There are three ways to align the pinion skew to the girth gear; 1) Using the pitch lines 2) Setting root clearance 3) Setting backlash (only applicable to a new gear and pinion). Measuring the root clearance is best done using Babbitt or lead slugs. Use % 1" diameter Babbitt slugs about 1 to 2" in length.
