 4. Procedure
_________ Subtask 12-14-32-614-055
 A. Aircraft on the Ground - Nitrogen Filling of the NLG Shock Absorber (Ref. Fig. 312/TASK 12-14-32-991-006)
 (1)
 Measure and record the shock absorber extension, dimension H.

 (2)
 Remove the blanking cap (1) from the charging valve (2). (Ref. Fig. 313/TASK 12-14-32-991-017)

 (3)
 Use a thermometer (-45 Deg.C to 70 Deg.C) to measure and record the temperature adjacent to the charging valve (2).

 (4)
 Install the FILLING ASSEMBLY (M21930) on the charging valve (2).

 (5)
 Install the standard charging equipment on the FILLING ASSEMBLY (M21930), as follows:

 (a)
 Connect the filling hose (12) to the FILLING ASSEMBLY. CAUTION : MAKE SURE THAT YOU USE A GAGE WITH THE SPECIFIED

_______ PRESSURE RANGE. THIS IS NECESSARY TO GET AN ACCURATE PRESSURE MEASUREMENT.

 (b)
 Install the pressure gage (11) on the 3-way valve (13).

 (c)
 Connect the 3-way valve (13) to the filling hose (12).

 (6)
 Make sure that the control valves (14) and (15) are closed.

 (7)
 Slowly open the charging valve (2) with the FILLING ASSEMBLY.

 (8)
 Read and record the pressure shown on the pressure gage.

 (9)
 Close the charging valve (2).

 (10)
 Use the recorded pressure and temperature values to identify the correct dimension H for the shock absorber extension. Compare this value with the dimension H you recorded in step (1). (Ref. Fig. 314/TASK 12-14-32-991-007)

 (11)
 No action is necessary if the value you recorded compares to dimension H plus or minus 5%.
