Many sites show the old motor but ship the new one. The only photographic evidence that I have of the old motor being sold new is on EBay. These tend to have a bearing with red seals on top and, I have a hunch, are made by Perfect, not Sanitaire.
I’ve given it thought, and I have concluded that the new motor is at least as good as the old one. Quite possibly, it is better. The new style motor is a) designed to have a longer lifespan (2000+ hours), and b) is more easily serviced. The old motor is assembled using basically some big, proprietary press and is difficult to take apart. New motor is held together with 4 fasteners on top and easily comes apart for bearing relubrication or replacement, if ever needed. But, we are all entitled to our opinions. If you dig the old design of motor, I hope you find one! 😃 CLICK HERE TO GO TO broomvac's LINK on eBay | ||

I jusr love the sound of the old one, though it is good to know that the new motors have a longer life. | ||

@superocd I would be willing to bet that's just an old stock photo and you would receive a newer motor just based on the price.
@broomvac I know they're claiming a 2000 hour lifespan I can tell you in the field that is not the case. Those new motors have about half the lifespan of the old ones. I'm not sure why you think you need a press to service the old motor? There are two screws that come out after you take the carbon brushes out and you can change the bottom bearing plate or top bearing plate as a whole. The older style motor at one time had all the parts available to service the motor. The newer motor no longer has that part availability. I talked about this in this video a little bit. | ||

From my experience the new motors are nowhere near as good. My oldest Sanitaire is a 1983 SC686 with the original metal motor and still runs great. Was used commercially originally I'm guessing because it had a magnet bar on it when i got it. My 1987 SC886B also has the original motor and runs perfect. I bought a 2007 SC886E2 with the new plastic motor in 2013 only 6 years old not abused and the motor was shot. My newest Sanitaire is the 2019 Bissell Sanitaire SC886F i bought on ebay 2 weeks ago with a bad motor. It obviously sucked something hard up and busted a few blades off the fan. Also busting the bottom on the motor up. I've seen older metal topped motors with fans that completely exploded and didn't harm the motor let alone destroy the whole bottom of it. I replaced it with a metal motor. Now my 2019 SC886F has a new old stock metal topped motor i was saving. Here's a pic of the bottom of the plastic motor

Thanks for sharing your thoughts.
Funny enough, my experience has been the opposite. The original old style motor which came in my S661 was a goner. The bearings were worn, the shaft was warped, and (I guess I can’t blame the motor for this, but...) the bottom plate was broken from when the previous owner exploded the fan. My new style motor has been flawless. I’ve put a decent number of hours on it and have had no problems. That said, I take care of my vac. That can’t be said for many of the commercial users. 🙂 As far as disassembly goes, please see the linked thread. I didn’t write it up, but I did read it, and it sure seems like there is no good way to disassemble the top end of the old motor. Take a look at that cooling fan. It wraps around the upper bearing such that nobody could fit a traditional bearing puller in there. If you can’t get the upper bearing off, the armature cannot be removed from the upper housing. No way. I’d really like to know how to take this apart without a press. How could I have replaced the upper bearing in my S661’s old motor without Eureka’s proprietary tools? It seems there is no way to remove the upper bearing from the armature. In contrast, the new motor can be disassembled with the removal of 4 screws. No fuss. Once it is apart, access to the upper bearing is unobstructed and it can be pulled off with a traditional puller. Seems like a better design to me, but that’s just my opinion. I don’t see how a little steel disk adds much value to an outdated motor which is 95% plastic elsewhere. But again, that’s just my opinion. 😬 CLICK HERE TO GO TO broomvac's LINK | ||

@broomvac I can tell you from all that years in the industry I've rarely seen them come apart like that. Usually the bearing comes off with a stamp sheet metal top.
If not I've always been able to watch them off with just two screewdrivers. Keep in mind I form these opinions after working on thousands of machines. | ||

Hmm
Idk I found this motor in the link. It's a 8.5 amp but would fit in my s667a so I imagine it would fit yours.
