steel case side of the lip seal must be engaged with knurled tangs of installer so that flared-out side of lip seal is facing and installed towards the
compressor. In stall shaft seal protector J 34614 on the lip seal. Place the seal protector J 34614 over end of compressor shaft, and slide the new
