The holidays are over and I got power to the shop working again. I came through the other side of Christmas with the bearing puller I needed ,a new shop vac, air compressor, Porter Cable cordless set, and a few miscellaneous odds and ends for the shop. So I'm back in the shop after being dark for almost a month.
Bearings
I replaced the bearings on the drive shaft and motor yesterday. The 6202RS bearing I purchased for the quill had an ID that was too tight. I ruined it trying to press it on the shaft. It now hangs at the same point every revolution. That's still better than the old Fafnir 202KDD5 that feels like it has gravel inside. I've decided to break down and spend the money on a good Fafnir replacement. The few websites I've found that sell it require a business account so I guess I'll have to pay the $30 to get it locally.
This is the original quill bearing and the cheap, sealed replacement.
These are the motor bearings. Originals were 77203, "Hoover" manufacturer. Replacements are sealed 6203RS
The drive shaft bearings are 6205RS, replacing the original 6205ZZ KOYO JAPAN bearings. So much for buying American.
A.O. Smith Motor
Hopefully I'll pick up a quill bearing on Monday, but in the mean time I'm working on putting the motor back together and I need some help. It's a1 and 1/8 hp A.O. Smith motor. At the capacitor end of the motor, the bearing fits inside the end shield and a keeper ring screws to the back of the end shield to hold the shaft in place. Strangely, one of the screws that holds the ring in place is longer than the other. When I put this back together, the long screw digs into the end of the rotor (picture below). I took a lot of pictures when I disassembled this thing and none of them shows extra washers or other parts under the head of this longer screw. Anybody out there know what I'm talking about? Can anyone help?
