(2)
If the pressure is more than the correct pressure "P" or if the pressure is between "P" and "P"- 15 bars (218 psi):
(a) Adjust the pressure as necessary (Ref. TASK 12-14-32-614-002).
(3)
If the pressure is more than 15 bars (218 psi) less than the correct pressure "P":
(a)
Do a leak check with SPECIAL MATERIALS (Material No. 05-004) on the gas manifold of the accumulator.
(b)
If you find leaks, try to stop them. Then pressurize the accumulator (Ref. TASK 12-14-32-614-002).
(c)
If you do not find leaks or if you cannot stop the leaks, replace the accumulator (Ref. TASK 32-44-11-000-001) and (Ref. TASK 32-44-11-400-001).
(d)
If the accumulator is replaced, bleed the Yellow hydraulic system (Ref. TASK 29-00-00-870-007) downstream of the engine pump, to remove nitrogen that can be in the hydraulic system (that the accumulator has caused).

A. Check of the Nitrogen Fill Pressure
(1) Refer to the accumulator pressure gage 2585GM on the brake Yellow-pressure accumulator. Make sure that the fill pressure is as follows:
-------------------------------------------------------------------------------| deg. C | deg. F | bar | PSI | -------------------------------------------------------------------------------| -20 | -4 | 61 | 885 | | -10 | +14 | 63 | 914 | | 0 | +32 | 65 | 943 | | +10 | +50 | 68 | 986 | | +20 | +68 | 70 | 1015 | | +30 | +86 | 72 | 1044 | | +40 | +104 | 75 | 1088 | | +50 | +122 | 77 | 1117 | | +60 | +140 | 80 | 1160 | -------------------------------------------------------------------------------
(2)
If the pressure is high or not more than 15 bars (218 psi) less than the correct pressure:
(a) Adjust the pressure as necessary (Ref. TASK 12-14-32-614-002).
(3)
If the pressure is more than 15 bars (218 psi) less than the correct pressure:
(a)
Do a leak check with SPECIAL MATERIALS (Material No. 05-004) on the gas manifold of the accumulator.
(b)
If you find leaks, try to stop them. Then pressurize the
accumulator (Ref. TASK 12-14-32-614-002).
(c)
If you do not find leaks or if you cannot stop the leaks, replace the accumulator (Ref. TASK 32-44-11-000-001) and (Ref. TASK 32-44-11-400-001).
