 (b)
 Put the new packings (4) in position on the leakage-measurement solenoid valve 2150GP (5).

 (c)
 Put the new packings (4) in position on the leakage-measurement solenoid valve 3150GP (5).

 (6)
 Put the pilot valve (3) in position on the leakage-measurement solenoid valve (5).

 (7)
 Attach the pilot valve (3) with the two bolts (1), the washer (2) and the bonding tin (7) (Ref. TASK 20-28-00-912-004).

 (8)
 TORQUE the bolts (1) to 0.40 m.daN (35.39 lbf.in).

 (9)
 Safety the bolts (1) with lockwire, corrosion resistant steel dia 0.8mm (0.032 in.).

 (10)
