Abstract
A seal for a rotary machine may include an end cap configured to be coupled to the rotary machine. The end cap may define an end face and a bore. The seal may also include a sleeve received through the bore of the end cap and configured to receive a shaft associated with the rotary machine. The seal may also include a collar coupled to the sleeve and configured to couple the sleeve to the shaft associated with the rotary machine. The seal may further include a spacer coupled to the end face of the end cap, in a first position, such that at least a portion the spacer is between the collar and the end face of the end cap, and, in a second position, such that the portion of the spacer is not between the collar and the end face of the end cap.
