FLYWHEEL GP 7S7875 - Caterpillar

the air cleaner differential pressure frequently during engine operation. The air cleaner differential pressure is measured from the turbocharger air inlet. As the air filter element becomes plugged, the difference in pressure between the two sides of the air cleaner element will increase. To avoid the derating of the G3516H engine, replace the air filter element before reaching the maximum differential pressure of 2.5 kPa (10 inch of H2O). To avoid derating of the G3520H engine, replace the air filter element before reaching the maximum differential pressure of 3.6 kPa (14.46710 inch of H2O). For instructions on replacement of the air filter element, see this Operation and Maintenance Manual, "Engine Air Cleaner Element - Replace".
