Overhauling your diesel engine returns it to a "like-new" condition. After a full disassembly, the engine's parts are inspected, cleaned, repaired, or replaced depending on their level of wear. Then, we test for performance and ensure the engine is running like it did when it came off the factory floor.
A commercial overhaul is one of the most cost efficient ways to get your engine back to running at full capacity. Compared to purchasing new and even used engines, there are considerable cost savings and often an engine overhaul. Often, an overhaul will offer better performance than what you'll get with a brand new engine.
