1U-5470 Engine Pressure Group
The 1U-5470 Engine Pressure Group has a gauge that measures the oil pressure in the engine. Refer to Special Instruction, SEHS8907 for more information on the 1U-5470 Engine Pressure Group. The information is included in the tool group.
Ensure that the engine is filled to the correct oil level.
Connect the 1U-5470 Engine Pressure Group to a pressure tap location for engine oil.
Operate the engine. Allow the engine to obtain normal operating temperature.
Keep the oil temperature constant with the engine at the rated rpm. Read the pressure gauge.
Refer to Table 2 in order to determine if the engine oil pressure is in tolerance.
Table 2
Oil Pressure(1)
Oil Pressure at high idle 196 to 441 kPa (28.4 to 64 psi)
Oil Pressure at low idle 49 kPa (7.1 psi) or more
(1) The oil temperature must be 80 ° C to 110 ° C (176 ° F to 230 ° F).Find the cause of the problem and correct the problem if the results of the test do not fall within the pressure range in Table 2. Engine failure or a reduction in engine life can be the result if engine operation is continued with oil pressure outside the range.Note: A record of engine oil pressure at regular intervals can be used as an indication of possible problems and damage of the engine. The engine should be inspected and the problem should be corrected if there is a sudden increase or a sudden decrease of 70 kPa (10 psi) in oil pressure.
