On Model 44 rear axles, the model number is cast into
the upper surface of the left side reinforcing rib of the
housing (fig. 2F-2). On the Model 60 rear axle, the model
number is cast into a boss on the lower right side of the
housing, adjacent to the housing cover.
The axle build date and manufacturer part numbers
are stamped on the right-hand tube, adjacent to the
cover (fig. 2F-17). The build date of the axle is as follows.
First number is the month, second number is the day of
the month, third number is the year, the alpha-letter is
the shift and the last number is the assembly line. If
there are two build dates, the latter will be the date in
which the brake components were installed.
