That's what I'm calling the Robot Coupe R2U (a commercial-grade food processor) that I attempted to repair tonight. Not only is it a pain in the posterior to put back together, but the reason it broke is because someone dropped it on the floor. It costs about $1200, thus the upper management are not inclined to purchase a replacement, so I am trying to fix it myself.
After purchasing a new casing to replace the broken one, and putting it back together, I found that it works, except that you have to manually get the spindle moving, because it can't get started from a dead stop. Also, a brushing noise can be heard when it slows down, indicating some sort of friction in the motor. I theorized that there is a lack of lubrication within, mostly likely within the ball bearing.
When I took it apart, my theory was confirmed. The brushing noise was coming from the top bearing, and around it there was a mess of burnt lubricant. The sealed bearing must have gotten cracked when the machine was dropped, causing it to leak out lubricant. So far so good.
The trouble began when I tried to take apart the housing of the motor. I couldn't get the damn thing apart. I couldn't find the information I needed online. I got a repair manual for the food processor, and it tells you the part number of the bearing, indicating that it can be replaced, but it gives no directions on how to do that. The motor manufacturer's site was no help. I am at a loss. Does anybody know how I can replace the top bearing on this thing?
I removed the screws that tightly held together the top and bottom aluminum pieces, but I have been unable to remove the top one. (There's no way the bearing can be removed until it is disconnected, because the bearing is seated within its underside.) The top piece will rotate, so I know it isn't glued into place, but it won't pop off even when I tap it with a hammer.
Any ideas? The only thing I can think to do is to try heating it up or using a prybar in some way, but I want to avoid damaging the 1 HP motor.
Also, see that laptop in the background? Tonight I removed over 9000 viral files from it. No, I'm not exaggerating. 9636, to be exact.
(Shit, it's after 6 AM already... Welp, see ya when I see ya.)

What is the cost for a replacement motor?

I was in the same situation with an oil burner about fifteen years ago. I had to seek professional help.

I like your dresser. What kind of lizard is that?

No ideas except, as Juan said, to get professional help. I've never been particularly mechanically inclined. :/
But why won't the top screw come out. Is it just too tight, or is it sealed in some way?
Also, this looks like something my brother would try to make a bong out of.

A little over $500. The bearing is about $40.Sat May 28, 2011 9:49:44 am

... Wellll, I'm not at the end of my rope yet, but if I get this bearing replaced and put the monstrosity back together again and it still doesn't work right, then they might be coming to take me away, ha-ha ho-ho he-he.
Seriously, I considered taking it to someone who specialized in electro-motor repair, but I like to fix things myself if at all possible. I found out tonight that a coworker has a bearing puller he's willing to lend me, a tool that in the motor's current state (see below) will probably do the trick, so that's the plan of attack now.

It's a nice dresser, all things considered. My Aunt and Uncle had it since I was a tyke, later used it in their outside recreation room at a campsite, and then handed it down to me. Like the matching bureau, it is US colonial style (though certainly not colonial-age), which I've always found aesthetically pleasing, although it doesn't match the style of most newer/southern homes. And it tends to be rather heavy.
And that is the only kind of gecko with eyelids, a Leopard Gecko. His name is Asa. He loves hunting crickets and being left alone most of the time. He had a life partner, but sadly she died of complications related to a head abscess about 2 years ago. (Very soon he will meet a young replacement.) In this picture he is doing the equivalent of puffing his chest out and looking as tough as possible:

There is no screw left to remove. I think the problem is that there is so much friction between the shaft, the bearing, and the aluminum housing of the motor that it will take a lot of specifically-controlled force to break it loose. It isn't really bound in any way other than that. Tonight my boss and I were successful together in breaking it down even further with one of us holding it and the other banging at it with a hammer, but still we couldn't get that one damn piece off, the big circular one wherein the bearing is mounted at the center of a cross:

Haha. That reminds me of the bit in No Cure For Cancer where Leary talks about the stoner inclination to make a bong out of anything and everything. If your brother made a bong with airflow powered by this motor, he could probably forcibly take the biggest hit of his life in approximately 0.35 seconds. I, personally, was satisfied with using a modification of one of those mini vacuum cleaners that ran on 4x AA batteries. When I was into it...

Well, I hope the bearing puller works, then! Seems like a lot of work is going into this; I hope it works VERY well once completed.

I love Dennis Leary; some say he's a hack, but I don't see it. Maybe it just takes a different sort of humor. But that's one more example of how I was never mechanically inclined; most I ever did was turn a soda can into a bong. My brother has a knack for that kinda thing, though, at least when it comes to getting high. His most torturous tool is a gas mask with a hose attached, which then attaches to a bong. Not as quick as this thing would be, but I've seen it make him vomit for half an hour afterward.
I'm so happy I got out of that phase at a relatively young age. . . . Still fun to think about, but I don't miss it.

A lot of work has gone into this, but I will be paid for my part no matter what. My work on repairing the thing is being treated as another outsourcing job, which benefits my boss and myself. He is cutting down the kitchen staff labor hours, and my services are less expensive than most specialists, which is only fair considering I learn my way through jobs like this. Bottom line I will make as much per hour working on this food processor as I would working on the internals of a computer, via my personal electronics sales & service business.

I also love Denis Leary, and due in no small part to the fact that he reminds me a lot of my family and upbringing.
I had a friend who rigged a gas mask as a smoking device once, but I wasn't enamored of it, even then. I was from the old school (fool), where if we wanted a gas mask we'd hold a cap over our faces, with the bill down, and someone would blow the smoke into it by way of the semicircle adjacent the strap. (Obviously this didn't apply to fitted caps.) Or maybe we'd “shotgun”, where the recipient held a blunt in the mouth, as another would wrap lips around the other end, taking care not to touch the cherry, and blow the smoke into the recipient. Also we would fashion 3-liter polystyrene bottles into gravity bongs. Vomiting was a shame, and very rare is the time when I remember that being the result.
I didn't get out of smoking regularly until 2006, and I didn't get into smoking very rarely until 2009. Like you said, it's still fun to think about, but I don't miss it. (Smoking more than very rarely, that is.)
