Carrier Mounting Flange Design Change
Carrier Mounting Flange Design Change
Beginning June 3rd, 2002, the nominal thickness of the carrier to housing
flange was increased in the DSP40(P), DSP41(P), DDP40(P), DDP41(P),
RSP40, RSP41, RDP40 and RDP41 models. This change required the
use of new fastener parts. A new (45mm) capscrew (P/N 130836) was
released as it replaced both 210173 and 130158 old design capscrews.
Additionally, a much thicker boss was added to the flange at the 12:00 &
6:00 o’clock positions. These new thicker flange bosses require an even
longer (70mm) capscrew (P/N 130837). A thicker and larger diameter
flat washer (P/N 130877) was also released as part of this upgrade.
The new washer replaces existing washer 29804. The existing stud (P/N
127641) and nut (P/N 127567) are not affected by these changes and
will continue to be used.
SERVICE CARRIER NOTE:
With the popularity of Dana carriers inventory of both early design carriers
and new “Thick Flange” design carriers exist. If you have a vehicle that
was originally equipped with a Dana axle built with the “Thick Flange”
carrier design, it can be universally serviced with an early style (Thin
Flange) carrier unit. The repairing dealer must simply make sure to use
the correct axle housing hardware parts when installation is done. New
carriers built with the thick flange design, will include the necessary
thick flange hardware kit to minimize any down time to the customer.
• Differentials with “THICK FLANGE” carriers use axle housing
hardware kit (P/N 512087).
• Early design differentials with “THIN FLANGE” carriers use axle
housing hardware kit (P/N 511600).
New Axle Housing Fasteners
IMPORTANT!
Dana does not recommend the mixing of various designs carrier-to
housing capscrews on the same assembly. Whether mixing or not,
torques must be measured using a calibrated torque wrench. Failure to
re-torque bolts and nuts to proper specifications may lead to carrier to
housing leaks and possible component damage.
