Reassembly

6.Be sure the face of the rotor (4b) and the field are free of all oil and contaminants. Remove any burrs on the outside edge of the rotor. Install the rotor, lockwashers (11) and capscrews (16). Torque the capscrews to 125 "10 in-lb (14 "1.1 N￿m). See Fig. 20.

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 "3 in-lb (3.1 "0.3 N￿m).

7.Be sure the face of the armature (4a) is clean. Assemble the armature to the shaft in the pinion housing (19). A retaining ring located within the armature makes it difficult to assemble these parts. Follow this procedure for the best results. First, lock a few splines of both parts. While they are locked, use a screwdriver to gently push the retaining ring into the armature, and finish engag- ing the splines. Push the armature onto the shaft until it contacts the ring (19m). See Fig. 20.

8.Assemble the pinion housing (19) to the clutch housing, using the capscrews (10) and lockwash- ers (11). See Fig. 20.
