11. Assemble wear plate (9) over drive link (10) and
alignment 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
reassembled, go to One Piece Stator Assembly,
page 3-88 or Two Piece Stator Assembly, page 3-89.
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
manifold (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 counterbore 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 a new seal ring (4) and
assemble it 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 circum-
ference or circle around inside diameter. Polished
impression left on manifold by rotor set is another
indication of which surface must contact rotor set.
