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
Torqmotor™ 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
finger 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
applicable, 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
components 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
pockets.
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
necessary 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 flat 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.
