(b) Connect the drain tubes to the shrouds. TORQUE to between 135 and 150 lbf.in (1.52 and 1.69 m.daN).
(c) Wirelock the head-end and rod-end knurled connection nuts with lockwire 0.032 in. (0.8mm) dia. (Material No. CP8001) or lockwire
0.032 in. (0.8mm) dia. (Material No. CP8002).
(3) Do a leak check of the head-end and rod-end drain shrouds as follows:
(a) Remove the blanking cap from the drain tube tap. NOTE : The drain tube tap is the first tap aft of the 6 o'clock
____ tube bundle junction box.
(b) Connect a source of dry, regulated air, nitrogen or argon to the tap.
(c) Apply between 20 psi (1.40 bar) and 25 psi (1.70 bar) to the drain tube.
(d) Stop the supply of dry, regulated air, nitrogen or argon.
(e) Monitor the pressure. The pressure cannot decrease more than 10 psi (0.70 bar) in 2 minutes.
R (f) If the pressure decreases more than the limit, apply leak-tek R 160X (Material No. CP2170) to all of the couplings on the drain manifold. Then, make sure there are no leaks.
(g) If you find leakage, make sure the coupling nuts are tightened to the correct torque. Or, tighten the knurled nut connections by hand until the leaks stop.
(h) If the leakage continues, remove and replace the O-rings in the area of the leak.
(i) Do the leak check again if you replaced an O-ring.
(j) Remove the source of dry, regulated air, nitrogen or argon.
(k) Install the blanking cap on the drain tube tap aft of the 6 o'clock tube bundle. TORQUE the blanking cap to between 135 and 150 lbf.in (1.52 and 1.69 m.daN).
