ABSTRACT:
An apparatus for use in providing a load on a bearing mounted to a shaft includes a setting gage configured to be received on a shaft and configured to engage a nut on the shaft. The gage includes an inner portion and an outer portion rotatable relative to each other. The inner portion includes an outer perimeter contacting an inner perimeter of the outer portion. The inner portion has an inner opening having an inner circumference mirroring a shape of the shaft and shaped to inhibit movement between the inner portion and the shaft when the shaft is received in the inner opening. The outer portion has an outer circumference comprising at least one radially projecting member configured to engage the nut to inhibit movement between the outer portion and the nut when the gage engages the nut. The inner portion includes a start position indicator on the outer perimeter and a stop position indicator on the outer perimeter. The start position indicator includes a start position for a marker of the outer portion. The stop position includes a stop position for the marker when the outer portion is rotated from the start position toward the stop position such that the marker is aligned with the stop position to achieve a desired amount of endplay of a bearing mounted to the shaft.
