Replacement Brush Bar with End Caps and Set of Belts, Made To Fit Dyson DC07 DC04 & DC14 & DC33 #904174-01

I bought this and a replacement hose for a DC33 at the same time. This took under 5 minutes to install and the hose took about 3 minutes. I read the reviews and several people claimed it took 30 minutes to an hour to install and some just gave up... Not sure where the issue was for them but mine took a few minutes and a bloody knuckle. We have used it daily for about a month or more and no problems yet. How I replaced the roller. I didn't need to replace the belt so this is just for replacing the roller: -Make sure the floor selector is on "Bare Floor" or whatever so that it disengages the clutch. This will make it much easier to pull the roller out. -Place the vacuum on a table or counter so the bottom is facing up (after you unplug it of course). -Use a coin or flathead screwdriver to turn the 3 clips holding the roller cover on and take the cover off. -While the bottom of the vacuum is face-up, have the handle and body facing away from you. Slide the retaining clip on the left that holds the roller in place so that it is completely out of the vacuum (the right side of the roller is where the belt is). This retainer clip will pop right off the end of the roller and rod if you give it a little pull. -Pull the right side of the roller up so that the retainer clip is completely out of the vacuum. You will need to use a little force as the belt is still a little tight. Use your finger or a screw driver to leverage under the belt and pull up enough to slide the old roller out. -Replace roller starting with the right side first. After you put the rod through the new roller and place the retainer clips on the correct ends, put the belt end (right) retainer clip into it's slot. Now put the other end into the slot where it belongs. -Put the cover on and use a coin or flathead screwdriver to turn the clips back into a locking position. -Use your hands to roll the roller back and forth a couple times to properly seat the belt. Now you should be able to put the selector to "Carpet" and it will engage the clutch so that the roller will spin like normal when turned on. This only takes a few minutes.

Belt replacement is not like the old days. Clutch technology is interesting. The construction of the Dyson DC33 is very well thought out. The amount of clips and screws to replace the belts was minimal. The replacement took about an hour from start to finish. A few things to note. - Remove the beater bar. The sole plate is removed by turning the three clips that hold it in place. If you don't have a large enough flat blade screw driver you can use a quarter. Lift straight up on the sole plate to expose the beater bar. There's a special tool to remove the beater bar from the belt. I was able to use a pair of needle nose pliers to pry the belt over the bar. - Take off the brush housing by trying the ends from the clips. Lift up and then remove the hose. - remove the U bend. With a flat blade screw driver, remove the cover for the clutch control knob. Use a torx T15 screw driver to remove the belt/clutch cover. - Use a flat blade screwdriver to help pry the clutch out of the housing. Pull straight up. Remove the belt from the motor if its still in place. - Disassemble the clutch with a T10 torx screw driver. Use a small flat blade screw driver to pry the cover for the drive belt off the clutch. Using spring clip pliers remove the clip on the opposite side. Be sure not to loose this. Be careful of the contents of the clutch. There are three ball bearings, bearing retainer, bearing cap, spring and washer that are on the shaft. There's a small silver clip to remove, that will help make it easy to pull the belt and the roller out of the clutch. -Reassemble the clutch by installing the new belt over the roller and pull it through the clutch housing. Make sure the three detents for the ball bearings are facing you. Set the clutch housing on a flat surface and install the three ball bearings, the bearing retainer, the other bearing holder. With the clutch shaft install the washer and spring. insert the shaft through the clutch housing. It will help to have a long socket on the flat surface and you will use it to push down onto while the shaft is going through the clutch housing. This will aid in pushing the shaft up high enough to insert the other sealed bearing and clip. While pushing the clutch housing down on the socket install the bearing then the clip. I used another long socket to push the clip and bearing into place. Then attach the belt for the motor onto the roller and snap it into the clutch housing. Screw the two T10 torx bits back in. -Install the clutch assembly into the housing. There is a ridge that the clutch slides into on the housing make sure this lines up. It should drop in and give it a push to snap it in. Stretch the belt over the motor shaft with a flat blade screw driver. Install the clutch/belt cover. Make note of the long silver pin that the cover slides into. Reinstall the three T15 torx bits. Don't over tighten. - Reinstall the brush housing. Make sure to attach the hose and then snap the cover into the clips on the side. -****THIS IS THE HARDEST PART***** Pull the belt through the assembly. If you have the special belt tool here's where you'll need it. I didn't have one. I used a pair of long needle nose pliers to pull the belt up through the housing and stretched it over the beater bar. It wasn't easy. After the belt was over the beater bar I dropped it into the housing. - Reinstall the sole plate. Job Done. The vacuum works like new. Belt engagement is strong and there's not more clutch noise. We bought our DC33 maybe 12 years ago and this is the first time it needed a belt. Time will tell how long this will last.

Our 20 year old Dyson DC07 animal has been getting a bit of attention lately in an effort to keep it going. It seemed to be working fine, no unusual noises and still collected 'stuff' in the bin, so obviously nothing could be too wrong, right? Web sites say the DC07 has the most powerful motor Dyson ever used, and new machines are very pricey, so we started off our maintenance project with the idea that we would replace items that wear, but are not so expensive that they aren't worth it in a machine this old. We started 2 years ago by replacing the 'permanent" filter under the clear plastic bin, which seemed to improve the vacuuming process. So immediately, of course, the handle on the bin above the purple vortex part developed a crack. No problem - a little 2 part epoxy in the crack, and a double layer of air conditioning adhesive backed aluminum tape brought it back into service, been functioning fine ever since. Studying everything that can be done relatively easily at home, - brush, belts, replacement clutch assembly etc. - showed that many things were not deal-breaking expensive. I assumed that the brush and belt probably took the most beating, so I checked on an OEM Dyson brush, and it was over 3 times the cost of aftermarket! And some people posted that ordered Dyson OEM only got you an aftermarket part like this one, at a higher price. Not expecting too much for $15, I ordered this and installed the part. First off, while you can change the brush without the special tool sold on Amazon, do yourself a favor and buy the tool. Would have made things a lot easier. Removing the old Dyson brush roller, I looked for differences. The most obvious was that this roller has only 3/4's of the brushes as the Dyson unit - 30 brushes per side instead of the Dyson's 40. The New roller test fit in the Dyson without any of the brushes interfering with the bottom plate, so we went to the next step. Dimensionally, the new part seems identical. The Dyson end caps fit on the new unit, and vice versa. The Dyson end caps looked a bit more sturdy, so I used them with the new roller. But internal inspection showed a big difference! The Bearings in the Dyson roller were 625 RS, while the replacement part used 625z bearings. The RS bearings use a rubber contact seal that rests in a special lip in the bearing housing to keep debris out of the ball bearings (even so, after 20 years one of the Dyson bearings had frozen solid, and the shaft was spinning in the bearing instead of with the bearing - hard on motors and electricity bills). The Z model 625 doesn't use a rubber seal, just a metal plate with (sometimes) a rubber ring around the edge to keep out large debris. A "Z" series bearing, per the Bearing Centre, "doesn’t handle heavy loads, high speed or high precision". So I won't be expecting 20 years out of this brush. Checking the length of the brushes the new roller brushes were 2mm longer than the original Dyson roller. Unsurprisingly, 20 years of pounding floors took a toll on the Dyson brushes. We installed the brush using the original Dyson belt. it is probably stretched, but didn't have any obvious cracks or cuts, so we are saving that project for a different day. And, will probably use a Dyson belt at that time as the web has many examples of early aftermarket belt failure. Time for the test! We had vacuumed the house the day before with the DC07 and original brush, looking to see if a new brush made a difference. Yup, re-vacuuming today with the new brush showed that our carpet had more nap and texture than we were used to seeing, and felt a bit more cushion when walking barefoot. And the dust bin had over an inch of fine dirt that hadn't been collected yesterday with the worn brush! Bottom line: You get what you pay for, and there were a number of shortcuts taken to keep the price down - I would have paid $5 more just to have 25% more bristles. BUT, even the budget item works better than the worn factory part . It improved the cleaning at 1/3rd the cost of a factory part, and a 20 year old vacuum should probably be considered nearing the end of life span. On a newer Dyson, I would go with the Dyson parts, but this part does the job for the old purple Animal.

Putting new belts on is a bit tricky. You need to disassemble the clutch housing. Read review January 12, 2023 from Dominic. Video's also on the internet. The new belts seem small out of the package but will stretch into place. A new retainer clip and retainer plier tool is available at Harbor Freight. The T10 and T15 torx long stem screw driver can also be purchased at Harbor Freight. The special belt tool is available from Amazon if needed. I managed to get the new belts stretched into place without the special tool. After replacing the new parts, the vacuum runs like new.

Perfect replacement belts and brush for my DC33. Found a simple video on YT and had my vacuum working again in less than an hour. Very happy to not have to buy a new vacuum.

I have a 23 year old Dyson DC14 Animal - the purple one. We have a dog that sheds like crazy and long blond hair - don't ask me who's hair that is! Anyway, the brush is old, the bearings in the brush re old and it finally gave up the ghost and quit. I bought this belt and brush set and didn't have the correct tools to remove and replace the clutch to replace both belts that are supplied in this repair kit. So I cleaned and refurbished the old belt with automotive v-belt conditioner and put it back together with the new beater brush. This vacuum works like brand new for less than US$12!! I could not be happier!

Brush bar works great - easy to replace. Arrived quickly.

Definitely not as many brushes as the OEM model, but it had a good fit and works well.
