One Piece Stator Construction
A disassembled rotor (7) stator and vanes that cannot be readily assembled by hand can be assembled by the
following procedures.
Assemble stator
1. Place stator (7) onto wear plate (8) with seal
ring (3) side up, after following
Torqmotor™ assembly procedures 1
through 11. Be sure the seal ring is in place.
SEE FIGURE 58.
Insert
two bolts
2. If assembly alignment studs are not being
utilized, align stator bolt holes with wear
plate and housing bolt holes and turn two
bolts (1, 1A, 1B or 1C) finger tight into bolt
holes approximately 180 degrees apart to
retain stator and wear plate stationary.
Assemble rotor
3. Assemble the rotor (7), counterbore down if
applicable, into stator, and onto wear plate
(8) with rotor splines into mesh with drive
link (9) splines. SEE FIGURE 59.
NOTE
NOTE: If the manifold side of the rotor
was etched during Torqmotor disassem-
bly, this side should be up. If the rotor is
not etched and does not have a coun-
terbore, use the drive link spline contact
pattern apparent on the rotor splines to
determine the rotor side that must be
against the wear plate.
Assemble vanes
CAUTION
Assemble full
complement
of vanes
Remove two
assembled bolts
4. Assemble six vanes, or as many vanes that
will readily assemble into the stator vane
pockets. SEE FIGURE 60.
CAUTION: Excessive force used to push
the rotor vanes into place could shear
off the coating applied to the stator vane
pockets.
5. Grasp the output end of coupling shaft
(10) 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, creating
the necessary clearance to assemble the
seventh or full complement of seven vanes.
Assemble the seven vanes using minimum
force.
6. Remove the two assembled bolts (1, 1A,
1B or 1C) if used to retain stator and wear
plate.
Go to Torqmotor™ assembly procedure
#13, to continue Torqmotor™ assembly.
