Cummins QSC 8.3 Engine Top-End Rebuild (Cylinder #1)

The contract requires a comprehensive top-end and cylinder rebuild of the number one cylinder on two Cummins QSC 8.3 marine diesel engines, encompassing full disassembly, detailed inspection, replacement of all worn or degraded components, and precise reassembly to meet original equipment manufacturer specifications. The work must ensure the engines are restored to optimal performance and reliability standards, with strict adherence to OEM guidelines throughout the process. The rebuild is focused exclusively on cylinder number one of each engine, but the scope demands a complete and thorough overhaul of that cylinder’s internal components including pistons, rings, valves, bearings, and associated hardware. The solicitation is issued as a subcontract under a Total Small Business Set-Aside, meaning only certified small businesses are eligible to compete, and the NAICS code 811112 classifies the effort as engine repair and maintenance services. The opportunity was posted on May 7, 2026, with responses due no later than 6:00 PM Eastern Time on May 17, 2026. Performance is required at Ilwaco, Washington, with a zip code of 98624, under the oversight of the Department of Homeland Security’s Sflc Procurement Branch 3. All work must be completed in compliance with federal acquisition regulations, and the successful vendor will be expected to deliver proven readiness and documented quality assurance for the restored engines.
