6. Locate the clutch armature assembly on the end of the
engine shaft. Note the two set screws as well as the
unused, threaded hole in the taper lock bushing at the
center of the clutch hub.
7. Using an 1/8" hex wrench, remove the two set screws from
the taper lock bushing
8. Thread one of the set screws into the unused, threaded
hole on the taper lock bushing. As the screw tightens,
the bushing will loosen. Once the bushing has loosened
enough, slide the clutch armature assembly off the engine
shaft.
9. Before replacing the clutch
hub and armature assembly
the proper "set back" must
be created. Using the hub
set-up tool (P/N 0555926),
create a "set back" of 0.10"
between the friction surface
of the clutch armature and the
forward face of the clutch hub.
NOTE: a new clutch hub and
armature assembly will
come pre-assembled, but
the "set back" may not be
correct. The "set back"
must still be created using
the hub set-up tool.
10. To replace the clutch armature assembly , line up the
three holes in the taper lock bushing with the three holes
in the clutch armature and insert the bushing into the
center of the clutch armature.
11. Line up the key on the taper lock bushing with the keyway
on the engine shaft and slide the assembly onto the shaft
with the holes facing out.
12. Apply blue Loctite to the two set screws and insert the
screws into the taper lock bushing. Tighten the set screws
only two turns at this time.
13. Using the clutch set-
up tool (P/N 0555926),
position the clutch
armature on the engine
shaft. Hold the tool
across the face of the
clutch housing so that the
center, recessed portion
of the tool straddles
the clutch armature
assembly. Pull the clutch
armature assembly
towards the tool until the
face of the armature is
against the tool.
14. While holding the clutch armature assembly against the
tool, use an 1/8" hex wrench and alternately tighten the set
screws into the taper lock bushing. Torque to 65–75 in/lbs.

15. Make sure the friction surface of the clutch armature is
clean and free from oil or grease.
Removing the clutch Rotor, clutch Field, and Drive
Shaft assembly
1. Follow steps 1–7 in "Removing/Replacing the Clutch
Armature Assembly."
2. Locate the clutch rotor assembly, which will be inside the
rear the gear housing. Note the locations of the three
socket screws and the two empty, threaded holes on the
clutch rotor.
3. Using a 3/16" hex wrench, remove the three socket screws
and lock washers that secure the clutch rotor to the drive
shaft assembly.
4. Thread two of the socket screws into the empty, threaded
holes and tighten alternately. This will push the clutch
rotor away from the drive shaft assembly and pinion.
5. Using a Phillips screwdriver, remove the four screws that
secure the heat sink assembly to the housing. Carefully
remove the heat sink assembly from the housing.
6. Locate the two clutch field wires that pass from the gear
housing into the control housing through a hole in the back
of the control housing. Remember the wire connection
terminals on the relay assembly (label if necessary) and
disconnect the wires. Gently move the heat sink assembly
away from the housing and rest it on the work surface by
the control housing.
7. Locate the four pairs of set screws that secure the clutch
field to the gear housing. They are located on the exterior
of the gear housing at the 12, 3, 6, and 9 o'clock positions
while facing the clutch field end of the gear housing.
Using an 1/8" hex wrench, remove the setscrews.
Remember the location of the two clutch field wires with
respect to the grommet and EPC housing.
8. Carefully slide the clutch field out of the gear housing,
keeping the field square to the gear housing so it does not
bind.

NOTE: To remove the drive shaft assembly, the pump
housing first must be removed from the gear
housing.
9. Using a Phillips screwdriver, remove the four front cover
screws. Remove the front cover.
10. Using a 1/4" hex wrench, remove the four socket screws
that secure the pump housing to the gear housing.
11. Slide the pump housing away from the gear housing.
12. Remove and clean the housing gasket. Replace if
damaged.
13. Locate the drive shaft pinion that is protruding from the
front side of the gear housing. Remove the small snap
