Engine Machining & Rebuilding in Greenville, OH

At Koenig Equipment in Greenville, OH, our machine shop handles engine work from start to finish, beginning with a full teardown and thorough cleaning so we can see exactly what condition your engine is in before any machining begins. From there our technicians handle precision boring, honing, grinding and align boring to spec, then reassemble the engine in a clean room so it goes back to work the way you and your Customers expect.
