Two key components of the Valvetronic valve train are produced as castings -- the
intermediate lever arm and the
finger follower.
- The design and production of both
parts was a collaborative effort between BMW designers and Hitchiner
casting engineers in New Hampshire, going from initial design to full production(10,000
pieces per day) in a 2
year cycle.
- Hitchiner also machines, finishes, and assembles the valve
components with installed bearings.
