Description of Change: The new improved Aftertreatment Regeneration Device (ARD) combustion head now uses an improved seal at the pin base to help prevent foreign contamination into the ARD heating element. This new seal will greatly improve the reliability of the ARD combustion head. Refer to the illustrations below
Adaptable To: The new ARD 433-3675 Combustion Head Gp is a direct replacement for the present ARD 348-3400 Combustion Head Gp.
The new ARD 433-3677 Combustion Head Gp is a direct replacement for the present ARD 348-3402 Combustion Head Gp .
Both of the new ARD combustion heads are adaptable back to the first production of the engines in the above listed machines.
