Abstract
A method for determining a thickness of a shim for setting up a predetermined preload of a bearing assembly that rotatably supports a shaft within a housing. The bearing assembly includes front and rear tapered roller bearings. The shim is disposed between a bearing supporting shoulder of the shaft and an inner cone of the rear bearing. The method comprises the steps of: measuring a distance X from an end face of the shaft to the bearing supporting shoulder thereof; measuring a height B of the inner cone; mounting the shaft within the housing; applying a load to the inner cone of the rear bearing corresponding to a predetermined preload; measuring a distance XL from the end face of the shaft to the inner cone of the rear bearing; and determining the thickness W of the shim in accordance with the following equation: W=X−XL−B.
