New Vent Tube For Water Cooled Turbocharger{1380,1052}
Usage:
3408 and 3412 Industrial Engines ( 67U, 38S)
Description of Change: A new vent tube is used to connect the water cooled turbocharger to the water regulator housing cover on 3408 and 3412 Industrial Engines. The position in which the new tube is installed gives more clearance between it and the turbocharger than the former tube. In the past, contact between these parts was a problem on engines equipped with Airesearch Turbochargers.
Adaptable As: A direct replacement as shown in the chart that follows:
