The drive or pinion spindle can be rotated in either direction at a recommended spindle speed of 600 RPM. It is mounted in a head which is vertically adjustable on a column, so that the spindle can be offset either above or below the center line of the gear spindle for testing hypoid gears. The pinion head column is adjustable angularly in a horizontal plane to permit testing of gears of any shaft angle from 0 - 135 degrees.
