Clutch - Graco Roof Rigs 224483 Instructions-Parts List Manual

NOTE: The clutch assembly (9) includes the armature
(9b) and rotor (9a). 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.
Otherwise, start at Step 5.
1. Relieve the pressure.
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 away; the
armature (9b) will come with it.
