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.

FAQs

How does the catalog help determine the correct carrier configuration?

Use the identification tag on the carrier and cross-reference the Axle Models-Carrier-Features Chart plus the carrier pictures and descriptions shown in Chart 1 and Chart 2.

What information do the carrier, output shaft, and axle housing charts provide?

They include exploded views keyed to the parts list, part descriptions, which assemblies include other parts, which carriers or axle models the parts are used on, quantities used, part numbers, and whether parts are available in kits.

Are yokes included in the carrier listings?

No. The catalog notes that carrier listings exclude yokes; carriers sold with a yoke have a different assembly level number than the same carrier without the yoke.
