TESTING AND ADJUSTING MEASURING AND ADJUSTING LS DIFFERENTIAL PRESSURE Measuring with oil pressure gauge a Since the differential pressure is 1.96 MPa {20 kg/cm2} at maximum, measure it with the same oil pressure gauges. Applicable model: PC27, 30, 35MR-2 1. Remove oil pressure pickup plugs (1) and (2). PC27, 30MR-2 3. Run the engine at full throttle and measure the pump discharge pressure under the condition for measuring with the differential pressure gauge. a Read the gauge pointer accurately from the just front side of the gauge. 4. Run the engine at full throttle and measure the PC35MR-2 LS pressure under the condition for measuring with the differential pressure gauge. a Read the gauge pointer accurately from the just front side of the gauge. 5. Calculate the LS differential pressure from the pump discharge pressure and LS pressure. a LS differential pressure = Pump discharge pressure - LS pressure 2. Install nipple H2 and connect oil pressure gauge H1 (39.2 MPa {400 kg/cm2}) by
