A pinion assembly (30) for an electrical starter motor (20) includes a metallic pinion nut (4) threadedly received on an output shaft (22) of motor (20). A first bushing (36) includes a radially extending annular flange (40) which is fixed to and covers nut (4) and a cylindrical axially extending shell (42). A metallic drive pinion (32) is supported on shell (42) and is electrically insulated from shaft (20) by shell (42) and from nut (4) by annular flange (40). However, slip clutch (14) is located between first bushing (36) and drive pinion (32) to transmit torque therebetween. Finally, cylindrical member (62) retains drive pinion (32) on bushing (36).
