To use our bearing chart

• Determine your engine case main bearing diameter. If you have your old bearings you can measure these. If the case is needing a line bore check with your machine shop to see how much will be cut.
• Measure the crankshaft bearing journal size to determine the correct ID Again if the crankshaft requires machining you will want to check with the machine shop to determine what the final size will be.
• Select the correct OD from the top row. Select the correct ID from the left column. The correct bearing set will be where the two rows intersect.
