To repair worn-out bearing lugs, the worn bores are enlarged and are then built up by the application of helical layers of weld material. The bores are then enlarged by metal removal to the desired diameter. This is a significant improvement over the prior art method wherein worn lugs were repaired by inserting a replacement sleeve and welding it in place. Such sleeves to be weldable had to be made of relatively soft material and therefore were subject to rapid wear. In contrast the welded fillets applied in the present invention produce a hard material with good wear resistance. |
