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 ring that is
located on the drive shaft hub in front of the ball bearing that
is supporting the drive shaft.
14. From the opposite side of the gear housing (clutch side) slide
the drive shaft assembly out of the gear housing.
15. Inspect the grease seal located inside the bore from which
the drive shaft was removed. Replace if worn or damaged.
