Usage:
1. Be sure that the engine is filled to the correct level with SAE 30 oil. If any other viscosity of oil is used, the information in the Chart For Engine Oil Pressure does not apply.
2. Find a location on the manifold to install a tee. Install a probe from the 8T470 Thermistor Thermometer Group in one side of the tee. Connect the 1U5470 Engine Pressure Group to the other side of the tee.
3. Run the engine to get the oil temperature at 93 ± 6°C (200 ± 10°F).
4. Maintain the constant oil temperature with the engine at 1200 rpm and read the pressure gauge.
If the results do not fall within the pressure range given in the chart, find the cause and correct it. Continued operation of the engine with oil manifold pressure outside this range may result in engine failure or reduction in engine life.
