HOW TO USE THIS CATALOG
yThere are 11 basic carriers covered in this catalog:
3200-C-1381 3200-K-1753 3200-S-1839
3200-U-1399 3200-W-1791 3200-A-1899
3200-M-1625 3200-J-1804 3200-L-1910
3200-J-1752 3200-M-1833
Major assembly differences in a carrier are indicated by the different assembly level numbers in front
of the base carrier number, for example, A1-3200-J-1804 and A4-3200-J-1804.
NOTE: The carriers listed in this catalog do not include yokes. A yoke is a major assembly difference, so,
a carrier sold with a yoke has a different assembly level number than the same carrier without the yoke.
yThe charts for carriers, output shafts, and housings include the following information:
yAn expoded view of each assembly, keyed to the parts list.
yA description of each part.
yParts that are sold as assemblies that include other parts.
yWhich carriers or axle models the part is used on.
yThe quantity of the part used on the carrier or axle.
yThe part number of each part.
yWhether the part is available in a kit.
yCarrier parts:
Determine which chart and figure (1 or 2) applies to your carrier by using the following sources of information.
yIdentification tag installed on the carrier.
yAxle Models-Carriers-Features Chart.
yPictures and descriptions of the carriers inside the front cover and at the beginning of Chart 1 and Chart 2.
yOutput (thru) shafts:
This chart covers the output shafts for the forward axles of all tandems. Note that the output shaft assembly
or its components are only sold as separate items. The output shaft is not included with the purchase of a carrier
or housing.
yHousing Assemblies and Wheel End Parts:
This chart covers the housing assemblies and wheel end parts for all axles. The parts are listed according to
axle models that are used on 180 and 380 series axles.
yAxle shafts:
The axle shafts are grouped in sets (L.H. and R.H.) according to the axle models they are used on. Many axle
shafts are used on more than one axle model. The axle shafts are also listed by part number with dimensions.
yYokes and Flanges:
There are four charts that cover full round bearing yokes, wing bearing yokes, Easy Service yokes and flanges.
Each chart lists the yokes or flanges used on each model, the yokes and flanges are listed by dimensions.
yKits:
The first chart in this section lists all the kits available for each model axle and carrier. Following that chart,
the kits are organized in numerical order.
yNumerical Parts Index:
This section lists every part number along with the page(s) on which the part is listed.

The part number supercessions listed here reflect product improvements made in several key areas.
Several of these product improvements are non-interchangeable at the component level, in these
cases kits have been developed to ease your transition to the new designs.
The rear-rear and single axle carriers with main diff. lock now have a screw-in type shifter.
The forward-rear carriers with pump now have an internal pump that is also used on the
145 and 160 family axles.
The forward-rear carriers also now have a screw-in type I.A.D. lock shift cylinder.

Rear Drive Axles
Model Numbers and Designations
Axle models are identified by a letter and number system.
The letters and numbers give important information about the
specific axle model.
The first seven positions of the designation identify a basic axle
model, while the second group of letters and numbers identify
particular specifications.

Axle Design Variation
Indicates axle design level or
variation, (e.g., RS 23 161 has a
thicker wall housing than the RS
23 160). For information see the
Bill of Material for that specific
axle model. (Also see Tridem
A
xle Note 2 below.)
Carrier Type
Carrier size. Larger numbers
indicate a higher GCW rated
carrier: i.e., larger ring gear, etc.
(Also see Tridem Axle Note 2
below.)
Nominal Axle Load Rating (GAWR):
In thousands of pounds. Individual forward
and rear axles of a tandem set (D, N, P, R)
are rated as single axles. A tandem set (T) is
rated as the combination of the two axles and
a tridem set (Z) as the combination of the
three axles.

We warrant all new parts for one year from date of shipment to the buyer against defective material or
workmanship (but not against damage caused by accident, abuse or improper installation, maintenance
or repair) when such parts are used on vehicles the specifications of which have been approved by our
Engineering Department.
As the exclusive remedy under this warranty, we will, at our option, repair or replace such parts free of
charge, or take back the nonconforming parts and refund the monies paid by buyer for such parts, if
found on examination by us to be nonconforming and if any necessary return charges are prepaid.
If it is necessary to return any parts under this warranty, buyer agrees not to make any deduction on
account thereof from remittances on current accounts while claims are in the process of disposition.
Any expense incurred without our consent for repairs or replacement will not be allowed.
THIS WARRANTY IS EXPRESSLY IN LIEU OF ALL OTHER WARRANTIES OR CONDITIONS,
EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY IMPLIED WARRANTY OF
MERCHANTABILITY OR FITNESS FOR PARTICULAR PURPOSE. IN NO EVENT SHALL SELLER
BE LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY NATURE.
