Unfortunately, I broke the case getting the motor out to lubricate it. I pried off the two clips at the center using a screw driver. On flew off into a patch of English ivy and I've been unable to fine it. And one of the plastic lips where the clips lock top and bottom together broke. I don't have the proper tool to open the center clips. The motor bearings are pretty well rusted anyway. My best bet is a whole blower unit including case and regulator. I'm still looking.
