INSTALLATION
PILOT MOUNT CLUTCH-BRAKE
Refer to Figure 1.
NOTE
These are "hub-stop" clutch-brakes. They stop the shaft on
which they are mounted. Therefore, they must be mounted on
the driven shaft.
1. Secure a customer supplied sheave or sprocket to the Clutch-
Brake.
2. Insert the first Key (Item 30) into the shaft.
3. Slide the Clutch-Brake onto shaft and key; then, insert the
second Key (Item 30).
4. Tighten Set Screws (Items 27 and 28) to the recommended
torque (See Table 1).
NOTE
If a bushing for smaller diameter shafts is required, use a
bushing on both ends of the Clutch-Brake.
5. Align air inlet ports to a six o’clock down position to allow
condensation to drain out of exhaust port.
6. Fasten one of the ears of the Clutch-Brake to a fixed member
of the machine.
NOTE
The Piston Air Chamber (Item 7) floats axially approximately
1/16 inch [1.59 mm] during operation. Make sure securing
pin allows 1/16 inch to 1/8 inch [1.59 mm to 3.18 mm]
movement of Piston Air Chamber.
