FAQ

Q1: Is this bare engine a direct fit for my Caterpillar 320D excavator?
A: This S6K 320D bare engine is designed to OEM specifications for Caterpillar 320D series equipment. However, we recommend verifying your engine serial number and comparing mounting points (engine mounts, flywheel housing, and bellhousing pattern) to ensure compatibility. If you have any doubts, please contact our technical support team with your machine’s serial number for confirmation.

Q2: What is included with the bare engine, and what additional parts will I need?
A: The bare engine includes the complete engine block assembly with internal components (crankshaft, pistons, connecting rods, camshaft, and cylinder head). It does not include external accessories such as the fuel injection pump, turbocharger, alternator, starter motor, or cooling system components. You will need to transfer these parts from your existing engine or purchase them separately. We recommend replacing gaskets, seals, and filters during installation for optimal performance.

Q3: What maintenance is required after installing this engine?
A: After installation, perform an initial break-in period of 50 hours at varying loads (avoid sustained high RPM or full load). During this period, check oil levels daily and inspect for leaks. After the break-in, change the engine oil and filter, and check valve clearances. Follow the standard maintenance schedule for the Caterpillar 320D engine, including regular oil changes every 250 hours, fuel filter replacement every 500 hours, and coolant system checks every 1,000 hours. Always use high-quality diesel engine oil meeting API CI-4 or higher specifications.
