Rebuilt the 15g cartridge this afternoon. Quick & easy as I already had a CHRA I had thoroughly cleaned prior to this.
Washed with gasoline remove the oil coating
Housing removed, no wheel marks, which indicates bearing failure was not the cause of the problems with this unit
Mark the shaft, nut and wheel, so it can go back without re-balancing
wheel removed, impeller & shaft tape out of CHRA - obvious oil control ring failure here
removed all the coking from the impeller shaft. Both the oil control ring seat & the forward groove need to be completely clear
New oil control ring installed one shaft, new soaked bearings installed, impeller pressed (by hand) back into the CHRA
Thrust plate & spacer installed, new oring installed
Old parts for reference
Oil slinger, forward housing w/oil control ring & carrier installed w/snap ring
Wheel back on, LHD nut tightened, aligning all three markings
Assembled CHRA in the compressor housing - I forgot to ask on here if the CHRA clocking needs to be altered for install on a redblock
Tools I find extremely helpful in the job
