Systems Operation, Testing and Adjusting, RENR4608 (9EP9607), "R1300 L.H.D. Braking System", "Transmission Neutralizer Pressure Test"The information in Step 7 on page 46 for the pressure test for the transmission neutralizer has been revised. The revised information follows.
While the engine is running and the oil for the accumulator is at full pressure, depress the brake pedal on the left hand side until the pressure on the gauge reads 1035 140 kPa (150 20 psi). At this pressure, the ohmmeter should now indicate an open circuit condition. An audible "click" should be heard. The "click" indicates that the switch has been actuated.
