NOTE
Make note of drain holes in the rotor blade slots. These holes will be on the leading edges in
relation to rotation when rotor is reinstalled. Mark or tag as needed for assembly reference.
Rotation is always toward the side of the stator where oil filter and bypass are mounted.
(15)
Remove the eight blades (35).
CAUTION
Rotor/shaft assembly weighs approximately 60 lbs (27.2 kg). Remove it carefully.
(16)
Carefully slide the rotor/shaft assembly (36 thru 43) out of the stator (51).
CAUTION
Excessive heat can cause softening of metal. If a bearing inner race must be heated for
removal, discard it and replace the entire bearing.
(17)
When it is necessary to disassemble the rotor, use a gear puller to remove the inner race of bearing (22),
and nonintake end cover (40) from end of rotor shaft (36). If the inner race cannot be removed with a gear
puller, heat the race evenly with a torch and pull race off shaft as quickly as possible to avoid over heating.
(18)
Remove rotor (37), key (38), bearing (39), and shaft (36) as an assembly. Removal of male connector (41)
drive screw (42) and data plate (43) is not necessary unless they are to be replaced.
(19)
Steel ball (44), preformed packing (45) and eye bolt (46) can be removed if replacement is necessary. If
removed, discard preformed packing.
(20)
Remove two each drain valve plugs (47), preformed packings (48), springs (49), and drain valves (50)
from stator (51). Discard preformed packings.
b.
Cleaning.
(1)
Check parts for excessive buildup of dirt and debris. Clean if needed.
WARNING
Dry cleaning solvent used to clean parts is potentially dangerous to personnel and property.
Do not use near open flame or excessive heat. Use in well ventilated area.
NOTE
Prior to reassembly, clean all metal parts. They must be free from oil, grease and corrosion
resistant compounds on all interior and exterior surfaces.
(2)
Wash all metal parts with dry cleaning solvent (item 11, section II, appendix E).
(3)
Dry thoroughly with clean, cloth (item 2, section II, appendix E).
