ABSTRACT:
This invention is directed to the repair of cast composite vehicle wheel hubs used specifically on trucks. Such hubs typically have a plurality of spokes extending from a boss with webs extending between the spokes. The hubs are cast of composite metal alloy material which cannot be repaired by conventional welding methods due to the metallurgical make-up of the hubs. Damaged outer spoke portions are repaired by fitting an annular band of material by removing a portion of each of the outer spoke surfaces. The band is secured to the spokes by using an intermediate bracket of weldable material secured by mechanical fasteners to the spokes of the hub.
