ABSTRACT:
An outer collar on a power takeoff yoke sleeve locks against an inner collar to rotate the yoke and sleeve in a first direction to align splines within the sleeve with splines on a power takeoff stub shaft. Cooperating teeth between the inner collar and the outer collar permit the outer collar to rotate freely in the opposite direction. The outer collar surrounds the inner collar and detent operators and the small end of a ball which protects the yoke from unintentional contact. The outer collar is grasped and is slightly turned to align the yoke splines and stub shaft splines while pushing the outer collar toward the stub shaft to slide the sleeve over the stub shaft. The stub shaft pushes a detent holdout longitudinally and releases the detent to move inward into a groove on the stub shaft. A heavy spring on the sleeve pushes a detent operating and locking device axially to move the detent inward into the groove in the stub shaft. Pulling axially outward on the sleeve pushes the detent actuator axially, releasing the detent to move radially outward as the sleeve is pulled off of the power takeoff stub shaft. A spring between the detent actuator and the outer collar returns the outer collar axially towards the open end of the sleeve.
