Nitrogen Charging Procedure - Continued
N OT E
To ensure accumulator nitrogen charge is correct, accumulator piston must be at bottom of accumula-
tor cylinder. Nitrogen pressure varies with temperature. To obtain most accurate nitrogen charge, tem-
perature of accumulator should equal outside air temperature. However, temperature of accumulator
could be higher than outside air temperature in some cases. If this is case, temperature of accumulator
should be used instead of outside air temperature.
If nitrogen pressure appears on pressure gage in less time, close pressure regulating screw on regulator
assembly and disconnect hose assembly at coupling assembly next to pressure gage. Close needle valve
and remove coupling assembly. Repeat steps 6 thru 23. For correct nitrogen charge pressure, see
Table 1.
23.
Turn T handle (12) on nitrogen charging chuck (11) fully counterclockwise. Close regulator assembly (22) and needle
valve (14). Shut off nitrogen tank. Slowly disconnect hose assembly (17) from needle valve. Open needle valve.
Remove nitrogen charging chuck from nitrogen charging valve (8) on ride control accumulator.
24.
Install protective cap on nitrogen charging valve (8).
