This sale is for one Bearing Set for the left crankcase. This set comes with two Genuine Timken tapered roller bearings, two genuine bearing races, one genuine bearing spacer, and genuine one crank case snap-ring. They will fit Harley-Davidson Big Twin models 1969-1999, and come with the end play pre-set by the manufacturer. This USA made bearing set replaces Harley-Davidson OEM #9028, and should always be replaced when the cases are split. I sell the tool for installing this bearing and the case half in my store. Please check it out.
