show factory-
a. Disconnect the rod end bearings connecting the
inlet vane operator levers to the guide vane
links as in Figure 10, p. 22
Leave the rod end bearing connecting the guide
vane links to the main drive levers attached.
N N o o t t e 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
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
drive support assemblies to the compressor
castings and remove the main drive and inlet
vane levers from the compressor as a unit. See
