Used to easily remove valve guides from heated cylinder by injecting cool water. Prevents dragging aluminum with the guide when removed. For use on all Continental, Lycoming and Franklin cylinders.
Comes with driver with slide hammer and four inserts, water pump, hose and foot valve.
How it works: Heat/shrink type. Cylinder is heated to desired temperature. Low pressure water is applied to the tool which delivers it to the guide. Uses slide hammer action to tap the guide out if needed. Water reservoir not included.
