Installation Guide for Clutches, Brakes and Clutch/Brakes

1.) Apply a light coating of anti-seize compound (included) to mounting shaft.
Anti-seize compound allows for easy disassembly after an extended service life.

2.) Place key stock into mounting shaft keyway.

3.) Align unit keyway with that of mounting shaft keyway and gently slide unit on the mounting shaft.  Minimum shaft engagement for end mounted units should be no less than the unit shaft bore depth minus ¼ of an inch.

4.) If the unit is supplied with a drive, ensure that the unit drive is in-line with associated drive to avoid axial chain/belt pull.

5.) Tighten set screws of unit shaft after unit is in correct position.  Refer to torque values listed below for set screw tightening torque.

6.) Rotate the unit housing so the air inlet port hole is in the 6 o'clock position so air supply line moisture is not as likely to enter the unit housing.

7.) Attach torque arm to stationary piston housing to a fixed member using the anti-rotate holes, or secure the brake to a fixed member using the mounting holes.  Torque arms should be a non-rigid restraint in the form of a bracket, stopping peg, or strap. See example below.

8.) Attach air line fitting to air port hole of unit housing or rotary union taking care not to cross-thread.  Use a small amount of joint compound to help prevent possible leaks. 

9.) If the unit is supplied with a quick-disconnect rotary union, install the rotary union in the unit shaft and connect the plastic air supply line. Ensure that the air line does not bind the fitting.  WARNING - If the air line is pulling against the fitting in any direction other than the direction of rotation premature failure will occur.
