Claim 14:
15. A method of performing a lockout operation to torque and lock a drive train within a gearbox, the method comprising:
detaching a cover from its coupling to a housing, the housing comprising a hole therethrough and configured to be fixedly coupled to the gearbox;
uncoupling the cover from a shaft, the shaft configured to pass through the hole and comprising a first plurality of teeth at one end and a socket head on a distal end, the shaft configured to be translatable along its axis, wherein coupling the shaft to the cover prevents the shaft from engaging the drive train;
manipulating the shaft so as to engage a second plurality of teeth on the drive train with the first plurality of teeth so as to transmit rotation from the shaft to the drive train;
applying a torque to the drive train by rotating the socket head; and
rotating a plurality of threaded bolts coupled to a plurality of threadless holes in an inner collar and a plurality of threaded holes in an outer collar, the inner collar configured to sit around the shaft and at least partially between the shaft and the housing, the outer collar configured to sit around the shaft and at least partially between the inner collar and the housing, wherein rotating the plurality of threaded bolts can adjust the relative position of the inner collar and the outer collar, wherein as the inner collar and the outer collar are pulled closer together the inner collar is pushed against the shaft and restricts a displacement of the shaft within the hole.
