Step 3: While holding the stirrer shaft, slide the mechanical seal stir 

bearing over the end of the shaft (a small amount of mineral oil can 

be applied to the stirrer shaft to help), through the bottom of the 

bearing. Once the bearing is installed in the center neck, continue to 

pull the shaft through the bearing and adjust to proper height. 

Please note: The stirrer shaft should be passed thru the bearing 

spindle approximately 2” past the final installation position (towards 

the motor) and then pushed downward to ensure the face seals 

remain in contact with each other.
