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. To remove the grease seal, use a flat blade
screwdriver to carefully pry the seal from the bore.
16. Clean the inside of the gear housing.

Installing the clutch Rotor assembly, clutch
Field and Drive Shaft assembly
1. If the drive shaft grease seal was removed, press a new
seal into the bore from which the old seal was removed.
2. From the clutch side of the gear housing, insert the drive
shaft assembly into the bore, through the grease seal, and
through the ball bearing on the gear side of the gear housing.
3. From the gear side of the gear housing, insert the snap
ring into the groove on the drive shaft hub in front of the
ball bearing.
4. Place the housing gasket over the gear housing dowel pins.
5. Carefully place the pump housing assembly in front of the
gear housing assembly, lining up the gear housing dowel
pins with their corresponding holes in the pump housing.
Slide the pump housing onto the gear housing until there
is no gap between the housings and gasket.
IMPORTaNT: Do not force the pump housing and gear
housing together.
6. Locate the four socket screws and lock washers that
secure the pump housing to the gear housing.
7. Using a 1/4" hex wrench, snug and tighten the socket
screws in a crossing pattern. Torque to 200–230 in./lbs.
8. Line up the four holes around the outside of the clutch field
with the four set screw holes in the gear housing. The
clutch field wires should be at approximately the 1 or 2
o'clock position.
9. Route the two clutch field wires through the hole and into
the control housing.
10. Carefully slide the clutch field into its bore in the gear
housing until it "bottoms out" within the housing. Do not
pinch the clutch field wires during installation.
11. Thread one of the pointed set screws into its hole. Using
an 1/8" hex wrench, rotate the screw slowly until it contacts
the clutch field. Do not tighten the set screw. The tip of
the set screw should mate with the drill point hole in the
field. Check the clutch field for rotation. If it rotates within
its bore, the set screw is not seated within the drill point.
12. When the set screw is properly seated, install the remaining
three pointed set screws. Do not tighten the set screws.
13. Using a crossing pattern, tighten each of the pointed
setscrews until they are snug. Once all four pointed set
screws are snug, use a crossing pattern to tighten and
torque the set screws to 70–80 in./lbs.
IMPORTaNT: It is very important to evenly snug, tighten,
and torque the clutch field pointed set screws in a crossing
