Gate Rotor Float and Gate Rotor Bearing Float Inspection

GATE ROTOR FLOAT INSPECTION

To inspect gate rotor float and bearing float, proceed with the following steps:

1.Remove center member, see appropriate Drive Coupling Replacement procedure.

2.Remove the side covers from compressor.

3.Position gate rotor blade and damper pin at 90° to the main rotor, see Figure 5-13.
