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, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.

1U-5470 Engine Pressure Group
The 1U-5470 Engine Pressure Group measures the engine oil pressure in the system. This engine tool group can read the engine oil pressure inside the oil manifold.Note: Refer to Special Instruction, SEHS8907, "Using the 1U-5470 Engine Pressure Group" for more information on using the 1U-5470 Engine Pressure Group.

Location of the oil gallery plug
Typical example
(1) Plug
Install the 1U-5470 Engine Pressure Group into oil gallery plug (1). Note: Engine oil pressure to the camshaft and main bearings should be checked on each side of the cylinder block at oil gallery plug (1).
Start the engine. Run the engine with SAE 10W30 or SAE 15W40 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 engine oil pressure on the engine oil pressure graph.

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. The problem needs to be corrected. 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 engine oil pressure suddenly increases or decreases 70 kPa (10 psi) and the engine 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 engine oil pressure indicators on the instrument panel.
An engine oil pressure indicator that has a defect or an engine oil pressure sensor that has a defect can give a false indication of a low engine oil pressure or a high engine oil pressure. If there is a notable difference between the engine oil pressure readings make necessary repairs.
If the engine oil pressure is low, refer to Testing and Adjusting, "Engine Oil Pressure is Low" for the possible causes of low engine oil pressure.
If the engine oil pressure is high, refer to Testing and Adjusting, "Engine Oil Pressure is High" for the possible causes of high engine oil pressure.
