Carrier Assembly
Serial Numbers
Starting in May of 1987,6SLFHUbegan
assigning serial numbers
to carrier assemblies, instead of the
date code currently used. These
serial numbers will be stamped into
the carrier casting.
The carrier assembly serial number
will consist of ten characters; a
letter followed by nine numerals. A
sample carrier assembly serial
number is shown below.
H871200001
H871200001
Unique number
Day of Year (1 -365)
Year
Production Plant
The letter designation indicates the
producing plant; either an “H” for
our Henderson, Kentucky plant, or
“G” for our Glasgow, Kentucky
plant. A five digit Julian date code
follows, the first two digits indicating
the year, and the last three indicating the day of the year. The last four
digits are a number unique to each
axle.

6x6 Drive System
In 1988, 6SLFHU changed its current production model nomenclature to
incorporate the design level of the basic axle used in the All Wheel Drive
System. Service parts remain available for past production models where
applicable, these past production models have been included in this publication or can be serviced with a current model.
The matrix below has been designed to help you locate the correct parts list
for the model being serviced.
1. Locate the model series you are servicing in the left column.
2. Determine the correct gearing you are servicing (Single Reduction, Single
Reduction with CTD, Dual Range, Planetary Double Reduction) in the other
column heads.
3. You will find the model used in this publication by moving from identified
model being serviced in column one across to the correct gearing.
