Abstract

A switching roller finger follower, including: first and second rotatable outer arms; and a locking mechanism including a locking pin with a first outside diameter and first and second ends. The locking mechanism includes first and second locking sleeves: separate from the locking pin; fixedly secured to the first and second ends, respectively; and having second and third outside diameters, respectively, larger than the first outside diameter. The locking pin is displaceable such that: in a locked mode, the first and second locking sleeves contact the first and second outer arms, respectively, to block rotation of the first and second outer arms in a first rotational direction; and in an unlocked mode, the first and second locking sleeves are free of contact with the first and second outer arms, respectively.
