COUPLING MOUNT
Refer to Figures 2 & 3.
1. Determine the parallel misalignment of the shafts to be
coupled.
NOTE: Before installation, the Driving Shaft can be fixed
but the Driven Shaft must be allowed to float.
a. Place a straight edge across the shafts and measure
the maximum offset of various points around the
outside of the shafts.
b. Make the necessary corrections to keep within the
parallel misalignment limits of the coupling (See
Table 3).
2. Attach the Adapter Plate (Item 24) to the Air Champ II,
using Cap Screws (Item 33) and Lock Washers (Item

INSTALLATION (continued)
10. Thread the screws supplied with the Dodge Taper-
Lock
®
bushing into the threaded holes of the Coupling
Hub (Item 26); then, alternately and evenly tighten the
screws to the bushing manufacturer’s specifications.
11. Align the pins in the Coupling Hub (Item 26) with the
holes in the Flexible Ring (Item 25) and push the entire
assembly together.
NOTE: Automatic spacing is accomplished by a spacer
molded into the Flexible Ring (Item 25).
12. Secure the Driven Shaft.
CALIPER DISC MOUNT
1. Air Champ II clutches have brake disc-mounting features
on the face of the drive disc or sheave. Select disc sizes
are offered for each of the four clutch models. The
combination of a disc, DB Caliper Brake / T-Bracket
and clutch create a clutch-disc-caliper brake.
2. Each disc comes with six flat head cap screws to
assemble the disc to the drive disc or sheave. Place the
disc on the larger pilot and secure with flat head cap
screws. Tighten cap screws with appropriate tightening
torque. It is recommended the disc run out be within
0.010 inch (0.25mm) or optimum performance.
