Canarm Ltd. uses pillow block bearings.
• Before removing the bearings mark the positions of the fan blade, bearings and pulley on the shaft.
• Note the clearance between the fan blade and the venturi.
• Remove the pulley and fan blade from the shaft using a puller.
• Unbolt the bearings and remove the shaft and pillow blocks as one unit.
• Clean the shaft and remove any marks using a file or emery cloth then remove the bearings using a bearing
puller.
• Inspect the shaft and replace if necessary.
• Mount the new bearings on a section of the shaft that is not worn by tapping the inner ring face using a soft
mallet.
• Align the setscrews on the bearings and then tighten one setscrew on each bearing.
• Loosely install the bearings on the bearing mount.
• Rotate the shaft to find the center of free movement.
• Install the propeller adjusting the bearing location to center the blade in the venturi.
• Tighten the bearing bolts to the proper torque rating
• Turn the propeller by hand the propeller should rotate freely with the same resistance as before the bearing
bolts were tightened.
• Tighten all setscrews to the proper torque rating
