Drill and use sheetmetal screws to pull it out. Make sure the shaft isn't wobbeling around on failed bearings. Can get sleeve to cover worn groove in flange. Later Bob [Reply]  [No Email]

If I took a picture could you confirm? Mike [Reply]  [No Email]

These shims are for locating the rear of the motor, to minimize the mis-alignment of the drive coupling. Remove the drive blocks and inspect them closely. Any cracks or dry-rot, replace them. They're pretty dear at $80 apiece, but remember, they never break when the weather is dry, warm and sunny. You have to fix it where it breaks, unless you happen to have something bigger you can pull it around with. [Reply]  [No Email]
