Critical dimensions on the wax pattern are checked prior to pattern assembly.

Critical tolerances on the bearings are automatically measured.

The slope of the  profile is gauged and the lever arms are classified into six tolerance bands (8 micron span) so that matched sets are installed into a given engine.

The alignment and contour of the bearing pads are 100% inspected by a coordinate measuring machine.

The casting is visually inspected for surface quality and bearing operation after assembly.
