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.

Once I had that set up, the nut came off surprisingly with little effort. But now the outside sheave is not ...

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...
