O-ring design, be sure O-ring is installed
on seal seat and then install seat in seal seat adapter (048 or 014). Be sure groove in back of stationary
seat mates with pin in seal seat adapter (48 or 14)
NOTE:
Refer to Figure 2 for Mechanical Seal Types for proper assembly
(Figures 3, 7, 8, 9)
Install inner truarc ring (042) in groove of power rotor. Press ball bearing (049) on
power rotor (063) shaft, pressing only on inner race of bearing. Install outer truarc ring (042) in groove
of power rotor shaft.
9.
(Figures 3, 7, 8, 9)
Install gasket or O-ring, based on mechanical seal design, in mechanical seal bore
of inboard cover (046 or 008).
10. Install assembled power rotor (044 or 063) in inboard cover (046 or 008), centering each part as it
enters pump case (001).
