NOTE: The clutch assembly (9) includes the armature
(9b) and rotor (9a). The armature and rotor must be
replaced together so they wear evenly.

from the clutch housing, follow Steps 1 to 4. Other-
wise, start at Step 5.
1. Follow the Pressure Relief Procedure Warning
on page 17.
2. Disconnect the hose from the displacement pump.
Disconnect the cord set (62) from the pressure
control.
3. Remove the bottom two screws (3) from the clutch
housing (17) and then remove the remaining three
screws (3).
4. Tap lightly on the back of the bearing housing (23)
with a plastic mallet to loosen the assembly (D)
from the clutch housing (17). Pull the assembly
