Question about Kirby Heritage II Vacuum

Carbon Brushes wearing out quickly on Kirby Heritage II

I have a Kirby Heritage II vacuum cleaner that was repaired a few months ago.   The problem was that the carbon brushes had worn down, thus the motor would not operate.  
Now, a few months later, the vacuum was in use when the motor started to die and finally stopped.  I opened up the vacuum and noticed that one of the carbon brushes appeared to be worn again -- so I wasn't getting good conductivity across the motor.   This appears to be suspect that the new carbon brush would wear down so quickly.
What could be wrong with the motor, and is it really worth fixing?

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)

How to remove a Kirby Heritage II Armature


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.

Got this Heritage II Kirby vacuum that when running for about 5 minutes it will stop and smells like burning from the motor. Is the brush out needing repair or something else.


It sounds as if the carbon brushes in the motor are badly worn and will need replacement. DO NOT operate the vacuum in this condition or you may damage the motor armature beyond repair.

Motor light comes on but motor does not start on Kirby Heritage II


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.

My Kirby vacuum cleaner will only run for a few


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 .

Hi There
I have got a Kirby 2 HG vacuum cleaner which is around 20 years old now. It was going really well until last week when one of the capacitors which are connected to the brushes blew up. There is two capacitors one for each brush. One of them completely blew to bits and the other one is still intact. My question is are they the same size and where do I get a new one from.
I know it is an old machine, but I would like to fix it and get it going again. Any tips???

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
Yes, I think you are referring to the carbon brushes for the Kirby II HG and it is a good idea to change both of them @ the same time to be able to wear the same. Having 2 different sizes could affect the motor performance and the carbon brushes / capacitors and it would wear uneven. If you are referring to the brushroll, replace it with a genuine Kirby brushroll and to do a belt change every 4 to 6 months. Please feel free to contact your local vacuum cleaner dealer in your area & in the yellow pages, if not call the factory or the website listed below:
