Do a leak test for the clearance control valve as follows (Fig. 402):
(a) Attach a pressure test hose to the drain outlet for the HPT
clearance control valve and right VSV actuator seal and shroud
with an adjustable hose clamp.
NOTE: The drain outlet for the HPT clearance control valve and____
right VSV actuator seal and shroud is found at the rear
drain assembly.
(b) Connect a dry air or nitrogen source to the hose fitting for
the pressure test.
(c) Apply a pressure of 20-25 psi (138-173 kPa) to the hose
fitting.
(d) Shut off the air or nitrogen supply when you have the correct
pressure.
(e) Monitor the pressure for two minutes.
NOTE: The pressure is permitted to decrease a maximum of____
10 psi (70 kPa).
(f) If the pressure decreases more than 10 psi (70 kPa), make sure
the fuel manifold bolts are tightened to the correct torque
value.
NOTE: This step applies if all connections between the____
junction plate and VSV actuator head and rod end shrouds
are not the source of the leakage.
