22. Torque the two shuttle valve plug assemblies (21) in
end cover assembly to 9-12 ft. lbs. (12-16 N m) if
cover is so equipped.
Torque the two relief valve plug assemblies (21) in
end cover assembly to 45-55 ft. lbs.(61-75 N m) if
cover is so equipped.
One Piece Stator Construction
A disassembled rotor (8A) stator (8B) and vanes (8C) that
cannot 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
procedures 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 sta-
tor and wear plate stationary.
3. Assemble the rotor (8A), counterbore down if appli-
cable, 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
readily assemble into the stator vane pockets.
EXCESSIVE FORCE USED TO PUSH THE ROTOR VANES INTO
PLACE COULD SHEAR OFF THE COATING APPLIED TO THE STA-
TOR VANE POCKETS.
