NOTE: Refer to Fig. 29 and 30 for Steps 5 to 7.
5. Place the engine (45) on the cart. Align the
mounting holes. Guide the engine wire (A) and
wiring harness (69) through the mounting plate
grommets (8). Install the screws (42) and nuts (43)
and torque to 15 ft-lb (20 N.m). Install the
capscrews (5), lockwashers (6) and washer (7)
from under the engine mounting plate to secure
the clutch housing (17). Connect the like-colored
wires as shown in Fig. 29.
6. Be sure the face of the rotor (9a) and the field (10)
is free of all oil and contaminants. Install the rotor,
lockwashers (70) and capscrews (72). Torque the
capscrews to 7 ft-lb (9.5 N.m).
After installing the rotor (4b), check the clearance
between the outside diameter of the rotor and the
inside diameter of the field. The clearance must be
at least 0.010 in. (0.25 mm) all the way around.
Use shim stock or feeler gauge. If necessary,
loosen the setscrews (12) and reposition the field.
Tighten the setscrews evenly to 27 in–lb (3.2 N.m).

Be sure the face of the armature (9b) is clean.
Assemble the armature to the shaft in the pinion
housing (C). A retaining ring located within the ar-
mature makes it difficult to assemble these parts.
For the best results, first engage a few splines of
both parts, then use a screwdriver to gently push
the retaining ring into the armature, and then en-
gage the remaining splines. Push the armature
onto the shaft until it contacts the ring.
7. Assemble the drive/pinion housing (C) to the
clutch housing, using the capscrews (3) and
lockwashers (2).
8. Connect the cord set (62) to the pressure control.
