These are service records documenting major preventive maintenance (PM) completed on five generator units belonging to Cold Regions Research and Engineering Laboratory in Hanover, New Hampshire. All work was entered on 8/11/2026, requested on 9/15/2026, and completed on 10/6/2026. The work was assigned to AFROST and classified as Low-Severity PM.

The records detail maintenance on five separate generator units: two ONAN units (Serial Numbers E950578362 with 566.4 engine hours and L32237M with 770.5 engine hours), two GENERAC units (Serial Numbers 3006710909 with 151.8 engine hours and 3006710910 with 403.8 engine hours), and one Caterpillar unit (Serial Number 2WB13709 with 2,606 engine hours). Parts replaced across all units included various oil filters, fuel filters, coolant filters, and conventional diesel oil in quantities ranging from 3 to 18 quarts per unit. Each PM checklist encompassed comprehensive inspections of battery systems, engine components, cooling systems, fuel systems, safety shutdowns, and operational controls, with all items documented as satisfactory or passing. No additional quotes or follow-up work was required.
