1U-5470 Engine Pressure Group
Refer to Special Instruction, SEHS8907, "Using the 1U-5470 Engine Pressure Group" for the instructions that are needed to use the 1U-5470 Engine Pressure Group. Refer to Operation Manual, NEHS0818, "Using the 198-4240 Digital Pressure Indicator Group" for the instructions that are needed to use the 198-4240 Digital Pressure Indicator.
Check the air filter restriction indicator on the air inlet for a reading of the restriction.
Inspect the engine air cleaner inlet and ducting to ensure that the passageway is not blocked or collapsed.
Check for a buildup of dirt on the clean side of the engine air cleaner element, the air inlet hose, and the clamps. If a buildup of dirt is observed, check the condition of the following components:
Engine air cleaner element
Seal for the air cleaner
Air inlet hose
Inspect the engine air cleaner element. Replace a dirty engine air cleaner element with a clean 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 or the 198-4240 Digital Pressure Indicator.

Air inlet system (typical example)
(1) Turbocharger
(2) Air Inlet Piping
(3) Test location
(4) Air cleaner
Connect the vacuum port of the differential pressure gauge to test location (3). Test location (3) can be located anywhere along air inlet piping (2) after engine air cleaner (4) but before turbocharger (1).The air flow through the air cleaner element during full load operation must not have a system restriction of more than the following amount:Maximum restriction ... 3.7 kPa (15 inches of H2O)Exhaust Restriction
Exhaust restriction is measured between the exhaust at the outlet elbow and the atmospheric air pressure.In addition to the loss of efficiency and power, excessive exhaust restriction will lead to these results: high engine temperatures, reduced service life of the turbocharger and early problems with inlet and exhaust valves.Use the differential pressure gauge of the 1U-5470 Engine Pressure Group to measure the exhaust back pressure.
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 on the exhaust manifold. The test location may be located anywhere along the exhaust piping after the turbocharger but before the catalytic convertor. Choose a location that is as close to the engine as possible. Install the probe into a straight pipe that is three to five diameters of the pipe away from the last transition.For turbocharged engines, the maximum exhaust back pressure is 6.7 kPa (27 inches of H2O).If the exhaust restriction reaches this limit, determine the cause of the restriction and correct the condition.
