8.4 Compressor Coupling
A flexible Dodge coupling is used to direct
couple the compressor to the motor shaft. To
properly assemble the C-Flange and coupling
onto the compressor, follow the installation
instructions for C-Flange and coupling supplied
with the C-Flange packages.
The required coupling for each different motor
size can be found in the following table. The
coupling dimensions can be found in the figure
below.

8.5 Overall Dimensions
All the 05T compressors have the same exter-
nal physical dimensions, therefore the variables
that will affect the overall dimensions of the
assembly are the motor and C-Flange. The
dimensional drawing shown in the 05T dimen-
sion drawing supplies the assembly dimen-
sions with the different C-Flanges and motors.
