A co-rotating scroll comprising:
- a motor having a drive shaft;
- a drive scroll connected to the drive shaft, the drive scroll comprising a first bearing having a first centerline and comprising a first alignment aperture;
- a driven scroll connected to the drive scroll, the driven scroll comprising a second bearing having a second centerline offset from the first centerline and also comprising a second alignment aperture, the first alignment aperture alignable with the second alignment aperture;
- and
- an eccentric idler shaft comprising:
- a first portion operably connected to the first bearing;
- and
- a second portion operably connected to the second bearing, the second portion offset from the first portion;
- wherein each of the first portion and the second portion have a hole provided therein.
