Usage:
Problem:
During some operating conditions moisture can collect at the bottom of the airside of the aftercooler core. If enough moisture collects, it could be drawn into the engine and damage could result. Condensate drains are available to automatically drain the collected moisture from the aftercooler housing. If the incorrect aftercooler drain line group is installed on an engine, the moisture may not be completely drained from the aftercooler housing.
Solution:
Two different aftercooler drain line groups are available. The 134-3458 Drain Lines Group should be used in applications where the rear of the engine is lower than the front. Illustration 1 shows the 134-3458 Drain Lines Group. The 134-3459 Drain Lines Group should be used in applications where the front of the engine is lower than the rear. Illustration 2 shows the 134-3459 Drain Lines Group.
When servicing these engines, technicians should check to be sure that the correct drain lines group is installed for the engine's orientation.
