I picked this guy up from a vacuum shop today for $40. The owner had it stored in an old Ford pickup next the store, so the vacuum has been rained on a few times. Even knowing that, I thought that even a part-bad Dimension 1000, which from my understanding is quite rare, would be worth the money he was asking.

It turns out there is something wrong with the motor. It sounds stalled. The best description I can think of is like a water pump running without water. Otherwise the bag door lid does not want to be put back on. It took some effort to take it off, but now it refuses to shut. So I'd some help in attempting to get this motor running.

If the motor is hopeless, I will be completely willing to part it out for you guys. I'll sell everything but the power nozzle, unless someone gives me a good offer.

Thank you in advance for the help.

It sounds to me like the bearings are seized up, probably from getting wet.

That is what I thought: bad bearings. Does anyone know how to service those?

Not a clue. Do you have a good vac shop locally?

Not really. The only shop I know of is the one I bought it from! Maybe John Gregory (GUARDSMAN69) could assist me? I can talk over email or phone. Whatever is easiest.

That might be a good idea, I have a filter queen that needs new bearings, but I don't have the tools needed to remove them. You might open up the case of the vacuum, take the motor out, and see if it turns freely (obviously make sure its unplugged) and check out the brushes and armature to see if it is making good contact.

It must be national Hoover Dimension 1000 day, how come I didn't find one? Another member posted one found under the vintage threads.

Oh what wonderful canisters. The purring Hoover Quadraflex Powermatic nozzle.

Congratulations, terrific find, you'll love it, looks to be in great shape. If you can, I'd love to see a shot of the agitator.

Enjoy and Happy Hoovering!!

Ok, I wow, I missed the boat on this one. I saw the picture and got excited right away.

The bag door on these is a little stiff to remove. Pull up on the top front handle while using other hand to push down on the suction unit below handle if that makes sense. Once you've done it a few times, its a cake walk. Also the bag door on these is not supposed to close if there is no bag in place? If door is shut with bag, that absolutely explains your problem!!! Is there a Type M Hoover bag installed, and is it installed properly. The collar is only supposed to go one direction. Some of the bags have a cut out notch in top and some don't. Tilt in bottom of card board collar first, then push in top and release spring holder on top of card board collar.

To service the motor, you need to remove the two rear wheels. On the bottom of the suction unit should be black tabs that pull out slightly possibly with help of flat head screw driver, then wheels should slide off, and have access to screws to remove top cover and eventually reach motor. From there its a full motor servicing since this machine got water in it. Most likely there is a carbon brush problem, actuator and fans need cleaning.

Check power nozzle. You'll definitely need to clean and lubricate agitator bearings, hopefully the brushes are in good shape, as its nearly impossible I've heard to find new brushes for these.

Once running these machines clean very well, terrific suction.

Thanks Durango159, I'll try to open it up when I get some time. Do you have any idea as to how to service the motor? What type of lublacant should I use and where do I order some carbon burshes? Does a wiring diagram exist?

I've been successful with oil and grease for Hoover agitator bearings. I clean them first. Remove any visible dirt and hair, rinse then rub over a scrub brush with some soap- usually Dawn is what I use. Then add oil to both sides spinning it in. Some others may beg to differ but for me this has worked quite well.

Opening up the top cover on a Dimension to check the bag check indicator and cord reel is about as far as i got with one. Never needed to service my motor-- If it's not broken, don't fix it.

However with most typical suction motors tap, tap, tap along pressed seem where fan cover is pressed to motor. Loosen and slide off cover. Carefully for your sake, and fan, use socket wrench to remove bolt.

I have attached a diagram, if its not your exact model go to: to find your exact. But I'm pretty sure the one I have is yours.

The brushes look fairly standard for Hoover. They come in a plastic case with spring and carbon brush attached, extremely similar to PowerMax/ Windtunnel canister motors. Should be able to get those for around $20 total I bet.

Have you serviced a Hoover Quadraflex Powermatic before?

Remove chrome wands, flip over, remove 2 screws. flip over. CAREFULLY remove top cover pulling from back to front-- cord goes through cover. This is a definite care spot and one thing I don't like about the repair on it. Just adds extra wear to power head cord.

Belt number is 38528-011
The agitator end caps unscrew by hand-- hold both ends and turn. the the rod should come off with one bearing still on there. Firmly grip rod-- rubber glove may be useful for traction and unscrew other end cap to remove bearing. 2 rows of brush strips can slide out for cleaning. the belt pulley end with 2 rows of about 1.5" brush pulls off as one round plastic piece. From there from what I remember you can pull off the belt pulley side of the agitator to be able to pull out the other side of brush strips. Kind of a neat setup.

The motor is about the same one they've been using since that time to now. It's about the same design as a PowerMax/ Windtunnel power nozzle motor.

The last time I serviced one of these was about 13 years ago, so its a little vague but mostly there!

I don't actually have access to the Hoover right now. It's in our new house's garage which we are not living in at the moment. I should be able to get to it before the end of September, that is if the house is ready.
