New Air Pipe Retainers Used To Connect Turbocharger To Aftercooler
Usage:
3306 Industrial, Generator Set Engines
Description of Change: New retainers are used to secure the air tube between the turbocharger and the aftercooler in the above models. See the illustration. The retainers have a yoke design which provides better retention of the air tube. Formerly, flat washers were used to secure this tube. It was possible for the washers to vibrate loose, causing loose connections at the turbocharger and aftercooler joints. This resulted in a loss of manifold boost pressure and possible leakage of unfiltered air into the air intake system.
Adaptable As: The new retainers and new bolt are direct replacements for the former washers and bolts as shown in the following chart.
