One Piece Stator Assembly
A disassembled rotor stator and vanes that cannot be readily
assembled by hand can be assembled using the following pro-
cedures:
1. Place stator on wear plate (9) with seal ring (4) side
down, after following assembly procedures 1 through
13. Be sure seal ring is in place.
2. If assembly alignment studs are not used, align stator
bolt holes with wear plate and housing bolt holes. Turn
two bolts (1) finger tight in bolt holes approximately 180
degrees apart to retain stator and wear plate stationary.
3. Assemble rotor, counterbore down if applicable, into
stator, and onto wear plate (9) with rotor splines into
mesh with drive link (10) splines.
4. Assemble six vanes, or as many vanes that readily
assemble in stator vane pockets.
EXCESSIVE FORCE USED TO PUSH ROTOR VANES IN PLACE COULD SHEAR OFF
COATING APPLIED TO STATOR VANE POCKETS.
5. Grasp output end of coupling shaft (12) with locking pli-
ers or other appropriate turning device and rotate cou-
pling shaft, drive link, and rotor to seat rotor and
assembled vanes into stator, creating the necessary
clearance to assemble the seventh or full complement
of seven vanes. Assemble the seven vanes using mini-
mum force.
Remove two bolts (1) if used to retain stator and wear plate.
