Supplementing generator armature information in the April Service Bulletin some of the first A-10005-C armature shafts were made with a 7/8” taper on the pulley end of the shaft. This is the same taper that was used on the A-10005-BR armatures which is illustrated in Fig. 878, April Service Bulletin.
When mounting the present design generator pulley A-10130-B on one of these shafts, it will be necessary to place special service washer A-10144-R next to face of pulley in the same manner as shown in Fig. 881, April Bulletin.
