Measure inner diameter of crankcase bearing race. Substract outer diameter pinion from inner diameter of race. (Inner diameter crankcase race minus outer diameter pinion shaft). The chart will now show you which colorcode to use. 0.5005" to 0.5009" - Green 962887 0.5007" to 0.5011" - White/Gray 555546 0.5009" to 0.5013" - Blue 964387 0.5011" to 0.5015" - Red 964187 Note: All sizes are given in inches (inches x 25.4 = mm). For street engines, that have time to break in, you may want to choose a bearing that falls in the tight side of the range to provide longer engine life. For competition engines that have little or no break-in period choose a bearing that falls into the 'loose' side of the range to prevent seizure.
