One size fits Continental and Lycoming. Tool is made of steel and will last long term use. If youre starting out in the business (A&P Mechanic) youll use this tool many times during your career.

Worked exactly as advertised! exactly the tool I needed to compress the valve springs on my Continental 0-200 cylinders.

Worked great on my C90! Perfect tool for removing the valve.

Used on a O-200. Works great!!

Perfect Continental Type Single Valve Spring Compressor. Very simple device that accomplishes a more complicated task to remove the valve springs while at the same time maintaining a closed valve. Often necessary to perform this task when removing a single stuck valve to burnish the stem and clear the valve guide of carbon buildup on a small Continental engine.

Does a good job of releasing and applying valve spring tension for valve removal/installation.

I’m not sure what the 1/2� steel rod was for. There was no way to use it on a TSIO 360. I bought a thin wall steel tube from Lowe’s and drilled two holes to attach it to the rocker bolts. That worked as the fulcrum for the tool.

Tool works perfectly

Great tool, it just did not fit the Continental O-520 valves we had. Solid construction and heavy duty steel.

Well built tool but only fits smaller cylinders. Compression forks do not extend far enough for larger bore cylinders. Did not fit my O-470-R. Description should add engine compatibility chart or usable distance range between rocker shaft center and valve center to help guide purchasers.

Does not work with Continental TSIO 360
