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. 25.
7. After installing the rotor (51a) the air gap must be
adjusted between the rotor and the field (53). Use
shims provided with the clutch repair kit. Push the
shims between the rotor and the field. Tighten the
setscrews (58) oppositely and evenly. Drag on all
four shims must be even. Pull the shims out. Pull
the engine recoil rope to assure that the engine
turns freely, and there is no contact between 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 186–857) to set
the proper gap. This spacer is for use only during
installation.
Torque the screw to 7 ft–lb (9.5 N.m).
The face must be clean.

Reassembly
8. Clean the face of the armature (51b). With the flat
side of the armature facing the rotor (51a), slide
the armature onto the hub (2h) in the drive/pinion
assembly (D) just until the chamfered end of the
hub (2h) protrudes through the armature. See
Detail B, Fig. 25. There will be significant resis-
tance. Attach the cardboard spacer, supplied with
the clutch kit, to the face of the armature. Engage
the tabs on the spacer with the slots in the arma-
ture or bend tabs over outside diameter of arma-
ture.
Brace the cart against a wall to keep it from rolling.
Push the drive/pinion assembly onto the clutch
housing (1). There will be significant resistance.
When the mating surfaces of the drive/pinion as-
sembly and the clutch housing (1) are flush, re-
move the drive/pinion assembly. Remove the
cardboard spacer.
9. Assemble the drive assembly (D) to the clutch
housing (1), using the capscrews (59) and lock-
washers (16). See Fig. 25.
