The are quite easy to fit on a henry. you eather have the HVR200 which is single speed and single stage motor from about 2002 -2003 or you might have the HVR200-22 with push button and rocker high/low switch from 2004-2006, that is a two stage and two speed motor, the carbon brushes should be available on a website such as espares but I would deffinately replace them if they are quite low.
Hope this helps. |

I don't think it would be a short in the armature windings, as that's rare to happen to Numatic motors. But if the brushes are running down to the springs, like you said, it could just be a simple fix. They only cost about £10, so it's not a big loss if you change them and it doesn't solve the problem, as they would need replacing soon anyway. Luckily Numatic's are really easy to work on, with lot's of parts available cheaply.
Good luck on getting it sorted! - Joe |

That's superb thanks for the info' all. I've noted the motor type etc & have priced up some brushes so will be getting some & attempting to fit them. I've never worked on a vacuum before so wish me luck ! Many thanks- Dave |

Be careful prising the end caps off to get the springs out, I've snapped a few even whilst being very careful. A blob of epoxy normally holds them in if so. |

But the Henry HVR200-22 with new switch bank have carbon brushes that you can buy as a whole piece in a little cartridge type thing so you just unscrew the holding screw and through the hole cartidge with old carbon brushes away and then you just slot in the new ones and screw them back in.
Beko1987 - I hear you, the carbon brush doors are terrible for snapping off on a Turbopower 1 I hate bending those doors back as they usually always snap off, so I don't do it :P If I want to disasemble the motor I normally carefully pull the armature straight out and when it comes time to put the armature back in I put the carbon brushes in their slots and hold them back in their slots simultaneously with tiny flat head screw drivers and push the armature back in place then release the srew drivers so the brushes are back on the comutator, it is not the easiest way but it is the safest way on those little doors, when a new carbon brush holder is £8.79 (each) I don't want to risk snapping them :P |

The actual holder for the carbon brush should stay in place, if it is a carbon brush and a little spring on the end of it. I think on those type motors you have to bend back a tab that is holding them in place or it may be a piece of metal that screws down onto it but anyways you either unscrew or bend back the little tab and then it will just shoot out of there (as the actress said to the bishop) you just pull out the old brush (what is left of it) and spring, chook it out, push the new brushes into the carbon brush holders and bend back the tab (carefully) or screw down the piece of metal which ever it is, you will see when you get yours open but I am willing to bet 90% it will be a tab you have to bend. By the way, you have the 2003 push button, single speed, single stage motor which is 1100 watts. |

Excellent, thanks for the tip Alexhoovers94, it'll come in very handy. The info' about the machine itself is great too, as I find that sort of stuff fascinating. Many thanks - Dave |

Hello I might give the switch a try & see how it goes. If anyone has any other thoughts on what I might try too, please give me a shout. Many thanks Dave :-) |
