Reassembly

NOTE:  Refer to Fig. 31 for Steps 5–9.

5.

Place the engine (45)  on the cart. Align the mount-
ing holes. Guide the engine wire (A) and wiring har-
ness (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), lockwash-
ers (6) and washer (7) from under the engine mount-
ing plate to secure the clutch housing (17). Connect
the like-colored wires as shown in the Detail A.

6.

Be sure the face of the rotor (9a) and the field (10)
is free of all oil and contaminants. Install the rotor,
lockwashers (2) and capscrews (4). Torque the cap-
screws to 7 ft–lb (9.5 N.m).

After installing the rotor (9a), pull the engine recoil
rope to assure that the engine turns freely and there
is no friction between the rotor (9a) and the field (10).
If there is friction, loosen the setscrews (16) and re-
position the field (10) as necessary. Tighten the
setscrews oppositely and evenly to 25 in–lb
(2.8 N.m). Also make sure there are no burrs on the
outside edge of the rotor.

7.

Be sure the face of the armature (9b) is clean. As-
semble the armature to the shaft in the pinion hous-
ing (C). A retaining ring located within the armature
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 engage the remain-
ing splines. Push the armature onto the shaft until it
contacts the ring.

8.

Assemble the drive/pinion housing (C) to the
clutch housing, using the capscrews (3) and lock-
washers (2).

9.

Connect the cord set (62) to the pressure control.
