|This cast aluminum alloy valve spring compressor fits Lycoming parallel valve and angle valve horizontally opposed engines. An excellent tool at an economical price.|
good tool but has broken after some uses !! alumium alloy bad
The tool comes with a sticker applied to the handle that says to be sure to break loose any stuck valve stem retainer's before using this tool. Mine were stuck and I didn't heed the warning on the tool. I broke the tool. The tool fits the Lycoming IO-360 engine perfectly and is very ergonomic but the tool is cast aluminum and won't hold up to much abuse.
