Abstract
A shaft assembly includes a shaft with a first radial shoulder and a second radial shoulder. A retainer plate is located at least partially between the first radial shoulder and the second radial shoulder to avoid damage when an impact load is applied to the shaft. A spring assembly biases the shaft out of contact with the retainer plate during operation.
