FAQ

1. Is this crankshaft a direct replacement for my Mitsubishi 4D34 engine?

Yes, this crankshaft (ME136680 / ME017354) is a direct-fit OEM replacement for the Mitsubishi 4D34 engine. It is machined to the same specifications as the original part and requires no modification for installation. However, we always recommend verifying your engine’s serial number and comparing it with the original part to ensure 100% compatibility.

2. What maintenance is recommended after installing a new crankshaft?

After installation, it is critical to use new main bearings, connecting rod bearings, and thrust washers. Ensure the crankshaft is properly lubricated during assembly. After initial startup, check oil pressure and listen for unusual noises. Follow the engine manufacturer’s break-in procedure, including an oil and filter change after the first 50 hours of operation.

3. How should I verify the part number before ordering?

You can verify the part number by locating the casting or stamping on your old crankshaft, or by checking your engine’s service manual. The OEM numbers ME136680 and ME017354 are the primary identifiers. If you have a different part number, please contact our sales team with your engine model and serial number for cross-referencing assistance.
