Determine shim thickness as required to make each bearing protrude equally (temporarily mark the side requiring the shim with an “ S ”) Measure Hub outside Dimension. Subtract dimension B from A . Subtract 1.123 inch from B Take the difference between 1.123 and Dimension E equals shim thickness to make hub mounting face equal distance from centerline of hub. If D is larger than 1.123 inch temporarily mark bushed side of hub with a U . If 1.123 inch is larger than D temporarily mark unbushed side of hub with a U . If H is greater than E then subtract E from H If E is greater than H then subtract H from E Enter I or J in Shim table. Subtract I or J from C Dimension F = total clearance thickness after centering hub and bearings for preload. Determine shim thickness required to ensure preload: F minus .098 inch divided by 2 = G Orient hub in fork so that S and U are together on the same side.
