Overhauling a Weichai diesel engine demands precision, power, and the right toolkit. Whether you're servicing a WD618, WP10, or WD615.68 model, using the correct tools and parts is critical to restoring performance and ensuring long-term reliability. This guide outlines the most essential tools and components every technician should have for a successful overhaul—and how NBDN Tools supports professionals in doing the job right.
