TABLE OF CONTENTS The forms of damage that can occur in the steeple region of wheels and rotors are such that certain refurbishment, or corrective actions can be undertaken. Some of these actions should be considered temporary, sufficient to allow the rotor to be returned to service for a period until a replacement component can be produced. Other options represent a permanent repair, and while they may require time for situation evaluation and redesign, the costs and delivery times involved are significantly less than those required for the purchase of a replacement rotor. The following methods represent a selection of the actions that can be undertaken, but are not considered exhaustive. They do, however, represent the major corrective actions that are available.
In this section, the requirements for the weld rebuild of wheel rims should be considered. This method of correcting a damage situation should be considered the final option, when other simpler corrections cannot be achieved. However, this process has now become mature enough that there are situations where this is preferable to other methods, based on both lower costs and turnaround time. This possibility can only be determined from a complete evaluation of the options available in each situation.
In the case of relatively light damage by fretting, gouging, corrosion, or other action on the load-bearing surfaces of the roots, it is possible to skim cut these surfaces to re-establish a suitable load transfer area.
