Equipment overview

One enclosed 2003 Caterpillar G3516C generator from the Ocala equipment group. The supplied generator-set nameplate identifies model 3516 and rates the set at 865 kW / 1,081 kVA, 0.8 power factor, 480 V wye, 1,300 A, 60 Hz and 1,200 rpm. The plate marks continuous duty without fan, three phase, six wire, series connection. These are nameplate values, not a present-condition test or a guarantee of net usable site output.

The maintenance sheet records an in-frame overhaul on October 18, 2021 at 44,485 hours. Recorded work includes remanufactured heads and cylinder packs, new rod bearings, remanufactured turbos and turbo bypass, exhaust work, rockers, bridges, pushrods, spark plugs and other service items. The January 10, 2023 closing entry is 46,156 hours, or 1,671 additional logged hours. These are dated records, not current meter readings.

Earlier records describe heavy siloxane buildup and moderate lacquering in 2015, and cylinder-12 piston-skirt scuffing plus small corrosion blemishes on crank journals during the 2017 in-frame work. These are historical observations. The later overhaul record does not substitute for inspection, current oil analysis, borescope findings or an operating test.

The additional nameplate photograph in the September 2026 equipment catalog resolves the earlier electrical-rating gap. The deck links the engine identity to the maintenance record; serials and exact site details remain available privately for qualified review. Inspect the installed engine and alternator, operating condition, protection, emissions configuration and application requirements before purchase. Landfill-gas service history does not establish a new natural-gas output rating.

A separate shared spare-parts list exists. Allocation, quantity on hand, condition and inclusion in a sale require agreement. Request the unit-specific inspection scope, included auxiliaries and release schedule.
