Coupling Alignment with Sleeve Bearing Motors Caution: Complete the following procedures before attempting coupling alignment with sleeve bearing motors. Use a flange-type gear coupling for both 1800 and 2600 RPM motors. Do not use a sleeve-type coupling. Sleeve bearing motors have a specified end play. End play limits and the magnetic center (where motor will run) should be scribed on the shaft by the manufacturer. Use the following procedure to align a sleeve bearing motor with a blower. 1.
• Is the control panel energized? • Have maintenance and operations personnel been notified? CAUTION: This blower must have adequate system resistance at all times to avoid operation at or near free delivery (wide open). It Is typically imposed by the process and supplemented with a throttling valve. Running the blower overloaded will damage the motor. Start Up Caution: It is very important that the blower be installed with regard to the correct direction of rotation.
removal of the end head on the other. Removal of the end head provides immediate access to the impeller.
