Abstract: A method of aligning a property for testing in a dynamometer cell is provided, including the steps of: mounting a laser travel car to each of four risers in a repositionable manner; mounting a laser to each of the laser travel cars in a repositionable manner; securing a dyno cart into a cart receiving station between the four risers; calibrating each of the lasers; preparing the dyno cart to receive the property; mounting the property to the dyno cart; orienting the various lasers based, at least in part, upon predetermined optimal alignment dimensions to thereby provide a set of target locations; orienting the property such that predetermined locations of the property align with the set of target locations to ensure appropriate property orientation during testing; and removing the dyno cart from the cart receiving station for delivery to the dynamometer cell.

Abstract: An engine camshaft assembly includes a hollow tubular shaft mounting a plurality of separate cam sets, each including multiple camps. Each cam includes an outer cam surface bounded by opposite parallel sides and including an axial opening extending through said sides. Each cam set includes at least two associated cams positioned in side-by-side relation with their openings axially aligned. A shoulder protruding from a side of one of the cam engages an adjacent side of another associated cam, thus maintaining the sides of the associated cams in fixed parallel relation. The tubular shaft extends through the cam openings and supports the cam sets on a common rotational axis. During assembly, the shaft is expanded into engagement with the openings so that the cam sets are retained in fixed axial and angular relation on the shaft.
