I was finally able to get the motor apart. I thought some of the screws were stripped, but apparently I found a size of screw bit that actually got them out. The motor was just caked in dirt a filth. Judging by the amount of carbon dust marking on the armature, this machine really hasn’t been used all that much. After cleaning it, I thought it would be best for me to install new bearings. The old ones were sounding like metal on metal. The fan side was easy to do, but apparently I am having trouble installing a bearing on the belt side. Like has anyone ever had this happen to them? I hope someone knows what to do since I won’t be able to use this machine without all of the bearings obviously.

Question is 2 vague. The bearing installed and I'm guessing one on the field coil.

My question is that I can’t install the bearing that goes on the belt side of the armature. Like it literally won’t even go down when I try to install it. I might contact Ametek, the company that made this motor to see how I can install the second bearing.

Ametek isn't going to be of much help. Does the belt side bearing slide up and down at all or no? Bearings are usually press fitted onto the armature without the intent of replacement in mind.

When I go to install it, the bearing sits crooked and doesn’t fully go on the armature.

Defective Bering?

Maybe you have a defective bearing assuming you changed it and didn’t just re-pack the original. If the old one came off and you have the correct size the new one should press back on. If you have a new bearing that is the only variable that changed so the bearing would seem to have to be at fault.

I have multiple new 608 bearings, which are the correct size. I went as far as trying to put the original bearing back on and it even didn’t go on. I know that using a socket and tapping it with a hammer is the correct way of installing bearings. There must be a different way you install the bearing on this armature. That’s the only way they would’ve done it from the factory. I can’t really find another way of doing it, so I probably will just contact Ametek and see what they will say.

A bearing puller/presser would be needed in this situation. These are assembled with pressurized machinery, so you need to have a lot of strength exerted on the parts to get them on. A human simply is not capable of the force needed to push it on evenly. You can get good results by crafting a vice and holder out of wood blocks and then using a drill press to crank it down.

Huskyvacs, good idea! Or, assuming it can also be used to install bearings, why not just use a Kirby Bearing Puller? Kent Oyler used to carry them in his Ebay store, perhaps his wife still has some laying around.

I forgot to write it in my post, the specific name for the special tool used to press or pull apart ball-bearings is called an "Arbor Press". The one in this photo found in google can put down 3 tons of force on any poor hapless part that comes under its ratchet.
