Abstract: A slip bearing for a power takeoff shaft wherein a sleeve is placed between the socket and shaft of the power take off. A retaining ring, inserted in grooves formed on the inside of the shaft, is used to hold the nylon sleeve in the shaft.

Abstract: A push-pull collar or a yoke sleeve ramps locking pins radially outward when the collar is pushed away from a power takeoff stub shaft so that the yoke sleeve may be removed from the shaft. The pins engage detents in the ramps to hold the pins outward and to hold the collar axially inward on the yoke sleeve. Pushing the sleeve on a shaft locks the pins, releasing the collar. When the pins move inward in engagement with a shaft groove, a spring moves the collar axially outward, partially covering the pins to hold them in an inward, locked position.

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.
