In February 2000, a product upgrade was made to the power divider section of the DSS/DDS40(P) models. 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) and 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 and 78937) will remain available for service as shown on the chart below.
Shown below is a quick reference chart for power divider cover castings for both “pump” models and “non-pump” models.
