The axle Models-Carriers-Features Chart inside this front cover lists all the variations of the carriers covered in this : The carriers listed in this catalog do not include yokes. A yoke is a major assemblydifference, so a carrier sold with a yoke has a different assembly level number than the samecarrier without the charts for carriers, output shafts, and axle housings include the following information:yAn exploded view of each assembly, keyed to the Parts description of each that are sold as assemblies that include other carriers or axle models the part is used quantity of the part used on the carrier or part number of each the part is available in a Parts : Determine which Chart and Figure (1 or 2) applies to your carrier by using thefollowing sources of information:yIdentification tag installed on the Models-Carrier-Features and descriptions of the carriers inside the front cover and at the beginning of Chart 1and Chart (Thru) Shafts.

3 This chart covers the output shafts for the forward axles of all that the output shaft assembly or its components are only sold as separate items. The outputshaft is not included with the purchase of a carrier or 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 endseries (L Series or R Series ) that are used on 140, 141 and 145 Series Shafts: The axle shafts are grouped in sets ( and ) according to the axle models theyare used on. Many axle shaft sets are used on more than one axle model. The axle shafts are alsolisted by part number with and Flanges: There are four charts that cover full round bearing yokes, wing bearingyokes, Easy Service yokes, and flanges. Each chart lists the yokes or flanges used on each axlemodel.

4 The yokes and flanges are listed by : 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 Parts Index: This lists every part number in the catalog along with the page(s) on whichthe part is listed.
