HAXL-TEC-11.1
D170 AND D190 GENUINE SPICER® OUTPUT SHAFT
BEARING RACE PARTS CHANGE - REVISED
SERVICE/TECHNICAL
DATE: February 13, 2012
TO: All Dana Spicer® Service Parts Heavy Axle Customers
Affected Models: All D170, D190
Dana has made a significant design change to the output shaft bearing components used on the Genuine
Spicer® differential models listed above. Effective the week of October 24th 2011, new size bearing cups
will be utilized resulting in the “repositioning” of the machined snap ring groove on all forward D170 axle
housings and D190 bolt on housing covers. Before the implementation of this change, Dana had been
using an interim configuration since June 2010. In those axle builds a unique combination of parts was
being utilized. This included the use of a “housing spacer” 139979 and a combination of bearing cups
131212 and 139980.
Dana has released a new output shaft bearing kit, axle housing cover kit and all new D170 axle housings.
All original and interim design D170 axle housings are now replaced by new axle housings as shown in the
chart on page 3. When replacing any of the output bearing parts for any configuration in the field, the use
of correct components or kits is important.
The individual bearing parts and service kits are available for any of the configurations that exist in the field
today. These items are detailed in charts on the next page. Chart-N is for the NEW configuration,
Chart-O for ORIGINAL configuration and Chart-I for the INTERIM configuration. A complete D170 axle
housing supersession chart is shown on page 3 of this bulletin.

Exact implementation dates for product changes can vary by OE. Additionally replacement of original product in the
field by customers from previous repairs could be possible. Replacement parts should always be confirmed by
identifying the original removed parts before parts are ordered or installed.
WARNING: DO NOT MIX Parts! Mixing of parts could cause pre-mature failure to the output shaft bearings and associated
parts. Check compatibility of parts before final assembly!

Interim Build Configuration – Original Axle Housing w/ Repositioned Snap Ring Groove and use of a Axle
Housing Spacer:
The 504054 kit shown below was released and used when replacing the bearing parts from axles built with parts used on
an interim basis. From June 2010 thru Sept 6th 2011 axle assemblies used a bearing spacer in addition to the bearing cup
combination of 139980/131212. The snap ring groove location change was introduced but required the use of the spacer
too. Check individual component identification or confirm vehicle build or serial number information if available. This kit
contains a replacement output nut and oil seal.
NOTE: The new 504060 kit can be used as an alternate replacement for the 504054 parts kit, but the housing spacer
139979, inner bearing cup 131212 and original snap ring 078937 MUST NOT be used. Use only the parts supplied in the
504060 kit.

IMPORTANT REPLACEMENT REMINDERS AND TIPS
Always check the individual components for OEM identification numbers as you do replacements. Assembly
or mixing of wrong parts could lead to pre-mature failures. Always check compatibility of parts before final
assembly!
Use replacement charts and reference notes to determine correct replacement parts.
Check with the OEM for vehicle build data if identification of components cannot be done.
Always use Spicer Genuine replacement parts, failure to use Genuine Spicer replacement parts could lead
to pre-mature failures in assemblies and could void any existing warranty on the component or axle
assembly involved.
