I just read the accumulator testing procedure again for the 15th time. I had made an assumption that fluid coming out of the N2 side of the accumulator would mean there is a ruptured diaphragm, however the N2 pressure is just below 12 bar. The accumulator is 2 liter, if the diaphragm ruptured there would be very little pressure when the accumulator filled with fluid. I think the entire RAS is around 6 liters of hydraulic fluid. That is why the MCI manual says "If the pressure reading is less than 20psi, replace the accumulator." When testing the accumulator, Newell says it is normal to have some fluid come out. I was told to charge the hydraulic side to 250 PSI.
