Abstract
A planet carrier assembly has staking pockets for retention of the pinion pins. The staking pockets are substantially rectangular when viewed from the top view but display a ramp angle when viewed from the side view. The shape of the pocket provides for improved pinion pin retention within the planet carrier side plate while reducing the required staking forces.
