1. Perform the Pressure Relief Procedure.
2. Locate the wire that exits the rear of the pressure control
housing and connects to the wire harness on the engine.
Disconnect this wire from its connector at the engine wire
harness.

6. Locate the clutch armature assembly on the end of the
engine shaft. Note the two set screws as well as the
unused, threaded hole in the taper lock bushing at the
center of the clutch hub.
7. Using an 1/8" hex wrench, remove the two set screws
from the taper lock bushing
8. Thread one of the set screws into the unused, threaded
hole on the taper lock bushing. As the screw tightens,
the bushing will loosen. Once the bushing has loosened
enough, slide the clutch armature assembly off the engine
shaft.
9. Before replacing the clutch
hub and armature assembly
the proper "set back" must be
created. Using the Titan hub
set-up tool (P/N 0555926),
create a "set back" of 0.10"
between the friction surface
of the clutch armature and the
forward face of the clutch hub.
NOTE: a new clutch hub and
armature assembly will
come pre-assembled, but
the "set back" may not be
correct. The "set back"
must still be created using
the hub set-up tool.
10. To replace the clutch armature assembly , line up the
three holes in the taper lock bushing with the three holes
in the clutch armature and insert the bushing into the
center of the clutch armature.
11. Line up the key on the taper lock bushing with the keyway
on the engine shaft and slide the assembly onto the shaft
with the holes facing out.
12. Apply blue Loctite to the two set screws and insert the
screws into the taper lock bushing. Tighten the set screws
only two turns at this time.
13. Using the clutch set-up tool
(P/N 0555926), position
the clutch armature on the
engine shaft. Hold the
tool across the face of the
clutch housing so that the
center, recessed portion
of the tool straddles the
clutch armature assembly.
