I had to replace the fan in our vacuum cleaner and unfortunately, before I figured out the proper disassembly procedure I removed the armature from the motor plastic housing. My question concerns the proper location of the carbon brushes in the housing in relation to the armature. Do they just "float" around the commutator or is there a proper location. Are they supposed to be loose? Also I assume that the Finger spring and washer seat in the back of the plastic housing and the end of the armature rest on it. Does the finger spring go in first and then the other washer or vice versa?

The armature that holds the fan on is reverse threaded. It turns to the right to remove it. You can put a nail or nail punch in the hole on the armature and tap it gently to the right. this should loosen it enough to unscrew. There's a washer, then the fan, and a spacer that fit over the shaft.
Remember that the motor will not run unless the vacuum head or hose are properly installed. If this is not the problem, the most likely problem is that the carbon brushes in the motor are badly worn and will need replacement. A less likely problem is that the front safety switch is out of adjustment. While the light is on, remove the head and push the metal rod on the switch next to the fan inward to see if this causes the motor to run.
could be caused by bad bearings in the motor or bad carbon brushes and a worn commotator on the armature. check the cord where it connects to the top of the handle on the swivelling strain relief. usually the cord fails there .
you need to make sure the belt is on the roller correcty, make sure is at the red position when putting the part back on with the belt on the hook, push the pedal to highest (off the ground) position to ensure you put it on correctly, then turn the fixing clip thing to secure it, then once its on turn the panel around to green position, belt will be back on, once you get used to it you'll be ok,
4 possible reasons. 1 – one or both bearings are worn so armature (rotating part) wobbles as it is spinning and cause motor brushes to wear fast. Solution – change bearings too. 2 – Whoever replaced brushes – did not use some brush seating sticks to make cmutator smother and contour brushes to the shape of the comutator (not likely). Solution – appropriately install new set of brushes. 3 – Comutator is so warped that seating sticks do not help anymore – solution – new armature or turn the old armature. 4 – The fact that ONLY ONE brush was worn may mean that there is something wrong with the brush or housing. Maybe it could not move freely within the housing? I think this may be most likely cause it it may be a combination of all 4.Is it worth to fix? Hmm depends how much will it be. If this is 100+ - I’d say get newer Kirby for 300 ad enjoy the tech drive (Heritage does not have tech drive so it is much harder to vacuum with than the newer models)
As long as it is Kirby belt - you should be fine. Make sure that the shaft is clean and that you do not vacuum something greasy or wet (grease or oil will lubricate the belt and shaft will loose the grip -heat up and burn). Make sure that brush roll spins freely. I am assuming you know how to put the nozzle on properly (if you not sure - go here)

There are very simple instructions on the front assembly; however, the belt doesn't engage with the rotor, and the beater bar does not spin. When I have the front twisting section on the "Belt On" setting, it seems as though it actually disengages the belt. I see no faults in any of the mechanical parts, but just can't get the belt to go on the rotor. (I purchased this machine @ a garage sale on Saturday. It's in perfect condition.) My vacuum cleaner is a Kirby 84 Legend. Help!Jennifer Hello, I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. You can always check your owner’s manual but the Kirby has a dial on the front of the machine and you needs to dial the belt off of the fan pulley counter clock wise and to check to see if the Kirby bell housing will release @ the top so that you can remove the bell housing. If not then remove the bottom plate and take out the brushroll on one side and then slide the belt off of the brushroll. Then you can slide the new belt onto the brushroll to the center and then re-insert the Kirby brushroll with the screw heads facing downward then you can replace the bottom plate – then use the Kirby spoon or hook to dial the belt onto the fan pulley clock wise. Once that is done then plug in the Kirby and try to vacuum to see if the Kirby is picking up properly, if not repeat the process. If you have a question, feel free to contact your local vacuum cleaner dealer in your area.

Generic problem for all Vacuums How do you use and How do you use and what attachments for upholstery cleaning with the Heritage II I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Kirby has a spin brush that is round on the newer Kirby’s and it works on the suction from the vacuum and it fits on the end of the vacuum hose but it does not fit into corners very well or your can take some Kirby shampoo in the spray water bottle and use a kitchen scrub brush for the corners. Other wise you can use the actually Kirby Shampooer of which is very hard and unfriendly; the spin brush would be my selection. You can check with your local vacuum cleaner dealer in your area and also in the yellow pages. Also you can call the Kirby factory to see if they can direct you.
