ABSTRACT:
To permit manufacture of starter components with substantial tolerance, while maintaining the axial play of the armature of the starter within tight tolerances, and permit adjustment of the tolerance of the axial play after assembly of the starter component together, an end face (33) of the shaft (4) projects beyond the respective end bearing, which is retained a housing projecting beyond the bearing by the distance of an adjustment plug (29) slightly smaller than the longest shaft--in the light of tolerances--of the starter. An axial play compensation spacer in form of a washer or disc (FIG. 2--35), a ring (FIG. 3--35a) or a centrally held ball (FIG. 4--35b) is placed between the end face (36) of the plug and the end face (33) of the shaft, the plug being formed with an abutment surface (31) which engages an engagement surface (32) at the outside of the housing adjacent the bearing. The plug is threaded in the direction of rotation, so that, upon once being securely seated, it will remain securely seated, thus maintaining the position of the shaft in axial direction.
