Aircraft engine crankcases must be separated to allow removal of the crankshaft, camshaft and other internal engine parts. Many Lycoming engines require special tools to push the crankcase halves apart. Until very recently MMS used a quickly improvised set of tools to do this. The old tools protected the engine parts from damage and undue stress, but were inefficient and had become quite worn. New factory-made tools for this operation are very expensive; however, the engine overhaul manual has pictures of the tools and a clear description of how they are used.
Several years ago money to purchase a milling machine was donated and MMS Director of Maintenance Tim Obarow is a skilled machinist. An adequate amount of heavy steel plate and some other material were purchased and Tim went to work. Using that milling machine and a lathe, Tim fabricated the various parts of the new tooling for the engine shop.
So, how did the new tooling work? To quote Dale, "Great!"
