Work carefully around an engine that is running. Engine parts that are hot, or parts that are moving, can cause personal injury.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.

1U-5470 Engine Pressure Group
The 1U-5470 Engine Pressure Group measures the oil pressure in the system. This engine tool group can read the oil pressure inside the oil manifold.Note: Refer to Special Instruction, SEHS8907, "Using the 1U-5470 Engine Pressure Group" for more information on the 1U-5470 Engine Pressure Group.Note: Caterpillar Electronic Technician (ET) can be used to measure engine oil pressure. Refer to Troubleshooting for information on the use of Cat ET.

Pressure test location
Install the 1U-5470 Engine Pressure Group at the pressure test location.
Start the engine. Run the engine with SAE30 or SAE40 oil. The information in the engine oil pressure graph is invalid for other oil viscosities. Refer to Operation and Maintenance Manual, "Engine Oil" for the recommendations of engine oil. Note: Allow the engine to reach operating temperature before you perform the pressure test.Note: The engine oil temperature should not exceed 115°C (239°F).
Record the value of the engine oil pressure when the engine has reached operating temperature.
Locate the point that intersects the lines for the engine rpm and for the oil pressure on the engine oil pressure graph.

The results must fall within the “ACCEPTABLE” range on the chart. A problem exists when the results fall within the “NOT ACCEPTABLE” range on the chart. Correct the problem. Engine failure or a reduction in engine life can be the result if engine operation is continued with oil manifold pressure outside this range. Note: A record of engine oil pressure can be used as an indication of possible engine problems or damage. A possible problem could exist if the oil pressure suddenly increases or decreases 70 kPa (10 psi) and the oil pressure is in the “ACCEPTABLE” range. The engine should be inspected and the problem should be corrected.
Compare the recorded engine oil pressure with the oil pressure indicators on the instrument panel and the engine oil pressure that is displayed on Cat ET.
An engine oil pressure indicator or an engine oil pressure sensor that has a defect can give a false indication of incorrect oil pressure. If there is a notable difference between the engine oil pressure readings, perform the necessary repairs.
If low engine oil pressure is determined, refer to "Reasons for Low Engine Oil Pressure".
If high engine oil pressure is determined, refer to "Reason for High Engine Oil Pressure". Reasons for Low Engine Oil Pressure

Engine oil level is low. Refer to Step 1.
Engine oil is contaminated. Refer to Step 2.
The engine oil bypass valves are open. Refer to Step 3.
The engine lubrication system is open. Refer to Step 4.
The oil suction tube has a leak or a restricted inlet screen. Refer to Step 5.
The engine oil pump is faulty. Refer to Step 6.
Engine Bearings have excessive clearance. Refer to Step 7.
Check the engine oil level in the crankcase. The oil level can possibly be too far below the oil pump supply tube. The oil pump will not supply enough lubrication to the engine components. If the engine oil level is low, add engine oil in order to obtain the correct engine oil level. Refer to Operation and Maintenance Manual, "Engine Oil" for the recommendations of engine oil.
