PAD-BRAKE 1512628 - Caterpillar

All steps of this procedure must be followed for the pressure findings to be usable. 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. The easiest method is to remove the sending unit for the present gauge and install a tee at this location. Install a probe from the 9S9102 Thermistor Thermometer Group in one side of the tee. Connect a 8M2744 Gauge from the 5P6225 Hydraulic Test Box to the other side of the tee.3. Run the engine to get the oil temperature at 200 10°F (93 6°C).4. Maintain the constant oil temperature with the engine at the rated rpm from the chart 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 engine with oil manifold pressure outside this range may result in engine failure or reduction in engine life. Each oil pump may have different spring and washer arrangements, and there are different oil pumps. Make reference to OIL PUMP specifications for location of the correct spring and washer arrangement to get the maximum output for a specific oil pump.
