Claim:
1. A starter assembly, comprising: a pinion; an output shaft to transmit rotation to a drive assembly ring gear via the pinion and including a first helical spline having a first angle directed reversely with respect to a direction of the rotation; a clutch assembly operatively connected to the output shaft, the clutch assembly including helical spline elements having a second angle that is greater than the first angle; and an elastic element anchored on the first helical spline to bias the pinion in an axial direction, the ring gear and the pinion including complementary teeth, and the pinion defining a bore with a second helical spline having a third angle that registers with the first angle of the first helical spline such that the pinion teeth are forwardly rotated into respective engagement positions with the ring gear teeth as the output shaft and the first helical spline move axially relative to the pinion in the axial direction.
