Follow the fan guard installation instructions to ensure that the fan guard(s) are properly installed.

BAC Maintenance Tip

If replacing only the top fans haft bearing on vertical shafts, the locking collar on the bottom fan shaft bearing must be loosened and then retightened after the installation of the new top bearing. This is critical because, by design, the top bearing is intended to handle the thrust load.
