Lycoming O-320-D2J is a four-cylinder, horizontally opposed, air-cooled, carbureted aircraft piston engine delivering 160 horsepower. This factory overhauled engine is supplied on an outright exchange basis, making it an excellent replacement for aircraft requiring dependable performance while eliminating the need to provide a rebuildable core.

The O-320-D2J is widely installed in general aviation aircraft, including selected Cessna 172 Skyhawk models. Its proven design provides smooth operation, reliable power output, and efficient fuel consumption, making it one of the most trusted piston engines in the aviation industry. The engine features a dynafocal mounting configuration and is engineered for long service life with straightforward maintenance procedures.

A factory-overhauled engine is disassembled, thoroughly inspected, repaired or replaced with serviceable components as required, and reassembled to meet the manufacturer's overhaul specifications. Critical rotating and reciprocating components are inspected for dimensional accuracy, while cylinders, crankshaft, camshaft, bearings, valve train, and accessory drive components are restored to ensure dependable operation and continued airworthiness.

This outright configuration is intended for operators who require an immediately available replacement engine without participating in a core exchange program. It is suitable for engine replacement following scheduled overhaul intervals, major maintenance events, or restoration projects where minimizing aircraft downtime is a priority.

Routine operation should follow the applicable Lycoming operating and maintenance manuals, including recommended break-in procedures, oil change intervals, inspections, and scheduled maintenance to maximize engine reliability and service life.
