Abstract
A method of manufacturing spring pallets of a switchable roller finger follower. The method includes the steps of forming the spring pallets of the roller finger follower as a single unit, forming a material web between the spring pallets, and separating the spring pallets apart from each other. Also, an intermediate assembly of the spring pallets of the roller finger follower is disclosed. The intermediate assembly includes a first spring pallet, a second spring pallet, and a material web which extends between the spring pallets, and adjoins the spring pallets together. Further, a method of manufacturing an inner arm of the switchable roller finger follower is disclosed in which the inner arm is formed by sheet metal, preferably by stamping.
