 c. Take turns on each bolt tightening them down clockwise. This will cause the bearing to push back into its place in the channel somewhat evenly. Every so often hit the top of the plate with a hammer to bring the shaft through the middle of the bearing as well as keep moving the bearing into the outer shell casing. Keep turning, hammering until the shaft is snug with the inside lip of the channel.

 '''2. Reinstallation of the Shaft: '''
-a. Place shaft (small end first) into the shaft channel from the left side. Make sure the shaft goes all the way through and completes its way through all the connecting rid bearings. Also make sure that the shaft is level, and is not at a diagonal in the channel it is being put through.  Using a bearing press, take the plate of the press and align it with the screw holes on the right side of the compressor.

-        There were many Alan bolts that we had to remove during the dissection. Unfortunately, a select few of these Alan bolts and Phillips heads stripped. The nature of the shape of the hexagonal Alan key makes it susceptible to stripping. The hexagon is close in shape to a circle, and it does not take much stripping before the Alan key is no longer able to “catch” inside the hex bolt. The stripping is caused by the high moment resistance the bolts give to being loosened, as they are tightly screwed into place.
