WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 6.
NOTE: The clutch assembly (4) includes the armature
(4a) and rotor (4b). The armature and rotor must
be replaced together so they wear evenly.
NOTE: If the pinion assembly (19) is not yet separated
from the clutch housing (2), follow Steps 1. to 4..
Otherwise, start at Step 5..
1. Relieve the pressure.
2. Disconnect the hose (59) from the outlet nipple (49)
of the displacement pump. Remove the spring clips
(100, 102) and bypass hose (101).
3. Remove the bottom two screws and lockwashers
(10, 11) from the back of the clutch housing (2) and
then remove the remaining three of screws and
lockwashers.

with a plastic mallet to loosen the assembly (D) from
the clutch housing (2). Pull the assembly away.
5. The armature (4a) will come with the assembly (D).
Remove the armature from the hub (19h)
6. Remove the four socket head capscrews (16) and
lockwashers (11).
7. There are two ways to remove the rotor (4b).
a. Install two of the screws in the threaded holes in
the rotor. Alternately tighten the screws until the
rotor comes off. See Fig. 25.
b. You can use a standard steering wheel puller.
However, two 1/4–28 x 3 or 4 in. long screws (B)
are also needed. Replace the short screws of the
steering wheel puller with the 3 or 4 in. long
screws. Turn the screws (B) into the threaded
holes of the rotor (4b). Tighten the capscrew (C)
of the tool until the rotor comes off. See the Detail
in Fig. 25.
