Watch a comprehensive 56-minute workshop video documenting the complete overhaul of a track rod from a Hitachi EH4000 mining dump truck. Follow the step-by-step restoration process as Cutting Edge Engineering Australia transforms a heavily worn component back to service-ready condition. Begin with dustless sandblasting using a RapidBlast SD140 system to strip old paint and expose the base material, then observe NDT magnetic particle crack testing to verify structural integrity before machining begins. Learn about line boring techniques using a Sir Meccanica WS2 portable unit to restore oval, out-of-specification pin bores back to round, followed by bore welding to rebuild material and precision machining to proper dimensions. Discover troubleshooting methods for unexpected challenges including broken bolt extraction and removal of old welded-in nuts, while witnessing repair welding and grinding of hammered and misshapen areas. Observe the final finishing processes including bore completion, face and chamfer cleanup, surface preparation, and repainting that complete the transformation from worn mining component to service-ready part.
