Question about Hoover Commercial Windtunnel C1705-900 Bagged Upright Vacuum

Open Question

I need the wiring diagram for the motor.

I have an old Hoover Commercial C1705-900 that needed brushes and the armature cleaned up. I completely dis-assembled the vacuum and took all the parts except for the wiring and filters and motor and ran them through the dishwasher. I found brushes and installed them. Now, I realize that there are 3 terminals on the motor. I have the white wire with the other 3 whites, the black wire with the red to the switch and the green to the ground wire. It appears that the black from the headlight goes to what I would call the center terminal on the motor, the brown from the switch through the thermal limiter to the other top terminal and the white wire(s) to the lower terminal on the same side as the black headlamp wire. Is this correct? Help before I toast the motor.

Need help installing belt on Hoover self propelled upright vacuum

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Hoover Ultra U6430-900 Wind Tunnel Bagged Upright. The best way to install the belt on a Hoover to replace one or both of the belts @ the same time for the best cleaning. The average belt change is every 4 to 6 months for best results. There is a tool that looks like a screwdriver that has a right or left angle on the end that serves as a belt puller and to hook the belt(s) onto the brushroll 1st and then take your puller and then pull or stretch the belt onto the motor pulley. So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.

Check for the front panel duct located on the lower tank front. this is the part you need to remove to attach the hose. also check to make sure the lid is on and secure on the lower tank. remove the lower tank and look on top of the motor cover toward the left front corner you should see a round black gasket on a pipe. if not there, this will cause poor suction.

Solution for Hoover SteamVac (F7452-900) brushes not spinning
Uses the turbine model and same solution would be similar. Root cause is simply the main gear attached to turbine becomes stuck. This problem should not happen as often as I see other people also having this problem. Must be a poor design on Hoover’s part. It takes about 30 minutes and a Phillips screw driver and wrench. Pretty easy, just have to remember what screws went where.
Remove brushes, and front suction cover
On the bottom of the machine:
Remove the 4 screws behind brushes which attach the top faceplate
Remove the 2 screws from base in the sunken holes
Remove the two long silver screws from base which connect all the way to turbine assembly
Stand machine upright
Remove the floor select switch handle
Remove 1 screw near the center beside the intake hole
Remove the 2 screws over the rear wheels
Remove faceplate cover, the front will need to be gently pried over the clear plastic part, be careful about the upright disengaging lever under faceplate, move it under the metal wire
Remove the 2 screws in the front of the turbine assembly
Remove the 2 hoses on either side
Disengage the bar on the floor selector switch
Pull out the turbine assembly
Remove the 4 screws and 3 clips to separate the assembly
Remove the filter (which is most likely clean since, cleaning this is the manufactures only solution)
Remove the large white gear and with a wrench remove ball bearing
Remove other large white gear
Note that the metal gear attached to turbine will not move (this was my problem), with a wrench gently grab metal gear and twist free. Spin turbine to make sure it moves freely.
Put everything back together again and you should be good to go.

I do not know what price you have, but it depends on the condition of the vac, compared with new exact replacement.

The brush system on this model has a poor engineering design in that the brushes are running off an air turbine, which uses a steel bushing to spin the turbine which gets rusty from the moisture when the machine is being used. No long term solver. I would replace the machine with a Dirt Devil Platinum Force model

Brush roll won't turn only a few times


Shane:
Unplug the machine and lay it on it's back with the handle release in the release position (the vacuum head should be laying flat also). Remove the foot plate from the vacuum head. Manually turn the brush roll (called a beater bar). The beater bar should turn fairly easily and the belt should turn the motor armature shaft (now would be a good time to check the inside surface of the belt for grooves or damaged spots which would cause the armature shaft to slip on the belt). If the beater bar has too much resistance to your turning it, I would suspect that the bearings at each end of the beater bar are fouled with hair, carpet fibers and string. Remove the beater bar from the machine and manually spin the motor armature shaft (where the belt contacts the motor) to see that the motor armature shaft spins freely. Remove the bearings from the end of the beater bar (they won't come off easily so you may have to use a prying tool such as a screwdriver). Try to spin the bearings. If they are fouled, dribble some rubbing alcohol into the bearing (I use a spray bottle... it's much neater) and turn the bearings while keeping them soaked with alcohol until they spin freely without ratcheting. Drop some 30 weight engine oil into the bearings until they are saturated, then clean the outsides of the bearings with a clean rag (no alcohol) until the outsides of the bearings are completely dry and no oil drips out of them (don't want the oil to attract dirt). You'll probably need to replace the belt. Reassemble the machine and it should work for you.

Electrolux Vacuum Cleaner Epic series 3500SR: The motor runs but not at full power and then quits then will start again.


Check the piece of flex hose between the vacuum body and the power nozzle. This will sometimes get a blockage in it, causing varying motor speeds.
You can remove the tube by grasping it firmly and pulling from the power nozzle. Then twist clockwise to remove it from the vacuum body. Clear blockage with a wooden spoon handle or similar blunt object. Insert tube into body and twist counter-clockwise until tight. Insert other end into power nozzle about an inch, or until it stops.

Another thing to check is the foam filter at the bottom of the bag well. Remove and replace if necessary. If a new one is unavailable, the vacuum can be used until you get a new one. Or rinse the old one out and allow to thorougly air dry before using. Also check the screen covering the motor intake and clean if needed.

Also, if your machine is fitted with a afterfilter on the lower side of the tank, this may need to be removed if dirty.

Our Hoover U8172-900 brush motor is not working. Do you have a wiring diagram so I can determine if the motor circuit board is the problem or the motor?


No diagrram is necessary unless you have dismandled.
Check if the brushes are touching the mtor commutator. If not you can easily remove both the brushes and polish the surface evenly .Insert only after cleaning the motor commutator till the copper shines.
Use can check for the continuity of the brushes to show that the armature is working Ok.
Now check the filed winding. Both the windiings must snot show any leak or short to the body. If so the motor is fault.
If field is ok with the resistance check then check for power supply to mtor when switch is triggered . If not check cord and switch.
Hope this tip helps.

Removing the pulley from the shaft on a hoover c1433 to replace the fan or impeller.


Removal of the pulley requires extreme care. There is a small opening on the side of the black motor housing to allow a special tool (or a screwdriver) to fit on a slot on the armature to keep it from rotating while the pulley is unscrewed. You MUST NOT touch the magnet wire on the armature. If you nick or break it, the motor may fail.
The only other method requires the motor case to be seperated to permit you to hold the armature while unscrewing.

Need to replace motor brushes on Kenmore canister vacuum 116.25914503 - Getting lots of arcing at brush ends. Need tear-down steps to get at the brushes.


If you can see the arcing you are likely in the motor housing. The brushes are specific to the motor depending on RPM. Most brushes and motors in Sears units are supplied by AMTEK Lamb. The color on the plastic housing and stamped model # on motor will help identify the correct carbon brush, however new brushes will NOT always solve your problem if the motor is arcing.
If the armature is worn like an apple core or if the lines between segments on the copper commutator are gaping and not parallel you will need a new or rebuilt motor.
If brushes are properly removed there is a tiny flag terminal which will slide out of most brush housings where the wire meets the brush itself. New brushes are best installed after dressing the armature surface with a fine carbarundum seating stone or very fine wet dry sandpaper and then the motor is run in at half speed at reduced voltage.
|There is usually a hold down clamp over each brush to seat it and a lock tab underneath to align the new brush.

My hoover dual v steamvac make loud noise and sparks


Be careful. This could be a shorted wire inside where the motor is. If there is sparks , something is exposed and touching. The motor also may be ready to give out. Unless your daring enough to open the whole thing up I would bring it to a shop or replace it.

Good armature maybe needs new brushes


You can replace the carbon brushes and most repair shops should have them. Also tho, the armature could be causing the problem, if you put in new brushs and it still arcs badly, then the armature is bad.

Thermal Protector activated and won't turn off on Hoover Em upright bagless


been there... done that. Vaccuming fine powder can interfere with contact of the brushes against the armature of the motor. You can turn it on and off all you want, but if the brushes have a coating of fine powder on them the motor won't run. If there's any way to "blow it out" with something like compressed air, then spin the motor by hand (with the unit UNPLUGGED) a few times, try that. If the motor starts after plugging in and turning it on, it was most likely dirty brushes.
