Two Piece Stator Construction
A disassembled rotor set (8) that cannot be readily assembled by hand and has a two piece stator can be
assembled by the following procedures.
Assemble
stator halves
1. Place stator half (8B) onto wear plate (9) with
seal ring (4) side down, after following Torqmo-
tor™ assembly procedures 1 through 13. Be
sure the seal ring is in place.
Insert two
alignment
studs
2. Align stator bolt holes with wear plate and
housing bolts and turn two alignment studs
fi nger tight into bolt holes approximately 180
degrees apart to retain stator half and wear
plate stationary.
Assemble rotor
NOTE
3. Assemble rotor (8A), counterbore down if appli-
cable, into stator half (8B), and onto wear plate
(9) with rotor splines into mesh with drive link
(10) splines.
NOTE: Use any marking you applied to rotor
set components to reassemble the compo-
nents in their original relationship to ensure
ultimate wear life and performance.
Assemble vanes
CAUTION
4. Assemble six vanes (8C), or as many vanes that
will readily assemble into the stator vane pock-
ets.
CAUTION: Excessive force used to push the
rotor vanes into place could shear off the
coating applied to the stator vane pockets.
Assemble full
complement
of vanes
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 (8B), creating the neces-
sary clearance to assemble the seventh or full
complement of seven vanes. Assemble the
seven vanes using
minimum force.
Assemble seal
ring in stator
half
6. Place second stator half (8D) 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.
