Bought a Rexair model B on ebay on Tuesday and got it today. Started taking it apart the clean it and replace the bearings. I'm still trying to get the bearing plate off the bottom, currently soaking it with PB blaster. Thought I would take a couple pictures since someone was asking what the motor in an A, B or C Rexair looks like. The motor has the upper bearing out of it as well as the brushes. I put the bolt back into the armature that holds the upper bearing in place. The first picture is of the motor and the second is of the armature and fan assembly. Once I get the bearing plate off then I can get the fans apart.
this is after I have put the rubber gasket in between the bearing plate and motor housing then screwed all that back together then set it on the base and before I put the outer shell on. The outer shell is what holds the gasket over the lip on the base and holds the motor in place.
