FAQ

Q: How can I confirm this crankshaft will fit my engine?

A: Please verify your existing part number against our listed OEM numbers: YN25GB-03216-1 or SHAO3121. We recommend checking the physical dimensions, especially the main journal and connecting rod journal sizes, against your old component to ensure a perfect match. If you are unsure, please contact our support team with your engine model and serial number.

Q: What maintenance is recommended after installing a new crankshaft?

A: After installation, it is critical to perform a proper engine break-in procedure. Ensure all bearing surfaces are lubricated with clean engine oil before assembly. Check the main bearing and connecting rod bearing clearances using plastigauge to ensure they are within the manufacturer’s specifications. After initial startup, inspect the oil pressure and listen for any unusual noises. It is also recommended to change the engine oil and filter after the first 50 hours of operation.
