Belts for Hoover Vacuum (Wind Tunnnel)

Very happy as it fit well and performance was excellent. A little over a month again, I purchased a similar belt from a competitor, which did not perform well , thus replacment necessary. Noted that belt was made in Mexico. These belts were made in …

Belts that are too tight put an excessive load on pulleys, shafts, and bearings. Excessive belt tension will also wear out a belt quickly. Proper belt tension is 1/2 inch of sideplay both ways.

The brush roll or its bearings may be clogged with hair, threads or dirt. Make sure they are clean and the roll spins. The belt may also have slipped because it was loose. Check the fit of the new belt when it is installed.
Many of these belts look very similar, but there are differences, and if you try to pick the correct belt just by how it looks, you could very easily end up with an incompatible Bissell vacuum belt for your model. Along with this, some vacuums use multiple internal belts for different functions of the vacuums.

The last time I sewed with my Necchi the tension was fine. Today when I threaded my needle, the thread felt tight in the upper tension dial. I tried re-threading the machine several times, but it didn’t help. Now the parts of the tension dial are all loose and wobbbly and I have no upper tension. Doesn’t matter what the dial is set on. The tension dial appears to be broken, but I don’t know how that could have happend since I store it in a case.

Belt tension adjustment
ANSWER : If you are looking at the belt while the vacuum is in the upright and locked position, the belt will be loose. The idler removes tension so the brush doesn’t spin while you walk away and put heat marks in the carpet. Hit the lever that allows you to move the handle low, like you are vacuuming under the bed, and the belt gets tight.

I just had this machine delivered yesterday (Janome Magnolia 7330). When I sew a straight seam (all I’ve tried so far) I get loops at the underside of the fabric. I adjusted the upper thread tension, but that did not help. In fact the loops got larger as I increased the tension. My thought is that I don’t have the machine threaded correctly. Thanks!
ANSWER : Your problem is in the tension adjustment. also check the stitch lengths.

I can see the height adjuster under my Bissell pet hair eraser vacuum, but it doesn’t adjust. The parts don’t look like they’re touching. It’s been iffy since I took it out of the box. Now it doesn’t adjust at all. Used only five times. Looks like I should be able to fix it myself. No local repair available. Could you help please?
ANSWER : Http://uk.bissell.com/images/UserGuides/3920E_508.pdf
.
.This is the pdf manual. If you look at page 12 you’ll see that the bottom of the machine has been pictured. Between the middle wheels near the brush (where arrows 4 and 2 are) you’ll find that the adjuster bar has a sprung mechanism. Now this is easy if you have time! If you take off the or just inspect the bar, check to see that nothing is clogged behind it. If it looks fine, check with your other hand by moving the rotary dial a couple of times and your other hand pressed down on the central bar between the wheels – if you can feel that the bar is moving whilst you turn the rotary dial then it should be working. Sometimes the spring that connects the dial to the bar can loosen and this may well have been the case. If you can unscrew the assembly do it gently as it will pop up to see if the spring has been put in place and then carefully put everything back together.
.
.Some uprights don’t allow the height adjuster to adjust whilst in the upright position though but if it doesn’t adjust at all then the spring has definately moved.

Height adjustment not adjusting
ANSWER : The height adjustment wont engage unless the handle is in the down position. Not knowing this led me to overturn the hight adjustment knob.
.
.Step on the handle release, pull the handle back and lay the vac on its side. Then you can get the knob and the plate back together again.
.
.BTW, the reason I had this problem is because the front brush slows dramatically when using on carpet, I thought it was set too low, and turned the knob (in a manly fashion, putting it past its limit). Still working on that one. After inspecting the belt, looks like one worn and cracked spot gumming up the works.

How do you adjust the tension of the v-belt on the u6630-900
ANSWER : Hi! I’m not so familiar with this model, but I believe the V-belt is only under tension when the brush roll  control is in the “HARD” or “OFF” position. I’m not sure what the exact mechanism is, but I suspect that moving the control to the “ON” position is what places the belt under the correct tension and thus drives the roller.  Please let me know if I’m right!.As for your other point, not sure what you mean by the “hood assembly cover” or why you might want to take it off. If you can clarify, I’ll help if I can.

Belt tensioner overheated and doesn’t keep belt tight enough
ANSWER : Looking at the owner manual, there is no tensioner assembly.
If the motor is fixed in place and not loose, then you either have the wrong belt, or the brush roller is not properly installed, or the brush roller is worn out where the belt goes around the brush roller.
