SHOE-TRACK 2352504 - Caterpillar

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.

Maximum Differential Pressure and Service Procedures    
Component    Maximum Differential Pressure    Service Procedure    
Aftercooler Core    
7.5 kPa (30 inches of H2O)     Clean the aftercooler core.    
Air Cleaner Filter    
6.2 kPa (25 inches of H2O)     Clean the soot filter.
Replace the air cleaner filter, if necessary.    
Crankcase     The crankcase pressure must be within
0.5 kPa (2 inch of H2O) of the barometric pressure.     Service the crankcase ventilator filter.
Service the crankcase ventilation system, if necessary.
