Reviews

Did the job OK on my parallel valve 0 360 but it was difficult to start compressing the valve spring on reassembly. The curved piece that sits on and compresses the valve spring cap tends to push the cap off center from the valve stem making it difficult to center the cap on the valve stem. The angle seems too steep. On first contact the spring has to be compressed by hand to achieve alignment before fully compressing the cap to insert the Collets

This valve spring compressor does not work on an angled valve 0-470K in my Cessna 180. The geometry is wrong and the tool lugs are too short to compress the valve springs. I spoke to the tool manufacturer an they are looking at making an adapter for the 0-470 angled valve engines.
