7. Record the pinion depth code on the head of the
drive pinion. The number indicates a necessary
change in the pinion mounting distance. A plus
number indicates the need for a greater mounting
distance (which can be achieved by decreasing
the shim thickness). A minus number indicates
the need for a smaller mounting distance (which
can be achieved by increasing the shim
thickness). If examination reveals pinion depth
code “0”, the pinion is “nominal”.
