Information:
Introduction
Do not perform any procedure in this Special Instruction until you read this information and you understand this information.In a crankcase ventilation system, the fumes from the crankcase are filtered before the fumes are sent to the air intake system. Steps must be taken in order to prevent oil from collecting on the components of the air intake system. Otherwise, the following problems can result:
Decreased service life of air cleaner filters
Premature plugging of the aftercooler coreRecommendations
Route the fumes from the crankcase through a commercially available aftermarket fumes disposal system. Direct the filtered fumes to the dirty side of the air cleaner filter elements.Install soot filters on the air cleaner filter elements.Monitor the differential pressure of the air intake system in order to determine when the system requires servicing.Soot Filters
Soot filters fit firmly around 490 mm (19.3 inch) filter elements. Table 1 lists the part number and the height of the soot filters.

450 mm (18 inch) The soot filter can be cleaned in order to remove oil. Wash the filter in a solution of soap and water. Allow the filter to dry completely before installing the filter.Monitoring the Differential Pressure
A differential pressure gauge can be installed across the air side of the aftercooler core. The differential pressure provides an indication of the amount of plugging in the aftercooler core. The 152-2067 Oil Filter Pressure Differential Gauge Gp is suitable for monitoring the differential pressure. Table 2 lists the components and the locations for connecting the differential pressure gauge.
