11. Assemble wear plate (9) over drive link (10) and align-
ment studs onto housing (18).
12. Apply a small amount of clean grease to a new seal ring
(4) and assemble it into seal ring groove on wear plate
side of rotor set stator.
NOTE:
If rotor set is disassembled and cannot be easily reassem-
bled, go to One Piece Stator Assembly, page 3-59 or Two
Piece Stator Assembly, page 3-60.
13. Place assembled rotor set (8) on wear plate (9) with rotor
counterbore and seal ring side down and splines into
mesh with drive link splines.
NOTE:
It may be necessary to turn one alignment stud out of
housing (18) temporarily to assemble rotor set (8) or mani-
fold (7) over drive link.
NOTE:
Rotor set rotor counterbore side must be down against
wear plate for drive link clearance and to maintain original
rotor-drive link spline contact. A rotor set without a coun-
terbore that was not etched before disassembly can be
reinstalled using drive link spline pattern on rotor splines if
apparent, to determine which side was down. Rotor set
seal ring groove faces toward wear plate (9).
14. Apply clean grease to new seal ring (4). Install in seal
ring groove in rotor set contact side of manifold (7).
NOTE:
Manifold (7) is made of several permanently bonded
plates. Manifold surface that contacts rotor set has a series
of irregular shaped cavities on largest circumference or cir-
cle around inside diameter. Polished impression left on
manifold by rotor set is another indication of which surface
must contact rotor set.
