You know how hard it is to get at the springs on the push rod tubes… Now, you can compress them and remove the tube in under a minute. Just slip this tool onto the spring and crank the shaft counterclockwise (an air ratchet works great for this) to compress the spring, and then give everything a wiggle and out it comes. The entire assembly remains lock in place with the spring compressed so that you can replace the tube and spring just as effortlessly by reversing the above steps. It’s really that easy! This tool will pay for itself in one top end job. It’s a must-have tool when working on big bore Continentals. This tool will fit all production engines Lycoming, Continental, Franklin, and even most old radials. 1 lbs (0.5Kg) shipping weight.
