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, follow Steps 1 to 4. Other-
wise, start at Step 5.
1. Follow the Pressure Relief Procedure Warning
on page 12.
2. Disconnect the hose (55) from the displacement
