Frequently Asked Questions

Q: Why is it recommended to replace the crankshaft and bearings together?
A: Crankshafts and main bearings wear in tandem. Installing a new crankshaft with old, potentially worn bearings can lead to premature crank failure and vibration, reducing engine efficiency and reliability.

Expert Pro-Tip: Always ensure your crankcase mating surfaces are perfectly clean before applying new gaskets. Use a high-quality assembly lube on all bearings and the cylinder bore during installation to ensure smooth initial startup and break-in.
