Abstract
A system and method for facilitating the reduction or elimination of end play associated with an armature in an electric motor is disclosed. The system and method utilize an end play assembly which includes a housing having an integrally molded lock for retaining a screw in an unengaged and locked position. The end play assembly also includes a coil spring which urges the screw towards an engaged and unlocked position when the end play assembly is mounted in a housing of the electric motor. The lock includes at least one wing portion which engages a notch on the housing of the electric motor such that when the end play assembly is mounted in the motor housing, the notch forces the lock into the unlocked position which releases the screw so that the spring can urge, rotate or screw the screw to cause a screw end to be forced into engagement with the end of an armature of the electric motor. Advantageously, the end play assembly continuously and automatically adjusts for the end play to reduce or entirely eliminate any end play.
