Topic: New Design PDU Cover & Outer Pinion Support Bearing for 46,000 LB Tandem Family of

Axles

Affected Models: All DSS/DDS40-(P), D461/462/463/521/581/583/601/651/652-(P)

In February 2000, a product upgrade was made to the power divider section of the models listed above. The outer pinion

support bearing was upgraded from a three-piece bearing assembly & snap ring design to a one-piece roller bearing

design. The new bearing part-no. 120080 has a higher load capacity and the assembly procedure is now simplified.

As part of the change, new production power divider

covers 129965 (pump models) & 129969 (non-pump

models) were released. The 120080 bearing can only

be used with these new covers. The older power divider

covers that are machined with a snap ring groove are no

longer available and are replaced in service by Power

Divider Cover kits. The new kits will also include the new

120080 support bearing. The older design bearing parts

(78916 & 78937) will remain available for service as

shown on the chart below.
