INSTALL HUB AND AIR SEAL

Hub installation instructions:

The aluminum bushing is lubricated and pre-installed in the hub at the factory, no further lubrication is required prior to installa­tion. DO NOT apply lubricant between the bushing bore and the shaft. Leave slight play between the bushing and hub to fa-
cilitate installation on the shaft. Place the hub/bushing on the shaft. Insert the key, and tighten the setscrew to secure the hub and
key to the shaft. Now begin sequentially tightening the socket head cap screws (approximately 2-3 turns per cap screw initially)
to firmly engage the bushing in the hub and seat the bushing on the shaft. Once the bushing/hub is firmly seated on the shaft,
continue tightening the cap screws sequentially until the specified torque of 50 FT-LBS (6.9 M-KG) is reached.
DO NOT over-tighten cap screws as this could cause damage to the hub.

Check to see that the hub is level. If the drive shaft is not truly vertical,
causing the hub to be cocked, it will be difficult to adjust blade angles
accurately. Eccentric rotation of the fan can also cause serious vibration
problems. If misalignment, vibration or unbalance in the system is present, it
will be more easily identified and corrected at this time.
