PROBLEM
There have been isolated instances of the incorrect fan guard fasteners installed on certain C2.2 Industrial Engines. The existing fasteners are not retained when the guards are removed. When the guards are removed, the existing fasteners may become detached from the fan guard and may not be replaced. This may lead to the fan guards not being secure on the engine.
New fasteners are available that are retained on the fan guards.
