SECTION 3 - CHASSIS & TURNTABLE
11. Assemble wear plate (9) over the drive link (10) and
alignment studs onto the housing (18).
12. Apply a small amount of clean grease to a new seal ring
(4) and assemble it into the seal ring groove on the wear
plate side of the rotor set stator.
13. Install the assembled rotor set (8) onto wear plate (9)
with rotor counterbore and seal ring side down and the
splines into mesh with the drive link splines.

NOTE: It may be necessary to turn one alignment stud out of the
housing (18) temporarily to assemble rotor set (8) or mani-
fold (7) over the drive link.
NOTE: If necessary, go to the appropriate, "Rotor Set Component
Assembly Procedure. "
NOTE: The rotor set rotor counterbore side must be down against
wear plate for drive link clearance and to maintain the
original rotor-drive link spline contact. A rotor set without
a counterbore and that was not etched before disassembly
can be reinstalled using the drive link spline pattern on the
rotor splines if apparent, to determine which side was
down. The rotor set seal ring groove faces toward the wear
plate (9).
14. Apply clean grease to a new seal ring (4) and assemble it
in the seal ring groove in the rotor set contact side of
manifold (7).
NOTE: The manifold (7) is made up of several plates bonded
together permanently to form an integral component. The
manifold surface that must contact the rotor set has it's
series of irregular shaped cavities on the largest circumfer-
ence or circle around the inside diameter. The polished
impression left on the manifold by the rotor set is another
indication of which surface must contact the rotor set.
