Stand vacuum up and with it plugged in. Rotate knob between carpet and bare floor and back 5 times leaving it on carpet when finished. Rotate vacuum back from upright position and lay vacuum on the floor, rotating it onto its side. Turn vacuum on.

Hi If your Dyson has a brush protection design - i.e. roller bar on the top of the hood on the left hand side then the DYson can't be repaired by you- serviceman or professional care can replace it.
However if the Dyson doesn't have the roller bar on top of the hood, flip the machine over so that the beater brush is facing upwards, locate three/four screw heads that can be undone with a coin and remove the sole plate assembly. This should give you a clean view of the brush bar, drive belt and dirt channel. Ensure everything is clean espcially if the brush bar has lots of hair or threads tightly corded around. Then locate the drive belt and check to see if it has snapped. Grasp the beater bar gently upwards and the belt and brush can then be removed. Fit a new belt on carefully and check the tension as it will be tight.

Apparent common failure is that either the thin yellow and or blue motor drive wires that run from the LH side of the vacuum where the "control board" is located down into the hinge / ball area become stretched and then fray and eventually break. Happened to my Dyson twice. First repaired under warranty, second took about 20 minutes. You need a Torx screwdriver to remove the LH panel ( 4 screws) and also an access panel (2 screws) at the side of the ball which permits access to the blue / yellow wire connectors. I replaced with a new wire and connectors having fed the wires through the access hole making sure sure enough wire was available for the movement of the handle. Also ensure that when the covers are replaced they do not trap any wires underneath.

Greetings,

I will attempt to walk you through the belt change on your Riccar 8955 upright vacuum cleaner. I have taken pictures for you for each step to ensure that it's done properly. What you'll need to have handy for this repair;

- Phillips Head Screw Driver
- Riccar 4000 / 8000 Series Belt
- Riccar 8000 Series Roller Brush With Clutch Assembly (only if the brushes have worn down, not necessary if brushes are still long)

Step 1: Make sure the vacuum cleaner is unpluged, and turn the vacuum cleaner upside down so the bottom plate is upwards. It's easiest to do on a work bench or counter top.



Step 2: Unsrew the two metal screws on the metal bottom plate with your Phillips head screw driver, and remove the bottom plate from the vacuum cleaner so the belt is completely exposed with the roller brush.

Step 3: Remove the belt guard that sits to the left of the roller brush, and is a metal part that protects any dirt & debris from going over to the belt. Here's a picture of that part being removed;



Step 4: Remove the Rug / Floor actuator arm from the clutch on the right hand side of the roller brush. Simply pull the metal actuator arm to the left of the brush and out of the circle that it sits in. Here's a picture of that;



Step 5: Once you have removed the actuator arm for the clutch, as well as the belt guard, lift staight up on the roller brush and remove the roller brush from the vacuum cleaner:



Step 6: Once you have removed the roller brush, and the old belt from the vacuum cleaner, take one new belt and wrap it around the metal pin in the back of vacuum cleaners agitator housing. Here's a picture of where that pin is located with the belt wrapped around it;



Step 7: Once you have the belt wrapped around the metal pin (this is the shaft to the motor that actually spins the belt), but the other end of the belt through your new roller brush;



Step 8: There is a specific way that the roller brush has to be inserted. If the roller brush is not put in properly, this can cause all sorts of problems including the brush not spinning, and continously having to replace belts. You can see on the end cap of the roller brush (the right side where the belt rides) that there is two little teeth that protrude out of the end cap as well as an indentation on the opposite side;



Step 9: With the roller brush inserted through the belt, posistion the two teeth facing downwards. You can see in the vacuum cleaner where the roller brush sits, a little groove down inside of the housing. These two teeth need to straddle that groove. Also make sure that the little ring, or circle that the clutch actuator arm sits into, is facing upwards completely. It should be directly on top of the two teeth. Stretch the belt using the roller brush as leverage down into the agitator housing of the vacuum cleaner, making sure that the two teeth are facing downwards straddling the little groove. After the brush is back into the vacuum cleaner, take the metal actuator arm from the rug / floor switch, and insert it back into the metal ring (or hole) on the roller brush;


Step 10: Replace the metal belt guard that rests to the left of the belt. You'll notice on the belt guard that there are two little 90 degree notches on both sides. These notches need to face towards the belt or to the right. Here's a picture of the belt guard being put back into place;





Step 11: After inserting the belt guard back into the vacuum, turn the vacuum cleaner over so the top of the agitator housing is facing you. Change the the rug / floor switch from bare floors to the carpet setting, and the turn the vacuum upside again so the brush and belt are exposed:



Step 12: With the vacuum set to the carpet setting, pull the belt forwards to ensure that the brush is spinning freely. If the belts do not spin freely, repeat steps 2-10.


Step 12: There is a flap that can be opened after the metal bottom plate has been removed, that will give you more access to the motor shaft. Make sure that this flap is closed;



Step 13: The last tricky part can be reinstalling the metal bottom plate. There is a little lip on the front of the vacuum cleaner that the edge of the bottom plate has to slide under for it to be installed properly. A lot of people just install the bottom plate over top of this lip, and this prevents the brushes from hitting the carpet as low as if the bottom plate is correctly installed. Here's a picture of the lip with the bottom plate in the backgroud;



Step 14: Slide the metal bottom plate into the lip on the vacuum cleaner, and fasten the screws back into the bottom plate to secure it. The lip is a little tricky, but after doing it just once, you'll have no problems in the future changing your belt.

Here's a picture of the bottom plate installed INCORRECTLY with the bottom plate over top of the lip;



Here's a picture of the CORRECT way to install the bottom plate:

I just fixed mine. It took me all of 10 minutes. Pull the brush out. Stand the brush on end on the edge of your study work bench/table top. while holding the brush vertical( on end) take a small phillips screwdriver and tap using a hammer on the metal pin you see in the middle of the brush. Keep tamping and the whole assembly will come apart. What you will have then is a long metal shaft, 2 bearings(they are acutally skateboard wheel bearings same number same make). Clean the gobbed up hair with a razor blade and then reassemble by tapping back together. The bearing wont be worn out because they are way too tough for a vaccum. We used ride down hills on them! a ten minute fix wow and you wont have to drive to vacuum shop and spend $$ and time
