5 HOW TO USE THIS CATALOG There are 51 basic carriers covered in this catalog: 3200-R T N M P F M U S P R H X V Z R S J L W A D T K G C B E Z L X D C F B W L E D G C M F E H D Q G G M E-1981 Major assembly differences such as oil pumps, main diff. locks, etc. are indicated by the different assembly level numbers as well as the base carrier part number. The Axle Models-Carriers- Features Chart on Page 2 lists all the variations of the carriers covered in this book. 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. The charts for carriers, output shafts, and axle housings include the following information: An exploded view of each assembly, keyed to the parts list. A description of each part. Parts that are sold as assemblies that include other parts. Which carriers or axle models the part is used on. The quantity of the part used on the carrier or axle. The part number of each part. Whether the part is available in a kit. Carrier Parts: Determine which Chart and Figure (1 or 2) applies to your carrier by using the following sources of information: Identification tag installed on the carrier. Axle Models-Carrier-Features Chart. Pictures and descriptions of the carriers inside the front cover and at the beginning of Chart 1 and Chart 2. Output (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. Housing 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 and the two wheel end series (L Series or R Series) that are used on 140, 141, 143, 144 and 145 series axles. Axle Shafts: The axle shafts are grouped in sets (L.H. and R.H.) according to the axle models they are used on. Many axle shaft sets are used on more than one axle model. The axle shafts are also listed by part number with dimensions. Yokes and Flanges: There are five charts that cover full round bearing yokes, wing bearing yokes, Easy Service yokes, RPL yokes and flanges. Each chart lists the yokes or flanges used on each axle model. The yokes and flanges are listed by dimension. Kits: The first chart lists all the kits available for each axle model and carrier. Following that chart, the kits are listed in numerical order, and the contents of each kit is listed. Numerical Parts Index: This lists every part number in the catalog along with the page(s) on which the part is listed.

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.

7 Rear Drive Axles Model Numbers and Designations - OLD STYLE 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.

Larger numbers indicate a higher GCW rated carrier: i.e., larger ring gear, etc. (Also see Tridem Axle Note 2 below.) Axle Design Variation Indicates axle design level or variation, (e.g., RS has a thicker wall housing than the RS ). For information see the Bill of Material for that specific axle model.
