Abstract
A planetary gear system and a pin for coupling a planet gear to a carrier in a planetary gear system are disclosed. The planetary gear system includes a planet gear defining a central planet axis, a carrier disposed adjacent the at least one planet gear, and a pin extending from the carrier through the planet gear generally along the central planet axis. The pin includes a first end, a second end, and an outer surface extending therebetween. The pin further defines an opening extending from the outer surface generally along the central planet axis and at least partially through the pin.
