Hey guys, I recently purchased a Eureka Boss from a local thrift store for 10.00 but it only worked for a minute then shut off and never turned back on. I wanted to replace the motor, is it easy to replace? Do they still make this motor? It's a 5.0 amp. Thanks. Here is what it looks like

These motors are very simple to replace, but have you checked the motor carbons? If so, and all else fails, you might be able to find a good used motor, or you could buy the new 5.0 amp blender style motor thats in the newer 1934's than yours, but it will still fit into yours. If you replace it with the new motor though, you will notice that the motor is more high pitched, and doesn't sound quite like the motor that was in yours previously. I would recommend trying places like ebay etc. to try and find a new motor. They're great machines though! If you want to take the hood off, flip the machine upside down, and you will see two black screws, one on each side (left and right). Once you remove those, you can flip it back to its normal position facing up, and lift the hood off. There are 4 screws holding the motor in that you will see around it, which I believe are T25 screws. Once you have those out, the motor should just lift right out. You can simply cut, strip, and marrett the wires to the new motor, and then just screw it down, and put the hood back on and you should be good to go. I have the newer 1934A and it works great! I love how lightweight it is, although I wish it had the older motor in it, just because I like the sound of the older ones better :P

Hope this helps!
Daniel :-)

This vacuum is from the 1990s, but Eureka used that same deign for most of their uprights ever since the 50's. Here's the current version of that model.

I will post a picture tomorrow of where to locate the carbon brushes. Its easier for me to explain with a picture where I can circle exactly where they are so you know where I'm getting at. I have an old Eureka upright, and the new 1934, so I will post a picture of both the new and old motor so you know which you have, and where to find the carbon brushes on them to check if they're worn out. It could also be a loose connection or short in the cord, so make sure you check all the connections when you take the hood off, or try and run the motor with a different cord if you happen to have one. Also, Im not sure on a date, but I know its an older one because of the white Dial-A-Nap dial. Mine is new, and the dial is black. I will post pictures tomorrow for further information.

Daniel :-)

Here comes the pictures, I hope this helps! :-) The first one shows you a step I missed in taking the hood off. Using a T25 screwdriver or bit, unscrew the screw that is inside the dial. This releases the height adjustment, and it allows the hood to come off. when you put the hood back on and want to put the dial back on, lift the base up and pull down on the front wheels underneath, and then put the dial back while holding the wheels down. This will allow you to put it back in.

Daniel :-)

Newer Blender style motor. The old motor is called a "pancake style" motor based on its appearance.

Perhaps its the switch?

I had a sanitaire that did the same thing and it turned out to be a broken switch.

Maybe I should start with the switch, prior before it quit working I smelled a slight burning smell then it would not turn on again :(

The motor might be burnt right out. If its not the switch I would just replace the whole motor.

Just my opinion.
Keep us posted :-)

You can take an ohm meter (or a multi-meter) and check for continuity on the motor.  If you get a reading off the motor wires, then you know it's the switch.  If you haven't used one before, I can help you out and they're pretty cheap to buy too.
