4. Assemble six vanes, or as many vanes that will read-
ily assemble into the stator vane pockets.
EXCESSIVE FORCE USED TO PUSH THE ROTOR VANES INTO
PLACE COULD SHEAR OFF THE COATING APPLIED TO THE STA-
TOR VANE POCKETS.
5. Grasp the output end of coupling shaft (12) with
locking pliers or other appropriate turning device
and rotate coupling shaft, drive link and rotor to seat
the rotor and the assembled vanes into stator, creat-
ing the necessary clearance to assemble the sev-
enth or full complement of seven vanes. Assemble
the seven vanes using minimum force.
6. Remove the two assembled bolts (1) if used to retain
stator and wear plate.
Go to assembly procedure #15, to continue assem-
bly.
Two Piece Stator Construction
A disassembled rotor set (8) that cannot be readily assem-
bled by hand and has a two piece stator can be assem-
bled by the following procedures.
1. Place stator half onto wear plate (9) with
seal ring (4) side down, after following motor assem-
bly procedures 1 through 13. Be sure the seal ring is
in place.
2. Align stator bolt holes with wear plate and
housing bolts and turn two alignment studs
finger tight into bolt holes approximately 180
degrees apart to retain stator half and wear plate
stationary.
3. Assemble rotor, counterbore down if applicable, into
stator half, and onto wear plate (9) with rotor splines
into mesh with drive link (10) splines.
NOTE: Use any marking you applied to rotor set compo-
nents to reassemble the components in their original
relationship to ensure ultimate wear life and perfor-
mance.
4. Assemble six vanes, or as many vanes that will read-
ily assemble into the stator vane pockets.
EXCESSIVE FORCE USED TO PUSH THE ROTOR VANES INTO
PLACE COULD SHEAR OFF THE COATING APPLIED TO THE STA-
TOR VANE POCKETS.
5. Grasp the output end of coupling shaft (12)
with locking pliers or other appropriate turning
device and rotate coupling shaft, drive link and rotor
to seat the rotor and the assembled vanes (8C) into
stator half, creating the necessary clearance to
assemble the seventh or full complement of seven
vanes. Assemble the seven vanes using minimum
force.
6. Place second stator half on a fl at surface with seal
ring groove up. Apply a small amount of grease to a
new seal ring (4) and assemble it into stator half ring
groove.
7. Assemble the second stator half over the two align-
ment studs and rotor with seal ring side down onto
the first stator half aligning any timing marks applied
for this purpose.
IF THE STATOR HALF (8B) IS A DIFFERENT HEIGHT (THICKNESS)
THAN STATOR HALF (8D) THE STATOR VANES (8C) OR (8E)OF
THE SAME LENGTH (HEIGHT) AS THE STATOR HALF MUST BE
REASSEMBLED IN THEIR RESPECTIVE STATOR HALF FOR THE
ROTOR SET TO FUNCTION PROPERLY.
