Fan replacement I found the part to replace my broken fan. I've remove many screws, but I can't remove, what seems to be, the obvious plate to get to the broken fan.

Remove the bottom plate screws & bottom plate. Remove the screws holding the motor and fan assembly to the nozzle housing. Remove the screws Holding the fan housing to the motor to gain access to the fan. Remove the bolt holding the fan on the motor shaft to remove the fan.

First remove the handle, next remove the screws attaching the cord, and switch trim plate. The small screw and knob on the handle pivot must be removed to remove the switch trim piece - insert a flat screwdriver into the small slot in the plastic and pop the trim off to expose the rear motor shell screws. Remove the four screws holding the upper motor shell in place to expose the fan housing screws. Remove the five screws holding the fan housing in place, noting their positions. Pry the fan housing off to expose the fan. Hold the fan in place while turning the belt pulley CLOCKWISE to remove it. If the armature turns, it must be held in place with an open end wrench (about 9mm). There are flat spots on the armature just in front of the commutator bars. Pull or pry the fan and associated washer off the armature shaft. After replacing the fan and pulley, put a bead of silicon sealant on the fan housing and replace all parts in reverse order of removing.

Hello,

Follow the steps below gradually:

Remove your vacuum's power head by first switching the carpet height adjuster to its highest setting. Turn the belt lifter, making sure that the two red arrows pictured on the lifter are pointed at each other. Disconnect the head, and take it off.

Remove the bag and handle by first unsnapping the handle by pushing a button on the back of the handle located near the base of the handle. To take off the bag, place your hand on the plastic located at the bottom of the bag, and pull it off.

Remove the metal body by simply unscrewing the four medium-size screws that are now visible because of the power head removal. Once the screws are removed, you can easily lift the metal body right off.

Remove the front fan cover plate using a screwdriver to remove the screws located on the front of the plate. Once they are removed, the fan plate should pull off. If it doesn't, gently pry it off by wedging the screwdriver between the plate and the base.

To remove the fan, clamp a pair of vice grips on the pulley to keep it from moving. Attach a 9 mm end wrench to the motor shaft; this will ensure that the shaft won't spin. Turn the vice grip, which will un-thread the pulley, and pull off the fan.

Integrate the fan, and put the vacuum back together. Plug it in, and test it to make sure it's working properly.

Good luck.

I have the Bissell Big Green model 1672 and have used it for many years. Recently, the fan or suction blower began to emit a burnt smell so I shut it off. I had difficulty figuring out how to dissemble the top motor unit. Here is what I found.

Don't pry up on the very top disk, which is an air outlet. It will only break off and won't allow access to anything. If you do break it off, drill holes through the four posts and use stainless steel screws to re-attach the disk to the plastic posts it sits on.

Now, beneath the air outlet is the rest of the motor unit. The motor unit consists of three pieces. The bottom piece is the lid to the waste water receptacle. It is concave pointing down (lid shaped). The top piece is the domed lid for the motor unit. The middle piece is a flat plate between the other two pieces. The top of the flat plate (inside the unit) has mountings for the suction fan and the pump.

The flat plate is bolted to the bottom piece and the top piece (domed lid) is simply snapped down to the flat plate. If you take a flashlight and look inside the area where the AC cord is stored, you can see that the domed lid is a distinct piece from the flat plate. The model 1672 and 1680 (or 1680-3 if you wish) are nearly identilcal.

To access the internal parts in the motor unit, you cannot pry between bottom piece and the the flat plate because they are bolted together. But you can remove the top domed lid. To remove the domed lid, position the motor unit in front of you with the switches at 9 o-clock. Three snap-downs which attach the domed lid to the flat plate are at 1 o'clock, 2:30, and 7 o'clock. Wedge a flat bladed screwdriver or pocketknife between the edge of the domed lid and the flat plate at those locations and the lever the domed lid out and then up. The domed lid will separate from the bolted-together flat plate and bottom piece.

Wiring from the switches remain attached to to the electrical components. You will see that the AC cord has white, black, and green wires. The green ground wire connects to the fan ground at the 9 o'clock position. The white power connects to upper connector on the pump and also to the fan at the 7:30 position. Black feeds both switches on model 1672 and then a black wire runs from the correct switch to the bottom connector on the pump or to the connector on the fan at the 1:30 position.

Model 1680 has a third switch which feeds power to the floor sweeper. It has its own connection to the green ground and white power and goes through the third switch to connect to black.

If you need to replace the pump or the fan, shop around carefully. The pump, for example, can be found for $30 plus shipping, but some will want to charge you $80.

In order to replace the fan you will buy a 2 or three piece lexan fan kit containing the fan a spacer and shaft.
You must remove the carpet head and then looking from the back of the machine you will find a series of philips screws on the outer edge of the fan housing facing towards the front, several of which may be partly covered by the motor housing. You will remove the forward facing screws to allow the housing to separate and reveal the fan.
If you are lucky there will be a sideways hole through the impeller shaft allowing you to slip a nail through to help twist the saft to unscrew it while holding the fan .
The shaft will turn off revealing a threaded motor shaft with spacers which the broken fan will slide off revealing a second spacer at the back . Be sure to replace these spacers in the same order when re-assembling the unit. Secure the shaft hand tight. Post back to advise if you need further help

It is always best to have a cirtified & Authorized Service Tech or Center do the work and only with genuine Filter Queen parts and supplies. Both can be found at 800-344-1840 or in Iowa 888-637-4692

If a Authorized Tech can not come out,

1. Always unplug unit from electric outlet.
2. Remove top like you were changing filters, also the crown.
3. Remove cap under handle.
4. Remove 3 screws from SN plate then remove plate.
5. Seperate upper from lower.
6. lift cardboard piece and Silencing Filter.
7. Now you can remove the 4 screw that hold the handle.
8. Repace handle and reverse the above steps.

Hi,
I just replaced the fan (plastic) on an XL9100. I assume you got the bottom plate off (5 screws).

Undo the single screw holding the suction housing in place.

Remove the two screws holding the motor in place and gently lift the assemble up, being careful not to stress the wires. The motor and fan assembly should now be exposed. If the nut holdling fan in place is removed, the whole fan should slide right off. If it does not, try a little WD-40 on the shaft and wiggle and move from side to side. (I slipped a small drill bit between the motor fan (motor cooling fan) to prevent the shaft from turning when you remove the nut.) Be sure you turn the nut counter-clockwise to remove it.

You should now have the fan off. Reverse the procedure to place the new fan - following the directions carefully as some assemblies need a washer and "feathered" washer on the top.

Assuming everything went well, it should work.

My 9100 sucked a magnetic bearing and trashed the metal fan to where suction was weak. The new fan works great.

Cheers

How do i replace the fan blade assembly which are broken in my eureka model the boss
thank you

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
There are 2 different models of the boss by Eureka – there is a standard old style upright that the belt that the belt would unscrew from the bottom of the motor and you would have to remove the top of the vacuum cover to remove the main motor and gasket assm, and then the fan has a reverse thread on the plastic fan and you would unscrew the fan after removing the belt pulley. Then you would screw on the new fan, belt pulley, replace the gasket and re-install the motor. If you have a new style with a side mount motor you would remove the top cover, the motor would be in there sideways, un-screw the motor, remove the silver tape around the fan housing and un-screw the fan housing – same as above un-screw the fan from the motor, there is a nut on the end of the fan holding that on – (remember, the fan has a reverse thread) re-install the fan. Then the fan housing, replace the silver tape, and then screw down the motor and replace the top cover, then you can test. As always free to contact your local vacuum dealer in your area in the yellow pages or contact your Eureka factory manufacturer listed below:

Take off the bottom plate, remove the screws for the motor and fan chamber, remove motor from fan housing, remove the nut for the fan. You may have to lock down the armature if the nut is too tight. Replace fan and reinstall motor into the fan housing and reinstall.

One of 2 ways, remove the plate on the bottom, the is a clear cover covering the fan. Just unbolt the belt pulley and remove the fan. If there is no cover covering the fan, then you will have to remove the top, take out the 4 screw holding the motor and turn motor over, then you can remove the fan.
