Assemble a new seal ring (20), flat side up, into
commutator (19) and assemble commutator
over end of drive link (14) onto manifold (18)
with seal side up.
Assemble new seal (7) on housing (6), apply a
generous amount of SAE 10W40 to both ends
of sleeve (22)1 and assemble onto housing.
Make sure sleeve is sitting in a non-cocked
Turn a plug (25) with a new O-ring (26) if
required loosely onto one end of cover (23)
valve cavity if required.
Then insert a spring (27), the valve (28) and
another spring (27) into the other end of the
valve cavity. Turn another plug (25) with new
O-ring (26) loosely into cover valve cavity.
Assemble a new seal ring (7) onto end cover
and assemble end cover onto sleeve (22) in a
If the end cover has a valve (28) use
the line you previously scribed on
the housing (6) to radically align the
end cover port into its original
Assemble seven special bolts (24) and screw in
finger tight. Removal of the two alignment
studs should be made after at least two bolts
progressively tighten the bolts to pull end cover
assembly (23) and sleeve (22) into place with a
final torque of 50 ± 5 ft. lbs. (68 ± 8 N m).
The special bolt (24) required for use
with the shuttle valve (28) end cover
assembly (23) is longer than the bolt
required with the standard end cover
assembly. Refer to the individual
service parts list for correct service
Torque the two plug assemblies (25) in end
cover assembly to 12-19 ft. lbs. (16-26 N m).
If seal (5), washer (4), back-up washer (3), snap
ring (2) and seal (1) have not yet been
assembled, invert housing in vise so the
coupling shaft (11) is pointing up and follow
procedures #3 and #4 under "Replacement of
High Pressure Seal" on page 6 to assemble
The assembly of Torqmotor is now . complete except for
woodruff key (1A), nut (11B), washer (11C), bolt (11D)
or lock washer (11E) if applicable at Torqmotor
installation. See final checks.
ROTOR, STATOR, VANE ASSEMBLY PROCEDURE
A disassembled rotor (16A), stator (16C) and vanes
(16B) the cannot be readily assembled by hand can be
assembly by the following procedures.
Place stator (16C) onto wear plate (15) after
following Torqmotor assembly procedures 1
If assembly alignment studs are not being
utilized, alights stator bolt holes with wear plate
bolt holes and turn two bolts (24) finger tight into
bolt holes 180o apart to retain stator and wear
Assemble six vanes (1681 into the stator vane
Assemble rotor (16A), counterbore down, if
applicable, into stator (16CI and onto wear plate
(15) with rotor splines in mesh with drive link
Grasp the output end of coupling shaft Ill with
locking pliers or other appropriate turning
devices and Ttate coupling shaft, drive link and
rotor to seat the rotor and assembled vanes into
assemble seventh vane. Assemble the seven
vanes using minimum force.
Remove the two assembled bolts if used to
retain stator and wear plate.
