Could You Help Me?

[bagintheback]

I have a Eureka The Boss 7671 that has a problem. The motor is slowing down, and it's burning. If I have to replace the motor, it's okay, but can someone tell me how to get the motor off the bag assembly. If I can fix it easily, could you please give me a detailed way to take apart the motor. I have a trox screwdriver.

Thanks,
Nathaniel

Try this....

Hi, Nathaniel. Try this place at 43rd ave. & Bell rd. called Super Vacuum & Janitor Supply. This place is owned by 3 brothers that I've known for more than 20 yrs. They are very honest and can fix any brand of vacuum there is. I hope this helps....Bill....

Can I fix myself? If I can't, I'll go to those guys, even though it's far away.

If you have knowledge.

You can fix anything you put your mind to. However when you give us vague descriptions of problems it is a little difficult to tell you exactly what it is. Can you post a video so we can hear it? Can you tell us what kind of smell it is (rubber, acrid, electrical, sweet?) Can you post pictures of the unit, so that people that don't know the model numbers, but know the machines can give you advice? With your short post, it is like asking us to put an envelope to our forehead and tell you what is inside.

Thanks!

Here are some photos of it.

Oh, i forgot. The burning is more like the motor and the motor spins down about half way and then comes back to life.

OK!

That was the machine I thought it was.

To remove the handle from the motor, you will see right under the lower bag housing a screw. It is a phillips screw. Remove that screw, and then insert a straight headed screwdriver between the motor and the handle and twist. It should move a little bit. Then have a friend hold the motor and you pull on the handle and they will seperate. It would be much easier if the motor was still attached to the base because then you could pull straight up on the handle.

See the picture. It looks like you've taken that screw out. I recommend that you put the motor back on the base and pull straight up on the handle.

Those motors are garbage im my opinion. I recommend waiting for a garbage machine with a good motor and replace it. I bet you have bad carbon brushes and it is arching.

I tried to do that, but it wants to stay on! Could the cord be a problem?

 

[extraditgitzz]

No.

Cord is not the problem.. Most likely dirt is the problem. That needs to make a tight seal so that it does not leak. Put the motor back on the base, secure it and then put your foot on the base and pull straight up wiggling back and forth. The seal and dirt are keeping it together, keep working at it.

Yup, the cord is not the problem as these type vacs use a fixed plug & socket arrangement where the neck joins the motor casing (for easy motor swapping I imagine).

As Dennis says, it is the dried caked smutz between the ridges of the internal rubber gasket seal around the motor fan outlet channel inside the handle portion that makes it seem stuck. No glues are involved, just friction fit. Wiggle, wiggle wiggle and out she comes. I too would remount the motor in the base for this so you can do it standing up.

Or you could lie on the floor with your feet pressing both sides of the motor and lever/wiggle the motor casing off with your arms firmly gripping the handle/bag chamber. It will let loose quickly so best to have your feet and the motor against a pillow & wall and keep your chin/face out of the way of the handle.

I'll try that. what can I do to the motor? If I can't do anything, does Eureka still make these motors?

 

[extraditgitzz]

Well.....

Get that puppy apart and then give us a heads up and we will figure out what to do.

 

[bagintheback]

Okay I got the motor out, but I'm having trouble with removing fan. I removed the bolt. Here are some picture of it. I'll keep the photos big so you can see it in detail.

Got the case off. Here are the photos. Could a ton of dust on the motor make a difference?

Motor looks good for the most part so far

I can see that the carbons are fine. I would clean the motor up real good. I would not remove that fan unless really necessary, as it could lead to you having difficulty putting the armiture back into the motor. Once you take off the nut for the fan, wrap a cloth over the air fan for the motor, then hold that fan (if you don't put a cloth over it you will cut you hand) and twist the dirt fan while pulling and it will come off. Be careful of the cooling fan because you can yank it right off the amiture and ruin the armiture. Give us a pucture of the fan when you pull it off.

I found the burnt spot. I"l call Eureka and see if they will sell me a new motor.
