It sounds like its time to replace the bearings and motor carbons.I find that most machines of this age are in some need of maintenance,The parts shouldn't cost much and your machine will run like new again. |

Some minimal blue sparking is normal where the carbon brushes meet the commutator. I light dressing with an abrasive commutator cleaning stick should clean any residue from this area. You might also want to check the brushes to make sure they are free to move against the commutator under their spring's pressure as they wear. Bearing grease can sometimes dry out, not necessarily from hard use but from age, putting an extra load on the motor which might cause some extra sparking. If none of these remedies cure the problem, you might have the armature checked by an electrical motor shop or vacuum cleaner dealer. Here's hoping this will help you. --Bernie |

I'd be sure to oil or grease the motor fairly soon. WD-40 might be good at unsticking things, but I've heard it is not a really good lubricant. Glad your problems are solved, and happy Hoovering! |

I remember that pale lime vac from my childhood Wish you were closer I got a Merz 83 500 SEC that could use some loving care. |

OK....I would recommend VACUUM CLEANER BEARING GREASE because it is the proper viscosity for vacuum cleaner bearings. You have two bearing plates on your Hoover, one on the top and one on the bottom of the motor shaft. The bearing plates are hollow. It takes a special Hoover tool to force the bearing grease into the bearing plates. and you may have to remove the fan in the process. Although the bearings CAN be greased by hand, it is more troublesome forcing the grease into the bearings with your fingers. Either way, you'll find a tiny pin-sized opening on each bearing plate. It is like a tiny vent hole, which is exactly what it is. When the bearings are fully packed, the grease will ooze out of the hole. Remove the carbon brushes, check them for wear and make sure that they are free to slide in and out of their retainers under thier spring's pressure. Get a "com" stick or a fine piece of emery cloth to clean the commutator as you spin the shaft by hand. The commutator should look a shiny brass or copper color and be free from residue after this is done. DO NOT rely on WD-40 for bearing lubrication, although it may temporarily help to revitalize any remaining dried up grease within the bearing plates; it is only a temporary measure! WD-40 is NOT a sufficient lubrcation for sustained use and long motor life. WD-40 or light sewing maching oil is fine for sqeeky wheels or other sticking machanical parts but not for the motor. If you follow these directions carefully, this should get you going. Hope this helps. |
