Improved Turbocharger Water Lines Group Eliminates Tube Cracking And Coolant Loss{1380,1052}
Usage:
3516 Locomotive Engines
Description of Change: The turbocharger water lines group is improved to provide an O-ring joint which will allow movement due to the expansion and contraction of parts. The water return circuit also has stronger tubes and connectors.
Adaptable To: The part number of the improve 7E1075 Turbocharger Water Lines Group did not change. The chart and illustrations identify the new components. The new components are direct replacements for the former components. The new components are effective with 3516 Locomotive Engine 9KF55.
