A valve stem support assembly is provided to prevent excessive loads on valves caused by very long heavy valve stem extensions. The support assembly includes a support casing surrounding the valve stem extension. A support bracket is rigidly mounted to the casing and extends into proximity with the valve stem extension. A bushing is engaged by the bracket and substantially surrounds the valve stem extension. A support collar is rigidly mounted to the valve stem extension and is disposed in supporting relationship to the bushing and the bracket. The weight of the elongated valve stem extension is transmitted to the bracket through the collar and the bushing to avoid excessive loads on the valve.
