(h) TORQUE the nut (50) to between 55 and 70 lbf.in (0.62 and 0.79 m.daN).
(i) Attach the actuator clevis, with the clevis link (90) installed, to the bellcrank assembly with the bolt (40), bushing (30), washer (20) and nut (10).
NOTE : Put the head of the bolt (40) outboard.
____
(j) TORQUE the nut (10) to between 55 and 70 lbf.in (0.62 and 0.79 m.daN).
R (k) Lubricate the new O-rings (140) with vaseline (Material No. CP5070) and install them on the head-end and the rod-end fuel tubes.
R (l) Lubricate the new O-rings (150) with vaseline (Material No. CP5070) and install them in the head-end and the rod-end drain shrouds.
(m) Connect the fuel tubes to the nipples (130) on the actuators at the head-end and the rod-end ports.
(n) TORQUE the fuel tube nuts to between 135 and 150 lbf.in (1.52 and
1.69 m.daN).
NOTE : Do not connect the head-end and the rod-end drain shrouds
____
at this time.
(o) For the right actuator, connect the actuator drain tube to the actuator drain port.
(p) TORQUE the drain tube nut to between 135 and 150 lbf.in (1.52 and
1.69 m.daN).
(q) Wirelock the actuator drain tube nut with lockwire 0.032 in. (0.8mm) dia. (Material No. CP8001) or lockwire 0.032 in. (0.8mm) dia. (Material No. CP8002).
(r) Remove the blanking cap and plug from the electrical connector.
(s) Connect the electrical connector. Tighten the coupling ring by
R hand plus one-eighth of a turn. If necessary, use soft-nose pliers.

B. Leak check of the VSV actuator
(1) Do a leak check of the actuator fuel tube connections as follows:
WARNING : DO NOT APPLY MORE THAN 300 PSI (20.7 BAR) TO AVOID DAMAGE
_______
TO THE ACTUATOR.
(a) Remove the blanking caps from the head-end and rod-end flex-hoses at the HMU.
(b) Install the reducers supplied with the CART - STATOR ACTUATOR (856A1084G04) to the rod-end and head-end flex-hoses at the HMU.
(c) Connect a source of dry air, regulated , nitrogen, or argon to the reducers.
(d) Apply the dry air, nitrogen, or argon to the head-end and the rod-end flex-hoses.
(e) Apply 250 +50 -50 psi (17.3 +3.45 -3.45 bar) to the head-end and rod-end flex-hoses.
(f) Apply leak-tek 160X (Material No. CP2170) to each fuel tube R connection at the VSV actuator. Then, make sure there are no R leaks. Look for leaks. No leaks are permitted.
(g) Stop the source of dry, regulated air, nitrogen or argon.
(h) Disconnect the head-end and rod-end flex-hoses at the HMU from the source of dry, regulated air, nitrogen, or argon. Then, remove the reducers from the ends of the head-end and rod-end flex-hoses at the HMU.
(i) Install the head-end flex-hose to the HMU. TORQUE the coupling nut to between 270 and 300 lbf.in (3.05 and 3.39 m.daN).
(j) Install the rod-end flex-hose to the HMU. TORQUE the coupling nut to between 180 and 200 lbf.in (2.03 and 2.26 m.daN).
(2) Connect the head-end and rod-end shrouds as follows:
(a) Connect the head-end and rod-end knurled connection nuts and tighten them by hand.
