FAQ

Q: Is this Overhaul Repair Set a direct fit for my Yanmar 4TNE94 engine?
A: This set is designed to be a direct replacement for the Yanmar 4TNE94 engine. However, due to minor production variations, we strongly recommend comparing the included components (pistons, rings, gaskets, bearings) with your original parts. Check your engine serial number and the original part numbers on your old components for 100% compatibility.

Q: What is included in this kit? Does it contain the crankshaft?
A: This kit includes the cylinder piston set (pistons, rings, pins, clips), full gasket set, main bearings, connecting rod bearings, oil seals, and valve/pump components as listed. While it includes the “crankshaft gasket kit” (seals and bearings), it does not include the crankshaft itself unless explicitly specified. Please review the product listing or contact us for a detailed component list.

Q: What is the recommended procedure after installing this overhaul kit?
A: After installation, a proper break-in procedure is essential. This includes:

1. Filling with the correct grade of engine oil and coolant.
2. Running the engine at low idle (1000-1200 RPM) for the first 30 minutes without load.
3. Checking for leaks, unusual noises, and proper oil pressure immediately after startup.
4. Avoiding full-load operation for the first 50 hours to allow rings to seat properly.

We recommend using a genuine Yanmar service manual for detailed torque values and procedures.
