Note where Old and New Pinion Marking columns intersect. Intersecting figure represents plus or minus amount needed.
Note the marked number on the face of the drive pinion gear (-1, -2, 0, +1, +2, etc.). The numbers represent thousands of an inch deviation from the
standard. If the number is negative, add that value to the required thickness of the depth shim(s). If the number is positive, subtract that value from the
thickness of the depth shim(s). If the number is 0 no change is necessary Refer to the Pinion Gear Depth Variance Chart.
