A limited rotation roller tappet having an aperture and a slot formed in it. A locking bar having a narrow end portion and a shoulder portion prevents rotation of the tappet. The end portion of the locking bar is adapted to pass through both the aperture and the slot while the shoulder portion will not pass through the aperture. The locking bar preferably has a second narrow end portion and is held in place by a second similar roller tappet adjacent to the first having a slot through which the second end portion passes and an aperture through which the shoulder portion will not pass.
