Abstract
A switchable finger follower, including an inner lever and an outer lever. The outer lever is mounted for pivoting movement to the inner lever. A coupling device is located on one of the inner or outer levers and has a locking pin arranged to move between a locking position, in which the inner and outer levers are connected together for movement in an activation direction, and an unlocked position, in which the inner lever is pivotable relative to the outer lever. A coupling projection is located on the other of the inner or outer lever. The locking pin engages beneath the projection in the locking position, and the locking pin includes a flat at a defined flat height that contacts the coupling surface in the locking position and is selected from a number of locking pins having different flat heights to set a desired mechanical coupling device lash.
