Field Coils

Mount starter frame in press-type screwdriver stand and remove pole piece attaching screws. Remove pole pieces and field coils. Prior to installing new coils, heat windings to 122°F in order to obtain added flexibility and facilitate seating the coils under pole shoes. Use press-type screwdriver stand to completely tighten attaching screws. After installation is completed, measure pole shoes inner diameter. To assure proper air gap between pole shoes and armature, inner diameter must be between 2.175-2.182" (55.25-55.42 mm) on starter No. E 84-0.8/12 and between 2.675-2.677" (67.95-68.00 mm) on starter No. E 100-1.3/12. Do not bore out inner diameter to obtain specified diameter. If diameter is not within tolerance, coils and shoes have been improperly installed.
