Difficulty getting to quill bearing

Hi all, I'm close to finally collecting all five bearings to be replaced (The control sheave bearing seems just fine to me. Go figure) and I've done my best Everett impression to get them measured precisely. Here are the two motor bearings and the two Gilmer Drive bearings: IMG_4046.small.jpg But th...

Re: AO Smith 3/4 HP Motor Rebuild

Hi all, @chapmanruss, your history lesson helps quite a bit. Thanks for taking the time to write that out. And @everettdavis, you were absolutely correct. I checked the vent cover and sure enough, it says "Mark 5" right above the serial number. JPG, I did as you suggested and pushed the fa...

Re: AO Smith 3/4 HP Motor Rebuild

Thanks, Everett. There are some really good details in that post. I'm surprised about your comment regarding variations in the bearings. I would have thought that a given company would have to ensure that a part number was consistent across lots. I focused on NTN because that's what I see being sold...

Re: Removing nut from AO Smith 3/4 HP Motor Shaft

Hi guys, Thanks for the responses. I saw the tool in Jacob's videos, but it seems to assume a washer that is significantly larger than the clip holding it in place. On my motor, the spring is just barely larger than the nut, so it doesn't look to me like the dimensions specified will work. Is there ...

AO Smith 3/4 HP Motor Rebuild

Hi all, I'm sure this has been asked before, so I apologize in advance for not being able to find the reference. I've read through threads on the AO Smith motor, Mickyd's rebuild thread, ShopSmith's exploded diagrams and the docs on Everett's Google Docs archive, but I've been unable to find a refer...
