One Piece Stator Construction
A disassembled rotor (8A) stator (8B) and vanes (8C) that cannot be readily assembled by hand can be assem-
bled by the following procedures.
Assemble stator
1. Place stator (8B) onto wear plate (9) with
seal ring (4) side down, after following
Torqmotor™ assembly procedures 1
through 13. Be sure the seal ring is in place.
SEE FIGURE 62.
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) finger tight into bolt holes
approximately 180 degrees apart to retain
stator and wear plate stationary.
Assemble rotor
3. Assemble the rotor (8A), counterbore down
if applicable, into stator (8B), and onto wear
plate (9) with rotor splines into mesh with
drive link (10) splines. SEE FIGURE 63.
NOTE
NOTE: If the manifold side of the
rotor was etched during Torqmotor
disassembly, this side should be up. If
the rotor is not etched and does not have
a counterbore, 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 (8C), or as many vanes
that will readily assemble into the stator
vane pockets. SEE FIGURE 64.
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
(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
(8B), creating the necessary clearance to
assemble the seventh or full complement
of seven vanes. Assemble the seven vanes
using minimum force. SEE FIGURE 65.
6. Remove the two assembled bolts (1) if used
to retain stator and wear plate.
Go to Torqmotor™ assembly procedure
#15, to continue Torqmotor™ assembly.
