@vacuumdevil - Listen, I get that you're trying to help as well. But you need to take a step down from your high horse, buddy. I am a mechanic. I repair things for a living. And I know plenty about engineering tolerances and subpar parts. Look. I'm going to ask you very nicely: please don't patronize me on the topic of repairing machines.
Further, there's nothing 'bojack' about using an identical part to repair something. What you're suggesting - replacing the entire motor unit because one tiny part is bad - is appallingly wasteful (you're filling landfills), and not cost effective for somebody who's apparently repairing their own vacuum. Your way of thinking, to just change the whole unit, is how repairs are done to things under warranty. And the manufacturer does it that way because they do thousands of such repairs, and the 10% chance a repair (as versus a replacement) will not work, adds up to hundreds of cases that each hurt their reputation and cost them lots of money. The end user fixing ONE or TWO machines is a completely different scenario, and has to be treated as such. With an assumed 10% chance of not working, it doesn't even matter, because it's worth the gamble. Wouldn't you bet money on something with a 90% chance of winning? Those are good odds. And even IF it doesn't work, he'll just fix it again! Waste of money, you say. Less than $10 for a component part, admittedly, it may not work, or he may damage the board trying to solder it, fine. That's a gamble. It's none of our business whether he decides to gamble on that or not. But I'll tell you one thing, that motor unit is probably minimum $100, am I right? How is gambling $10 a 'waste of money' compared to spending $100 outright without even trying to save that money?
I don't know about Chicagomike, but not everyone is made of money.
