UNSPSC 26101504: Diesel engines

UNSPSC 26101504 Diesel engines is a Commodity code that covers diesel-powered equipment repair, maintenance, and component services for standby power generation and fleet operations. State and local governments procure these services primarily for preventative and emergency maintenance of backup generators, load bank testing, diesel engine repairs for transit bus fleets, and component-level repairs on Cummins and Onan diesel powerplants. Recent solicitations show a mix of facility-based standby generator maintenance contracts and fleet-level diesel engine and chassis repair services for transportation authorities. Issuing bodies include state procurement offices, county utility authorities, transit departments, and municipal facilities managers. Service scopes typically include quarterly and annual preventative maintenance, fluid sampling and analysis, emergency callout response with guaranteed callback windows, parts and labor supply, and factory-certified technician deployment. Multi-year service contracts with firm pricing, 24/7 emergency response requirements with sub-two-hour callback windows, and comprehensive insurance and bonding requirements are standard across recent opportunities.

Recent activity spans Utah, Georgia, and Florida. The State of Utah Division of Purchasing (on behalf of the Utah Division of Technology Services) posted an IFB on July 16, 2026, for five-year diesel mechanic services to perform preventative maintenance on an Onan 900DFJC V12 diesel generator in Richfield, Utah, due July 31, 2026, covering quarterly inspections, annual comprehensive service, load bank testing, and 24/7 emergency repair coverage with 30-minute callback response. Broward County Transportation Department solicited on May 8, 2026, for open-end repair and rebuild services on Cummins engines and chassis systems for its bus fleet across multiple facility locations, with 24-hour business-hours response requirements and three-day chassis repair completion windows. The City of Dallas issued a solicitation on April 16, 2026, for a three-year ID/IQ emergency generator maintenance and repair contract covering standby generators across multiple manufacturers (Kohler, Cummins/Onan, Generac, Caterpillar), with 24/7 emergency service, 48-hour scheduled maintenance notice, and load bank testing, closing May 15, 2026. Activity also appears in Georgia with utility-focused motor and generator repair contracts, though those records show less direct diesel engine alignment than the power generation and fleet-focused opportunities in Utah, Florida, and Texas.
