The Caterpillar 3176 is a 7.2L inline-6 diesel, turbocharged, with a strong reputation in on-highway trucks, industrial equipment, and marine use. The live specs list about 230 to 300 hp and 600 to 900 lb-ft, with mechanical injection (the later 3176B went electronic) and 24V electrical. This is a used engine, inspected before it ships.
A practical note on fitment. The 3176 was a genuine on-highway truck engine, so the truck applications listed (Peterbilt 379, Kenworth W900) and the marine entries (Sea Ray 480, Hatteras 60) are plausible; the two industrial entries (Cat 325 excavator, 980G loader) should be confirmed, as those machines may use other Cat engines. Confirm the rating and application by the engine's serial number. This is a heavy freight item.

The 3176 was a real on-highway truck engine, so the Peterbilt and Kenworth entries are plausible, and the marine entries are reasonable. The two industrial entries (Cat 325, 980G) should be confirmed, as those machines may use other Cat engines. Confirm the rating and application by the engine's serial number. We disclose the donor details before shipping.
