Important Note
- Engine bearings should never be ordered based on assumptions.
- Proper crankshaft and housing bore measurements are required before selecting bearing sizes and oil clearances.
- If you're unsure which bearing size your engine requires, consult a qualified engine builder before purchasing.
- Because engine bearings are precision internal engine components, incorrectly ordered bearings cannot typically be returned or exchanged.
