A seal plate for an air cycle machine includes a substantially disk-shaped body having a first side configured to be coupled to a compressor housing of the air cycle machine and a second side configured to be coupled to a turbine housing of the air cycle machine. The seal plate also includes a timing pin slot configured to align the first side of the seal plate with the compressor housing. The seal plate further includes a plurality of fastener holes distributed radially in an asymmetric pattern. The plurality of fastener holes includes an alignment fastener hole configured to align the second side of the seal plate with the turbine housing. An angular offset between the alignment fastener hole and the timing pin slot is about 38.45 degrees.
