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.
