Engine Air Cleaner Differential Pressure - Check
Observe 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.
The nominal air filter differential pressure during normal engine operation is approximately
To avoid the derating of engine operation, replace the air filter element before reaching the maximum differential pressure of
For instructions on replacement of the air filter elements, see this Operation and Maintenance Manual, "Engine Air Cleaner Element - Replace" topic.
