Section 5 • Maintenance/Service

For VSSG 291-601 compressors, do not use side rails.

For VSG 751/901 and

1051-1301compressors, use side rails and assemble gate rotor stabilizer as stamped.

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.

Use ﬂats provided on gate rotor support to prevent rotation when removing bearing retainer.

Position leading edge of main rotor groove ﬂush with or slightly below back of gate rotor support.
