1-92
NOTE
If it is determined that foreign object
damage has occurred to inlet housing,
first stage insert, compressor blades, or
stator vane assemblies, a thorough in-
spection of compressor blades, stator
vane assemblies, centrifugal compressor,
and compressor housings must be
performed. If foreign object damage
is not evident, omit step 5.
5. Remove upper compressor housing (Ref. Task
2-19) and proceed as follows:
a. inspect compressor rotor blades (Ref. Task
2-33).
b. Inspect centrifugal impeller (Ref. Task
2-33).
c. Inspect compressor housing (Ref. Task 2-22).
d. Inspect stator vane assemblies (Ref. Task 2-28).
e. Check clearance between compressor housing
and first through seventh stage compressor
rotor blades as follows:
(1) Using thickness gage (5), check right and
left sides of compressor housing (6).
(2) Tip clearance shall not be less than 0.019
inch for all stages.
