[0016] An intermediate part 153 is shown in Figure 4B having the finger 58 defining a radially inner surface 222 afterthe cutat102 (seeFigure4A).Radiallyinnersurface provides a radialdatumpointat222 forsubsequentrepair steps. As shown schematically in Figure 4B, the radially inner surface 222 and an axially rear surface 221 of the remaining finger 58 are machined as at 106 to reach a desired datum. As can be appreciated, the location of the several structures in the compressor outlet housing must be precisely aligned for the overall compressor 20 to operate. [0017] The cut 202 can be made at the pointthe finger 58 joins the ledge 39 or can remove a small portion of the finger.Witheitheroption,the remaining fingerportion is still called a finger for purposes of this application. [0018] An insert 200 is illustrated in Figure 5. Insert 200 has a replacement bearing support 202, whi roughly matches the bearing support32 insize,material, etc. A replacement web 204 (also matching the web 38) extends from the bearing support 202 to a replacement ledge 206. Replacement ledge 206 has an axially rear enlarged portion 208 and a forward extending portion 210. A first radius R$_{1}$ is defined from a central axis X of a bore 209 in the bearing support202to an outersurface 211 ofthe forwardextending portion 210.A second radius R$_{2}$ is defined from axis X to the outer surface 212 of the rear portion 208. An axial distance d$_{1}$ is defined from a rearpoint220 ofthe forward portion 210 to aforward end 231 of the forward portion. A second distance d$_{2}$ is de- fined between the forward end 220 of the rear portion 208 and a rear surface 207. [0019] As can be appreciated, surface 220 is both the forward end of rear portion 208, and the rear end of for- ward portion 210. [0020] In one embodiment,R$_{1}$ was 4.78 in. (12.14 cm) and R$_{2}$ was 4.90 in. (12.45 cm). In embodiments, a ratio of R$_{1}$ to R$_{2}$ is between .963 and .988. [0021] In one embodiment, d$_{1}$ was .930 in (2.36 cm) and d$_{2}$ was 1.20 in. (3.05 cm). In embodiments, a ratio of d$_{1}$ to d$_{2}$ is between .731 and .821. [0022] As shownin Figure 6A,insert200 isnow insert- ed within the remaining finger 158 of the intermediate part 153. A weld joint 310 is formed to connect the two. Electronbeamwelding ispreferably utilized.The forward end 220 of the rear portion 208 ofinsert 200 abuts a rear surface 221 of the finger 158. An outer surface 224 of the forward portion 210 supports the inner surface 222 of finger 158. As can be appreciated, the location of the axially forward surface 220 of the rear portion 208 and the outersurface 224 ofthe forward portion 210are care- fully formed to a desired size and mate with finger 158 to properly position the remaining 153 in both radial and axial directions. [0023] As shownin Figure 6B,the forward surface220 of the rear portion 208 and a forward surface 221 of the finger 158 provide axial location. The inner surface 222 ofthefinger158 andthe outersurface 224 ofthe forward portion 210 radially position the two portions together. The weld joint310 is shown.By having the enlargedpor- tion 208, backup material is provided which will prevent gas entrapment at a backside of the weld. At least some percentage ofthe rearportion 208 issacrificed to provide the weld joint 310. As such, the repaired part will likely not have a surface extending to the original R$_{2}$. [0024] As shownin Figure 7A,a flowchart ofthe meth- od according to this disclosure could be said to include a step 500 of removing the damaged housing from the compressor. Next, a damaged section is removed from the damaged housing at step 502. Next, the remaining portion of the damaged housing is machined to a datum at step 504. In step 506, an insert is placed within the remaining portion.Atstep508,the insertiswelded tothe remaining portion. At step 510, the repaired compressor housing is replaced in a compressor. [0025] Figure 7B shows a repaired compressor 520 now having a compressor outlet housing 230, which in- cludes the insert 200 and the remaining part 153. [0026] A method ofrepairing a compressoroutlethous- ing under this disclosure could be said to include the steps of: (a) obtaining a damaged compressor outlet housing having aradiallyouter volute, aradially inwardly extending fingerextending to an axially extending ledge, a radially inwardly extending web extending radially in- wardly from the ledge, a radially inner bearing support defining a bore; (b) identifying a damaged section within at least one of the bearing support, the web, and the ledge; and (c) removing at least the bearing support and the web leaving a remaining part; (d) inserting an insert having at least a replacement bearing support and a re- placementweb into the remaining partafterstep (c);and (e) welding the insert to the remaining part to provide a repaired compressor housing. [0027] A method of replacing a compressor outlet housing under this disclosure could be said to include the steps of (a) removing a first compressor outlet hous- ingfroma compressorhaving a compressorimpellerdriv- en by a motor through a drive shaft, the first compressor outlethousing having afirst bearing support portion sup- porting a bearing forthe drive shaft,the first bearingsup- port portion connected through a first radially outwardly extending web to a firstledge,and a firstvolute connected to the firstledge through afirstradiallyinwardlyextending finger; and (b) replacing the second compressor outlet housing with a second compressor outlet housing, the second compressor outlet housing having a second vo- lute and a second radially inwardly extending finger ex- tending from a radially inner end of the second volute, and the second radially inwardly extending finger being welded to an insert, the insert having a second bearing support placed on the drive shaft to support the bearing for said drive shaft, and the insert having a second web connecting a second ledge to the bearing support, and the radially inwardly extending finger welded to the sec- ond ledge. 3
