R (9) Put the panel (140) in its approximate position on the fan case and R the T/R adapter ring. Engage one seal (145) first, against one of the R panel edges, then engage the other seal (145) against the opposite R panel edge. Make sure that the seals (145) are correctly compressed R between the panel and the adjacent struts around the panel.
R NOTE : It is not easy to get access to some (panel) clock locations.
____ R External aid will possibly be necessary to install the seal R (145) correctly between the panel and the related struss.
R (10) Push and hold the panel (140) against the fan case and attach it loosely with the seven srews (130).
CAUTION : DO NOT EXCEED THE SPEED OF 200 RPM TO APPROACH ALL
_______ ACOUSTICAL PANEL SCREWS BY USING PNEUMATIC OR ELECTRICAL SCREW DRIVERS.
R NOTE : You must install the 3 longest screws (130) at the aft of the
____ R panel.
R (11) Measure the self locking nut torque of each nut when you start to R tighten the screw.
R CAUTION : DO NOT EXCEED THE SPEED OF 200 RPM TO APPROACH ALL
_______ R ACOUSTICAL PANEL SCREWS BY USING PNEUMATIC OR ELECTRICAL R SCREW DRIVERS.
R NOTE : When possible, start the torque with the screws in the center
____ R of the acoustical panels.
R NOTE : Make sure that the screws are not damaged, replace them if
____ R necessary.
R (a) If the self locking nut torque is less than 4.5 lbf.in (0.05 R m.daN) (Ref. TASK 72-23-00-400-043).
R (b) If the self locking nut torque is within 4.5 lbf.in (0.05 m.daN) R and 31 lbf (0.35 m.daN), TORQUE the screws to between 66 and 75 R lbf.in (0.74 and 0.84 m.daN)
R (c) If the self locking nut torque is more than 31 lbf.in (0.35 R m.daN) but less than 49 lbf.in (0.55 m.daN), TORQUE the screws at R the running torque value and add 44 lbf.in (0.5 m.daN).
