Electrolux model 86

[vacuumfreak]

Hey guys.... I have a little bit of a problem. I turned on my model 86 lux today, and it made a little bit of a roaring noise and had a bit of vibration when it started up and shut down. It runs fine, but it only makes this noise when it starts up or shuts down. Does anyone have a solution to this problem, or could tell me what caused this?

Thanks,
Daniel

Daniel....

check the bearing on either end of the armature shaft.....check for any end play and lateral play. Separate the motor out,  put electricity to it (don't shock yourself!) and watch the armature....I think you'll see your answer. Bearing will do what you describe when they run dry/dirty as well.

There is only one bearing on those motors and its probably the problem. If you have a bearing puller its not hard to replace it though. You can get them at Aklands for 3 or 4 dollars.

Then....

there has to be a sintered bushing on the other end...something.

The top end of the motor is a copper bushing. You rarely ever replace that. It just has to be oiled with something like 3 in 1 oil. Its packed in fiber that holds the oil so its continuously lubricated.

Again.....

Some are dry lubricated some are wet. 3 in One oil is not the best, but they do make an 20wt oil in the little squirt cans specifically for small electric motors. Comes in a distinctive blue & white can so as not to confuse with 3 in One. Mars Turbine Oil is better yet. Dry lube sintered bearings need to be replaced with same, as it's nearly impossible to imitate the dry, impregnated process they use. </a></strong>
