Introduction
How To Use The Illustrated Parts List
Ordering Spicer® Parts
• This parts book is organized in sections according to parts servicing requirements. Use the Contents or page headings and colored tabs to
find information.
• Use this book to order parts for your Spicer Axle.
• For convenience, part numbers have been included for all pieces of the carrier assembly. Some of these parts, such as the carrier and caps,
are serviced only in kits or assemblies. Part numbers are for your reference only. Those parts not serviced separately are identified with
NSS.
Kits and Assemblies
• Kits and Assemblies contain groups of individual or assembled parts developed for optimal replacement or repair of a service problem.
• See the Appendix for detailed information concerning kits applicable to this model.
Abbreviations
• AR - As Required - Parts that vary in quantity with each axle. Example: shims
• NSS - Not Serviced Separately - Items which can only be purchased in sets, kit form or service assemblies. Example: ring gear
• RH/LH - Right Hand/Left Hand - Determined as viewed from behind the vehicle looking forward.
• RTV - Gasket Compound - Formed-in-place gasket sealer. It is recommended for use on all surfaces requiring a gasket.
• Assy - Assembly
• Brg - Bearing
• Diff - Differential
• Hsg - Housing
• Inv - Involute
• Str - Straight
Illustrations
• Illustrations show parts in assembly groups.
• Item numbers on illustrations correspond with parts listings on pages that accompany the drawings
• Notes are included on illustrations where additional is needed.
Parts Listings
• Parts listings are defined by parts groupings and are broken down by service assemblies.
• Parts Listings identify a part for servicing with the following categories:
• Item - corresponds with numbers on illustrations for part identification
• Description - specifies part name or description
• Quantity (Qty) - quantity required for assembly
• Order Part No. - service part numbers are broken down by model, type or other applicable information
• Notes - define unique characteristics or requirements
• Kits And Assemblies - order the part numbers indicated
* Other pertinent information is listed in tables or parts listings as required.

Introduction
Model Identification
Locating Model Designation Information
• Axle Model Identification, Part Number and / or Serial Number are located on the axle centerline. This information will help to locate
information in this book and to identify the correct parts for servicing.
• Axle Housings are identified by the specification number stamped on the rear right-hand side of the axle housing. This number identifies all
components of the axle as built by Spicer, including OEM special requirements such as yoke or flange. Some axles may also include an
identification tag as shown.
Axle Specification Number
• The axles illustrated in this book are found on a number of different axle shafts, according to OEM specifications.
When ordering replacement axle shafts, note the part number stamped into the flange.

Introduction
Model Identification
Using Model Designation to Identify Axle Components
• The Axle Model identification number contains information that is important to understand when purchasing service parts or new components.
The Model identification number provides important vehicle, capacity and application information and model features. Use this guideline to
understand your axle model Identification. If you need assistance, contact your Dana representative.

Older Model Serial Numbers
• Units built before May 1987 were identified with a date coding system. Carrier assemblies produced after this date are assigned unique
serial numbers. Serial numbers are stamped into the carrier casting or contained on a metal tag attached to the carrier.

New Oil Seals for Input and Output Yoke Assemblies
Starting in the 1st quarter of 1994, Spicer will begin servicing all 461,521,581,601,651 Axle Models with new Microlip Oil Seals. This product
improvement will supersede existing Yoke/Slinger Assemblies. Using Oil Seal Driver Kits is reccommended. The charts below show part
supersession from "OLD" to "NEW" Yoke/Slinger Assy's and include other information concerning the inter-changeability of the "OLD" and
"NEW" parts.
Basic Overhaul kits, Bearing kits with Oil Seals and other kits that have the old seals in them will be updated to include the new seals – these
are still compatible with the “OLD” Yoke/Slinger assemblies.
New Yoke/Slinger Assemblies on Forward Axles must use the Microlip seals at the D-Output and D-Input, as result, the “NEW” Yoke/Slinger
kits for Forward Axles will include the Microlip seal.
The Rear Axle pinion Yoke/Slinger assemblies will not contain Microlip seals – for Rear Axles you may use the “NEW” Yoke/Slinger assemblies
with either the old Triple Lip seal or the new Microlip seals.
If you have any questions call your Dana representative.
