The Lycoming engine case splitting tool can be used on both four and six-cylinder engines. It will also work on the older "Narrow-Deck" and the newer "Wide-Deck" engines. There are two additional plates that allow the engine to be separated without having a crankshaft installed.

See our article in the January 2014 edition of Kitplanes on using our tool.

The part number equivalents for this tool include:

ST-122 pressure plates,
ST-389 Crankcase Separating Tool, and
ST-389-1 Asymmetrical Crankcase Separating Tool.
