Swapping from a 143T to a 143TC motor

That’s correct, the fan end gets the wave spring. Since the drive end bearing is captured, the expansion is compensated by the wave spring in the fan end.

I did find it interesting that the bearings were mismatched in regards to manufacturer of the bearings. Someone else changed the FAG bearing in. In all my experience with baldor motors , i have not seen the brand in their products as an oem bearing.

I wouldn’t doubt it. Who ever did that was probably the same person that did not seat the bearing all the way down. I ordered both ABEC 1 C3 clearance SKF bearings to replace them. I will be in California visiting my daughter when they arrive but I currently have the saddle and cross slide torn down for cleaning and inspection right now so it’s not like I can use it anyway. It should be jamb up when I get it back together though

The only thing that sucks is I have a drawbar project to do for my mill. Requires quite a bit of lathe work. Guess that will have to wait as well

Just letting you know ow what I found. It was the rear bearing that was bad

Yes sir, Not gonna lie, I was starting to get a little frustrated with it. Ended up being the smaller of the two bearings. The FAG was the bac one

Half of being successful is the ability to keep going, when others would quit.
Congratulations on your success.
