The adjustment knob on the hood of the machine is a plastic "arm" that prevents the belt tensioner from tightening up the v-belt so that the roller will stop or start. If the knob is adjusted while the handle is back, it can break the plastic arm off and then the function will not work. This knob should only be adjusted with the handle in the upright position. Usually, if the arm is broken, the roller will still turn when the handle is lowered and will not turn off when the knob is selected to the bare floor. If the brush roll will not switch on , it is usually a problem with the belt(s). You should replace the belts yearly. They can look fine, but be worn out.

I took the roller brush off to clean it,replaced it now it will only spin in the recline position.l put it in the vacuum position and it stops. I have a DC 14 animal.


I'm not sure what you mean by recline and vacuum positions. Normally when the handle is in the upright position to use the tools and hose the brush roll does not turn. When you recline the handle into the floor vacuuming position the brush spins. If you were able to remove the brushroll an reinstall it the brush roll belt is likely very stretched out because otherwise it is very difficult to put the bush roll back in with out using the belt change tool. This can cause the brushroll to spin but stop spinning when when it hits the carpet because he belt is too loose. Belts must be very tight to spin the brush roll in he carpet. There is also another belt that you can't see under the clutch cover. It becomes stretched out also. The belts need to be replace every few years as do any stretch belts. The hard part about changing belts on your model is they are inside the clutch, it's easier to replace the whole clutch. If you have any questions or need any of the parts or belt change tool please email me at thatvacguy@gmail.com.

Shark nv350 making loud noise when switched for carpet


HI, it's Jim from Crucial Vacuum!

If your Shark NV350 vacuum is making loud noises when switched to carpet then there are a few parts of your vacuum you can check to resolve the problem.

First thing let's check your vacuums canister. The idea is to prevent clogs and anything that will obstruct your vacuum from operating properly, and running smoothly without noise. You'll want to empty your canister after every use.

Secondly, let's check out your brush roll. Is there hair wrapped around the roll itself, or any noticeable debris that would prevent the brush roll from turning? If so remove it and manually rotate the brush roll to help unearth any hidden clogs behind the roll.

While you're examining your vacuums brush roll take a look at the belt as well. If the belt isn't wrapped around the brush roll properly this could be causing the noise. The belt should have a good bit of tension on it in order for the brush roll to turn properly. Your vacuums belt should be replaced roughly every 3 months. So be sure it's on properly and has a good bit of tension.

The beater bar on the dc51 will not work what do I do


HI, it's Jim from Crucial Vacuum!

If you're having trouble with your DC51 vacuums brush roll here are a few things to check for to resolve the issue.

Be sure that your Dyson DC51 is reclined and not in the upright position when testing the brush roll and if you have the option set the vacuum to 'Carpets' and not 'Hard Floors'

Look for noticeable debris stuck in the brush roll such as hair, or strands of carpet fibers. Remove these blockages with a razor or scissor.

Lastly, apply WD40 to the bearings of the vacuum to help against any resistance the brush roll may be experiencing. When a brush roll hasn't been replaced after usage, the bristles get worn and

How do I replace a belt on an upright kirby?


First, go to a vacuum store ("sewing and vacuum" shop in some places) and purchase the correct belt. You unlock the rug plate by unhooking two latches on the rear of the nozzle. The rug plate is the steel item which rubs on the carpet and locks the brush roll in place. Just look on the bottom and you will see two steel levers which you need to move. You then lift out the brush roll: pay attention while you do this to see how it comes out, as that knowledge will help when it is time to put it back in. You then place the new belt over the brush roll and then replace the brush roll. On my Gsix, one of the plastic brush roll ends is larger than the other. The roll will only fit in one way, so flip it around if you can't get it to smoothly slide in place. Maybe it is the same on your G4.

8955 Upright Vacuum: How to change belt?...


Be sure to unplug your vacuum from the electrical outlet before proceeding!

-Turn your vacuum upside down so that the handle is resting on the floor and nozzle portion is resting on a work bench.
-Remove the 2 phillips screws from the metal bottom plate and set the bottom plate aside.
-Look at the right side of the brush roll. You will see a bent metal rod that attaches to the brush roll end cap. This is the clutch rod that allows your brush roll to spin or not depending on the position of the carpet/floor switch on the top of the nozzle. Pull this rod out of the brush roll clutch only. Leave the switch end of the rod where it is and just let the rod rest there.
-Pull the brush roll and old belt out and dispose of the old belt.
To install a new belt; put the new belt on the motor shaft first, next put the other end of the belt over the end of the brush roll and stretch belt and brush roll back in to place. Notice that on the brush roll end cap opposite of where the clutch rod goes, there is a metal piece with a slot cut into it. Be sure that this slot mates with the plastic stop in the nozzle so that the end cap cannot move.
Snap the clutch rod back in place and rotate the brush roll by hand to make sure the belt is not pinched.
Replace the bottom plate.

How is the V-belt tension adjusted (Hoover Model U6439-900)or how do I know if the tension is correct? There seems to be a lot of "play" in the belt and I'm wondering if that is the reason the brush roll...


The V-Belt is not adjustable. There are two ways the belt has no tension: (1) when the handle is upright, a mechanical lever takes the drive tension off the belt, and (2) the brush roll lever setting you described. The upper handle would have to be in the floor cleaning position to check the belt, not in the storage position.

Kirby g4 vaccum


please clarify what you mean?
Do you mean motor bearings or brush roll bearings?
brush roll bearings can be adjusted to lower the brush closer to the carpet when worn.
to do this remove the front brush assembly, there is usually a sticker below the belt hole showing RED = POSITION 1 HIGHEST (ie a new brush roll)
GREEN = POSITION 2 MIDDLE (brush part worn)
BLACK = POSITION 3 LOWEST (brush fully worn)
At each side of this there are 2 clips unlock these and remove the bottom cover.
Release the belt tension by rotating the belt release at the front.
Before removing the brush roll, at each end of the brush roll there is a grey plastic bearing carrier (Square at the ends) MARK this with a pen or marker just so you know the original position, also look closely for the coloured markings as indicated above or numbering 1,2 or 3.
If RED or "1" is showing you need to remove the brush roll by pulling it out and rotate the endcaps to Green or "2" and re-insert the brush roll, If Green or "2" is showing then rotate the endcaps to Black or "3" and re-insert.
If Black or "3" is showing then the brush roll is worn and cannot be adjusted any more, fit a new brush roll and insert with RED or "1" showing.
To re-attach the belt, move the belt to the middle of the roll and rotate the belt knob at the front ensuring the belt engages with the hook on the inside.

Hoover WindTunnel Self-Propelled V Belt


when you released the end to slide the new belt on it allows the tension roller to slide into the wrong position. Remove the top so that you can see the roller, at the left side of the roller mechanism there is a screw, loosen it enough to allow the roller to return to the correct position.
good luck

Brush Roll belt won't engage on WindTunnel self-propelled


When you had the brush roll off, did the ends turn freely? If not then the brush won't turn and the belt will just slip. You would have to replace the brush roll if either of the ends are frozen. Other then that you would have to remove the top cover to see if there any broken parts, there is a spring loaded asm, it has a black wheel that will push the V belt when it is in the carpet setting and the handle is in the down position, it could be jammed so the roller is stuck.
