DISASSEMBLY
General Instructions
1. Do not disassemble the motor any further than neces-
sary to replace or repair damaged parts.
2. Do not disassemble the motor unless you have a com-
plete set of new gaskets and o--rings for replacement.
3. When grasping a tool in a vise, always use leather--
covered or copper--covered vise jaws to protect the
surface of the part or motor and help prevent distor-
tion. This is particularly true of threaded members
and housings.
4. Do not remove any part which is a press fit in or on a
subassembly unless the removal of that part is neces-
sary for repairs or replacement.
Disassembly of the Motor
1. Clamp a large adjustable wrench in vise jaws with the
adjustable opening upward.
2. Adjust the jaw of the wrench to clear the body of the
Gear Case (14).
3. Roll the motor in the wrench jaw until it stops against
the Gear Case Grease Screw (15) and, using a wrench
on the flats of the Coupling Nut (33) at the flange end
of the Gear Case, loosen the Coupling Nut.
4. Roll the motor in the opposite direction until it stops
against the Gear Case Grease Screw and, using a
wrench on the flats of the Coupling Nut at the flange
end of the Gear Case, loosen the Coupling Nut.
5. Holding the motor horizontally over a workbench,
unscrew the Coupling Nut at the motor end of the
Gear Case and pull the motor from the Gear Case.
Do not lose the Flange Key (42).
6.
For Models with Square Drive Adapter (27A),
using a hex wrench, unscrew and remove the two
Adapter Screws (27B).
7. Unscrew the Coupling Nut and pull the Flange As-
sembly and the Spindle (27) out the of Gear Case.
Once the Spindle is removed from the Gear Case, the
entire gear train must be disassembled to install the
Spindle Planet Gears (28) or the Spindle Planet Gear
Assemblies (30) on the opposite end of the Spindle.
Do not lose the Flange Key.
8.
For Models with Square Drive Adapters,
carefully
grasp the Spindle in copper--covered vise jaws and
using a wrench on the square drive, unscrew and re-
move the Adapter.
9. Push the Spindle out the gear end of the Flange As-
sembly.
10. Remove the Spindle Seal (41) and Flange Seal (40)
from the inside of the Flange (39).
11. Using snap ring pliers, remove the Spindle Retaining
Ring (37) and pull the two Spindle Bearings (35) and
the Spindle Bearing Spacer (36) from the shaft of the
Spindle. Remove the second Spindle Retaining Ring.
