6) ENGINES WITHOUT PHASE 3 CHANGES; Install the bolt (30) and nut (25) that attaches the tube clamps (31) to the bracket (24).
7) ENGINES WITH PHASE 3 CHANGES; Install the bolt (30) and nut (25) that attaches the tube clamp (31) to the bracket (24).
8) Tighten the bolts (29 and 30) to 36-40 pound-inches
(4.1-4.5 newton-meters).
9) Install the bolt (40), washer (41), and nut (42) that
attaches the strut drain clamp (39) to the bracket (24).
a) Tighten the bolt (40).
(e) For the left TVBCA valve (5), do the steps that follow: 1) Lubricate the threads of the bolts (18) with engine oil. 2) Install the bolts (18) and nut (15) which attach the tube
clamp (17) to the bracket (19) found on the TVBCA valve flange. a) Tighten the bolts (18) to 36-40 pound-inches (4.1-4.5
newton-meters).
(f) Connect the turbine-vane cooling-air duct (8) to the TVBCA valve (5) with the steps that follow: 1) Put the new gasket (9) between the flange of the
turbine-vane cooling-air duct and the TVBCA valve flange. 2) Lubricate the threads of the bolts (7) with engine oil. 3) Attach the duct flange, and bracket (33) for the right
TVBCA valve (5), to the TVBCA valve flange with the bolts (7). a) Tighten the bolts (7), from one corner to the opposite
corner, to 85-95 pound-inches (9.6-10.7 newton-meters). b) Without loosening, tighten the bolts (7) again until the necessary torque is kept.
(g) Connect the turbine-blade cooling-air duct (3) to the TVBCA valve (5) with the steps that follow: 1) Put the new gaskets (1), with the metering plate (4) or the
ring spacer (4A) between them, in the flange of the cooling-air duct (3). a) Attach the gaskets (1) and the metering plate (4) or
the ring spacer (4A) with paraffin wax. 2) Lubricate the threads of the bolts (2) with engine oil. 3) Attach the duct flange, with the bracket (32) for the right
TVBCA valve (5), to the TVBCA valve flange with the bolts (2). a) Tighten the bolts (2), from one corner to the opposite
corner, to 85-95 pound-inches (9.6-10.7 newton-meters).
