WARNING
WHEN YOU USE CoMat 01-076 METHYL ETHYL KETONE YOU MUST MAKE SURE THERE IS SUFFICIENT VENTILATION. YOU MUST USE THE CORRECT PROTECTIVE CLOTHING. YOU MUST NOT SMOKE. DO NOT PUT THE SOLVENT NEAR A SOURCE OF HEAT.THE MATERIALS USED IN THE COMPOUND ARE FLAMMABLE AND TOXIC. DO NOT BREATHE THE VAPORS GIVEN OFF. YOU MUST PUT ON GLOVES WHEN YOU MIX AND USE THE COMPOUND.
CAUTION
YOU MUST USE CARE WHEN YOU USE CoMat 01-076 METHYL ETHYL KETONE AS IT CAN CAUSE DAMAGE TO THE SURFACE PROTECTION. REFER TO TASK 70-38-21-380-501 TO REPAIR THE SURFACE PROTECTION.Mix a sufficient quantity of CoMat 08-029 PRIMER BASE, CoMat 07-067 PRIMER CONVERTER and CoMat 07-066 THINNER in a ratio of one part each by volume of the primer base/curing solution and one tenth by volume of the thinner.
Clean the mating surfaces of the open latch indicator and the bolts/washers with CoMat 01-076 METHYL ETHYL KETONE. Use a clean cloth made moist with the solvent. Dry the mating surfaces with a clean dry cloth.
Apply a thin layer of the compound to the surfaces of the four bolt head washer faces and the two washers FORWARD OPEN LATCH INDICATOR-THRUST REVERSER (71-00-23, 01-020), FORWARD OPEN LATCH INDICATOR-THRUST REVERSER (71-00-23, 01-030) and Fan Frame Assembly And Related Parts (72-32-03, 02-130).
Apply the dissimilar metal protection compound.
Attach the open latch indicator and the two shims FORWARD OPEN LATCH INDICATOR-THRUST REVERSER (71-00-23, 01-010) and FORWARD OPEN LATCH INDICATOR-THRUST REVERSER (71-00-23, 01-040) to the No. 6 strut fairing panel Fan Frame Assembly And Related Parts (72-32-03, 02-100) with the two bolts and the two washers FORWARD OPEN LATCH INDICATOR-THRUST REVERSER (71-00-23, 01-020) and FORWARD OPEN LATCH INDICATOR-THRUST REVERSER (71-00-23, 01-030) (at the top position). Do this while the bolts and washers are wet with the compound.
Install the two bolts, the two washers and the two nuts Fan Frame Assembly And Related Parts (72-32-03, 02-130), Fan Frame Assembly And Related Parts (72-32-03, 02-120) and Fan Frame Assembly And Related Parts (72-32-03, 02-110) to attach the open latch indicator, the two shims and the No. 6 strut fairing panel to the panel support bracket on the LP compressor intermediate case. Do this while the two bolts are wet with the compound.
Torque the two bolts FORWARD OPEN LATCH INDICATOR-THRUST REVERSER (71-00-23, 01-020) and the two nuts Fan Frame Assembly And Related Parts (72-32-03, 02-110) to 85 to 105 lbf.in (10 to 12 Nm).
Remove the unwanted compound from the adjacent surfaces with a clean cloth made moist with CoMat 01-076 METHYL ETHYL KETONE. Try to keep a small ring of the compound around the bolt head.
Install the open latch indicator.
