1U-5470 Engine Pressure Group
Air Inlet Restriction
There will be a reduction in the performance of the engine if there is a restriction in the air inlet system.
Inspect the engine air cleaner inlet and ducting in order to ensure that the passageway is not blocked or collapsed.
Inspect the engine air cleaner element. Replace a dirty engine air cleaner element with a clean engine air cleaner element.
Check for dirt contamination on the clean side of the engine air cleaner element. If any dirt contamination is observed, contaminants are flowing past the engine air cleaner element and/or the seal for the engine air cleaner element.
Hot engine components can cause injury from burns. Before performing maintenance on the engine, allow the engine and the components to cool.
Making contact with a running engine can cause burns from hot parts and can cause injury from rotating parts.When working on an engine that is running, avoid contact with hot parts and rotating parts.
Use the differential pressure gauge of the 1U-5470 Engine Pressure Group.
Connect the vacuum port of the differential pressure gauge to the test location. The test location may be located anywhere along the air inlet piping after the air cleaner but before the turbocharger.
Leave the pressure port of the differential pressure gauge open to the atmosphere.
Start the engine. Run the engine in the no-load condition at high idle.
Record the value.
Multiply the value from Step 4.d by 1.8.
Compare the result from Step 4.e to the appropriate values that follow. The air flow through a used engine air cleaner may have a restriction. The air flow through a plugged engine air cleaner will be restricted to some magnitude. In either case, the restriction must not be more than the following amount: Maximum restriction ... 7.6 kPa (30.54 inch of H2O)The air flow through a new engine air cleaner element must not have a restriction of more than the following amount: Maximum restriction ... 3.7 kPa (14.87 inch of H2O)Exhaust Restriction
There will be a reduction in the performance of the engine if there is a restriction in the exhaust system.Back pressure is the difference in the pressure between the exhaust at the outlet elbow and the atmospheric air.
Hot engine components can cause injury from burns. Before performing maintenance on the engine, allow the engine and the components to cool.
Making contact with a running engine can cause burns from hot parts and can cause injury from rotating parts.When working on an engine that is running, avoid contact with hot parts and rotating parts.
Connect the pressure port of the differential pressure gauge to the test location. The test location can be located anywhere along the exhaust piping after the turbocharger but before the muffler.
Leave the vacuum port of the differential pressure gauge open to the atmosphere.
Start the engine. Run the engine in the no-load condition at high idle.
Record the value.
Multiply the value from Step 4 by 1.8.
Compare the result from Step 5 to the value that follows. Back pressure from the exhaust must not be more than the following amount: Maximum back pressure ... 15 kPa (60.28 inch of H2O)
