Installation of the DD13 Exhaust Gas Recirculation Valve Actuator Pull
Rod
Install as follows:
NOTE: If installing a new style Exhaust Gas Recirculation (EGR) valve actuator pull rod, the end with the "V" is
attached at the EGR valve actuator and is facing away from the engine.
1. Install the EGR actuator valve pull rod on the EGR valve linkage stud and the EGR valve actuator linkage.
Table 3.
Older Style Pull Rod (Cast Aluminum )
Newer Style Pull Rod (Stamped Stainless Steel)
NOTICE: Ensure the nut used to attach the pull rod to the linkage has a 12mm hexagon pattern. A larger 13mm
hexagon pattern nut will cause damage to the pull rod bearing.
2. With the EGR valve actuator pull rod installed on the EGR valve and the EGR valve actuator, apply a small amount of
copper-based, anti-seize compound to the nut threads. Install and torque to 20 N·m (15 lb·ft).
3. Run the "EGR Actuator Slow Learn" procedure in DiagnosticLink™.
