Safety Requirements
NONEProcedure
Refer to Figure, requirements.
Grinding is permitted.
Use IAE 3P16273 Grind fixture 1 off or equivalent.
NOTE
All dimensions apply when Surface G is flat by 0.002in. (0.051 mm) and the 14.064 to 14.066in. (357.23 to 357.28 mm) Radius A is in the limits given in a free or held condition. Hold the segment on Surfaces B and G and Radius A.
Set-up and machine Surface B and hold to the maximum dimension.
SUBTASK 72-45-22-320-051 Machine the Front Face of the Replacement Duct Support Segment
Refer to Figure, requirements.
Do a dimensional inspection on the 0.144 to 0.146 in. (3.658 to 3.708 mm) dimension.
SUBTASK 72-45-22-220-057 Examine the Repair Area before Coating
Refer to Figure, requirements.
Mask all the areas not to be coated.
Use CoMat 02-047 TAPE, HEAT REFLECTIVE, CoMat 02-048 TAPE, HEAT REFLECTIVE, CoMat 02-049 TAPE, HEAT REFLECTIVE, CoMat 02-051 HIGH TEMPERATURE GLASS CLOTH TAPE, CoMat 02-052 HIGH TEMPERATURE GLASS CLOTH TAPE or CoMat 02-053 HIGH TEMPERATURE GLASS CLOTH TAPE.
