This valve spring tool comes to us from Ulf and Jörgen Leanders of Alfta Sweden. Being multiple time Top Alcohol Funny Car European Champions they understand the critical need to maintain the valve train in their BAE powered race car and found a real need to check and replace valve springs within the 75 minute rule. This is the device Jörgen designed to allow the quick and safe removal of springs between rounds. Four rocker stand attaching nuts on each head, replace the four twelve point mounting nuts and remain on the car. These nuts are the mounting hardware for the spring tool. After a run you remove the valve cover and, in a matter of 30 seconds you install the tool assembly. Rotate the engine to allow the valve to seat, insert the pressure gauge. Add pressure to the spring using the load screw until the valve just moves. This will show the seat pressure of the spring. If replacement is required, you simply replace the gauge with the compression tool and remove the spring. Turn the load bar over and check the second spring on the same cylinder. Move to the next cylinder and repeat the process. Switch sides and check the other head. You can check all sixteen valve springs on a Top Alcohol, Pro-Mod or Injected Fuel engine in less than ten minutes.
