5  EP 3 800 004 A1 6  [0028] While the removed compressor outlet housing could be removed and repaired,itisalso within the scope of the method that the replacement compressor outlet housing could have been prepared before the removal of the removed compressor outlet housing, and from a different repaired housing. [0029] A replacement compressor outlet housing un- derthis disclosure could besaidtoinclude a compressor outlet housing, having a volute and a radially inwardly extending finger extending from a radially inner end of said volute.Theradiallyinwardlyextending fingerisweld- ed to an insert. Theinserthasa bearing supportdefining a bore,and the inserthaving a webconnecting a replace- ment ledge to the bearing support, and the radially in- wardly extending finger welded to the ledge. [0030] Although an embodiment of this invention has beendisclosed,a workerofordinary skillin thisartwould recognize that certain modifications would come within the scope ofthisdisclosure.Forthatreason,the following claimsshould bestudied to determine the true scope and content of this disclosure. (a) removing a first compressor outlet housing from a compressor having a compressor impel- ler configured to be driven by a motor through a drive shaft, said first compressor outlet housing having a firstbearing supportportionsupporting a bearing for said drive shaft, said first bearing supportportion connected through a firstradially outwardly extending web to a first ledge, and a first volute connected to said first ledge through a first radially inwardly extending finger; and (b) replacing said removed compressor outlet housing with a second compressor outlet hous- ing,saidsecondcompressoroutlethousing hav- ing a second volute and a second radially in- wardlyextending fingerextending fromsaid sec- ond volute, and said second radially inwardly extending finger being welded to an insert, said insert having a second bearing support placed on said drive shaft to support said bearing for saiddrive shaft,and saidinserthavingasecond web connecting a second ledge to said second bearing support, and said second inwardly ex- tending replacement finger welded to said sec- ond ledge. for a greater amount to a radially outer surface than does a radially outer surface of said axially forward portion an axiallyforwardend ofsaid axiallyrearpor- tion, and said second finger abutting the axially for- ward end to provide axial alignment. 3. The methodas setforth in claim 2,whereina portion ofsaid axially rearportion which extendsradiallyout- wardly to a greater extent than does said axially for- ward portion ofsaid secondledge issacrificed during said welding; and/or wherein a first distance is defined between said ax- ially forward end of said axially rear portion to an axially forward end of said axially forward portion, and a seconddistance is defined between an axially rear end of said axially rear portion to said axially forward end of said axially rear portion, and a ratio of said first distance to said second distance between .731 and .821. 4. The method as setforth in claim2,wherein said sec- ond volute andsaid second radiallyinwardlyextend- ing finger are said first volute and said first radially inwardly extending finger. 1. A method of replacing a compressor outlet housing comprising the steps of: 2. Themethod assetforth in claim1,wherein saidsec- ond ledge has a extending portion providing a radial supportlocation forsaidradiallyinnersurface ofsaid replacement finger, and said second ledge having an axially rear portion extending radially outwardly Claims 4
