One Piece Stator Construction
A disassembled rotor (8A) stator (8B) and vanes (8C) that can-
not be readily assembled by hand can be assembled by the
following procedures.
1. Place stator (8B) onto wear plate (9) with seal ring (4)
side down, after following Torqlink™ assembly proce-
dures 1 through 13. Be sure the seal ring is in place.
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.
3. Assemble the rotor (8A), counterbore down if applica-
ble, into stator (8B), and onto wear plate (9) with rotor
splines into mesh with drive link (10) splines.
NOTE: If the manifold side of the rotor was etched during Torqlink
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.
4. Assemble six vanes (8C), 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 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.
6. Remove the two assembled bolts (1) if used to retain sta-
tor and wear plate.
