3. Hold the Arbor in leather–covered or copper–covered
vise jaws. Insert the Rotor Key (30) into the slot of the
Rotor (31). The Rotor has a staked keyway on one end.
Place that end up, over the Arbor. Apply a light film of
the recommended oil to each Vane (32) and insert one
Vane, straight edge out, into each slot in the Rotor. If
any new Vanes are required, replace the entire set.
4. Place the Cylinder over the Rotor aligning the
Cylinder Dowel hole with the alignment hole in the
Front End Plate (29), and with the kidney port to the
right of the dowel hole.
5. Apply the Rear End Plate (35) with the kidney port to
the right of the dowel hole.
Take all measurements 30 degrees to the left of the
dowel hole when facing the hub side of the Seal.
Install the Rotor Bearing Seal hub down.
If the Controller Assembly (37) needs to be
replaced, you must also replace the Rotor Bearing
Seal Assembly (38) which consists of a rear rotor
bearing and a rotor bearing seal. If either the rear
rotor bearing or rotor bearing seal needs to be
replaced, BOTH must be replaced with a new
bearing and seal. DO NOT MIX OLD AND NEW
PARTS.
6. Check the outside diameter and large inside diameter
of the Rotor Bearing Seal (38) for wear. If the outside
diameter is worn to 1.176" (29.88 mm) or smaller,
and/or the large inside diameter is worn to 0.910"
(23.12 mm) or larger, install a new Rotor Bearing Seal.
7. Align the Rear End Plate (35), cavity and pin up, with
the larger hole in the Rotor Bearing Seal.
8. Press the Rear Rotor Bearing Seal Assembly onto the
hub of the Controller.
Use only the special 88V60–950 Controller Wrench
for installing the Controller Assembly.
