e:: Do not rotate the rod end bearings on the

shaft as this will alter the inlet guide vane
operations and compressor performance.

b. Remove the cotter pin securing the vane

operator stud to the vane drive and slide the
stud out of the main drive. See

Figure 12, p. 23

.

c. Remove the hex head bolts securing the vane

drive support assemblies to the compressor
castings and remove the main drive and inlet
vane levers from the compressor as a unit. See

Figure 12, p. 23

.

d. Remove the hex head bolts securing the vane
