Abstract:
A method of repairing a compressor outlet housing includes the steps of obtaining a damaged compressor outlet housing having a radially outer volute, a radially inwardly extending finger extending to an axially extending ledge, a radially inwardly extending web extending radially inwardly from the ledge, and a radially inner bearing support defining a bore. The method identifies a damaged section within at least one of the bearing support, the web, and the ledge, and removes at least the bearing support and the web to leave a remaining part. The method then inserts an insert having at least a replacement bearing support and a replacement web into the remaining part after the removal step. The method then welds the insert to the remaining part to provide a repaired compressor housing. A method of replacing a compressor outlet housing and a replacement compressor outlet housing are also disclosed.
