Heavy Equipment & Generators
Used Caterpillar 3516 Generator: Sell or Buy at Auction
Caterpillar is the world's largest manufacturer of construction and mining equipment, and a major producer of diesel and gas engines and industrial generators. Cat equipment is the most recognizable heavy equipment brand globally, with unmatched parts availability and dealer network creating extremely liquid used equipment markets.
The Caterpillar 3516 is a large-frame diesel generator set built on Cat's 3500-series engine: a V16, four-stroke design of roughly 69 liters (about 4,200 cubic inches) displacement, the 16-cylinder counterpart to the 12-cylinder 3512. Across its variants (3516, 3516B, 3516C, and the higher-output 3516E), the platform is commonly rated for standby output in the range of about 1,500 to 2,500 kW (roughly 1,875 to 3,125 kVA at 0.8 power factor), available for 60 Hz or 50 Hz service, with Cat digital voltage regulation, EMCP-series controls, and paralleling capability on many units. Depending on how a given set was specified, it may be an open skid-mounted unit or come in a weather-protective or sound-attenuated enclosure. Sets this size are purpose-built for prime, continuous, or emergency standby power at data centers, hospitals, mining operations, and oil and gas sites, so the buyer pool skews toward power generation users, rental fleets, and dealers rather than smaller contractors. Because the 3500 platform is a global standard with parts and dealer service on every continent, and because it can be configured for either grid frequency, large 3516 sets routinely draw international interest, particularly from operators in developing markets adding generating capacity. That demand, reached through KD Auctions' network of 500,000+ industry contacts, keeps large-frame Cat gensets like the 3516 moving quickly once they reach the block.

Frequently Asked Questions
What is a used Caterpillar 3516 generator worth, and how do I sell one at auction?
Value depends on the specifics: the model variant (3516, B, C, or E), age and run hours, standby versus prime or continuous rating, fuel and control configuration, enclosure type, voltage and frequency, and overall condition, so no single number fits every unit. KD Auctions starts with a free, AMEA-accredited and USPAP-compliant appraisal that documents both orderly liquidation value (OLV) and forced liquidation value (FLV), giving you a defensible range before you commit to a sale. From there, a managed auction typically runs 6 to 10 weeks from engagement to payout, with onsite dispatch to inspect and catalog the set within 48 to 72 hours. Commission is tailored to the engagement and quoted upfront, and most sellers pay nothing out of pocket.
How does the Caterpillar 3516 compare to a Cat 3512?
Both belong to Cat's 3500 series and share the same basic architecture, but the 3516 is the 16-cylinder engine while the 3512 has 12 cylinders, so the 3516 carries materially more displacement and produces a higher power class. In practice that pushes 3516 sets into the larger standby and continuous roles, such as sizable data centers, mining sites, and oil and gas installations, whereas the 3512 more often covers mid-range loads. The larger output and broad global parts and service support also tend to draw a bigger and more international pool of bidders for the 3516 than for the 3512.
