6. Be sure the face of the rotor (51a) and the clamp
(55) are free of all burrs. Install the rotor, lock-
washers (16) and capscrews (57). Torque the
capscrews to 7 ft–lb (9.5 N.m). See Fig. 23.
7. After installing the rotor (51a) the air gap must be
adjusted between the rotor and the field (53).
Tighten the setscrews (58) oppositely and evenly.
Pull the engine recoil rope to assure that the
engine turns freely, and there is no contact be-
tween the rotor and the field. If there is contact,
loosen the setscrews and reposition the field.
NOTE: With the autogap style armature, the gap be-
tween the rotor and the armature is critical for proper
operation. The clutch kits with an autogap style arma-
ture include a cardboard spacer (p/n 186857) to set
the proper gap. This spacer is for use only during
installation.
