Figure 5-22. Gaterotor Assembly Removal
Use ats provided on
gaterotor support to
prevent rotation when
removing bearing
retainer.
This will push the thrust bearings onto the shaft
and push the housing assembly into the frame.
Install the inner retainer (115) and bolts (151) us-
ing Loctite® 242 thread locker. Tighten bolts, see
Appendix A.
19. Set clearance between gaterotor blade and shelf.
20. Place a piece of 0.003”-0.004” shim stock between
gaterotor blade and shelf.
NOTE
This measurement determines the amount of shims
needed for the correct clearance.
21. Measure depth from top of compressor case to top
of thrust bearing housing.
22. Use factory installed shim pack (106) and bearing
housing cover (116) without the O-ring (143).
NOTE
Replacement blades are precisely the same
dimensionally as blades installed originally at
factory: Therefore, the same amount of shims will
be required for replacement blades.
