R (c) TORQUE the borescope plug to between 57 and 63 lbf.in (0.64 and 0.71 m.daN).
R R (d) Wirelock the borescope plug. Use Safetywire 0.032 in.(0.8 mm) dia. (Material No. CP8001) or Safetywire 0.032 in.(0.8 mm) dia. (Material No. CP8002).
(2) Install the stage 6, 7 and 8 borescope plugs (S6, S7 and S8) as follows:
CAUTION : MAKE SURE YOU FULLY SCREW THE INNER CAP IN. IF NOT FULLY_______ SCREWED IN, THE INNER CAP OF THE BORESCOPE PLUG WILL DEFLECT THE COMPRESSOR REAR CASE AS THE OUTER CAP IS TIGHTENED. THIS WILL CAUSE BINDING OF THE COMPRESSOR ROTOR.
(a) Make sure the borescope port is open. Insert 0.37 in. (9.40mm) diameter tapered Rod (locally purchased) in the borescope port.
R R (b) Apply graphite grease (Material No. CP2101) or Never seez-pure (Material No. CP2619) to the threads and pressure face of the borescope plug.
(c) Put the plug in the correct borescope port and tighten the inner plug by hand. Use the outer plug to turn the inner plug.
(d) Torque the inner plug to between 75 and 85 lbf.in (0.84 and 0.96 m.daN). Loosen half a turn and RETORQUE to between 15 and 20 lbf.in (0.16 and 0.22 m.daN).
(e) Compress the plug spring and tighten the outer plug by hand.
R R R R NOTE : If the inner plug is correctly installed and the threads____ are not damged, you can install the outer plug by hand. If the outer plug cannot be fully installed by hand , the inner plug is not correctly installed. Remove the plug and repeat steps (c), (d) and (e).
(f) TORQUE the outer plug to between 57 and 63 lbf.in (0.64 and 0.71 m.daN).
(g) Wirelock all 3 outer plugs together with Safetywire 0.032 in.(0.8 mm) dia. (Material No. CP8001) or Safetywire 0.032 in.(0.8 mm) dia. (Material No. CP8002).
