>> ALEC: Hi there, Smart Alec from VacuumSpot here. Today I'm going to show you how to access
the brush roller, the brush bearings and the clutch in a Dyson DC07 and DC14 vacuum cleaner.
First step is to tip your machine upside down, so that you can see the base plate. I'll just
wait for my camera man to come in. There are three lugs here that you need to turn ninety
degrees.
Then this just comes away. Now, this is going to fix a couple of fairly common problems.
One is that the brush roller gets jammed, and it creates a very loud ratchet-ey noise.
The other one is that you get material caught in the bearings at the end of your brush,
which can also slow your brush down, wear out the clutch or create that same ratchet
noise. Now, I'm going to use a brush removal tool,
but if you don't have one of these, it is possible to do this with a screwdriver, it's
just much much harder. So, you lever the belt up and over our bridge
here,
and that allows the brush to come out fairly easily.
Then from here, we can have a look, the ends just twist off like so,
and you can have a look for any material in the end here, and here.
You're best to actually pop this drive shaft back in, and tap, until the bearing itself
actually comes out, and just check if it rolls nice and smoothly.
There is one on the other end as well. Take that out, and there it is.
Now, if your bearings are slow or a little bit rough, you are going to need to replace
these, they are a size six two five. [625] Fairly commonly available from most bearing
supplies place, or, of course, online retailers.
Pop those two back in,
and they go on and just sit to one side. When you hold the ends, it should be able to turn
fairly easily like that. Now you take off the belt from the bridge.
What you have to do now is hold the front, while you gently lever the back. You can see
what I'm doing here, I'm holding the front, and levering
up the back. The same over here, hold the front, lever
up the back. That allows this cover plate to lift out of the way. This gives you access
to the clutch now. If I wanted to change this clutch out, the
next step is to put a small flat blade screwdriver just behind this part here
of your clutch assembly. Push that in and lever it out, then while you hold that, turn
the machine around and do the same part here. That will lift off.
Now, the clutch has got three screws. One here, one here and one which is hidden by
our U bend. So lift that up and it is down there. You will need a number 15 Torques driver
to get at these.
I'll just quickly undo these to show you.
The plate comes off, and now you can see the clutch to the drive shaft belt goes from there
to here. You need to unhook that, and then use it to lift up the clutch assembly.
Now, one of the most common causes of a worn out clutch will be seen here. This white pulley
often ends up with melted belt on it, it will turn black and it won't run freely.
If this is at all stiff, or not rolling, it needs to be replaced completely. If this belt
is much longer, this belt can be replaced on it's own.
It's fairly easy to put this back into place. You just line up your two holes here and here
with your locator's there and there.
Then it will click into place. Pull your belt up and just test if it runs freely. Again
here, if that runs freely and this belt is in position, the clutch is installed properly.
You will need to note that this arm here lines up with the body here, that is what actually
engages the belt when you lower the handle down.
Now, I'm going to quickly put this back together, but take your time when you are doing it,
particularly your first time, so that you don't make mistakes, and need to pull the
job apart again.
I dropped a screw down there.
Just going to grab that back.
OK, so all three screws are in now. Now is the time to put your dress cap on. Just line
up the cut-out with the arm, and that just presses on.
At this point, your internal hose goes onto this shoot here, the one closest to the clutch,
and that just
presses on as well. Now, when this goes back on, you just position
it in the gap on both sides, and as you pull, you are pulling it back toward the body of
the machine. Try and do both sides simultaneously, so that
is a smooth and even fit. Now we need to get out the brush removal tool, and put your belt
on that side first, and then this side second.
You line up the smooth section under here, remembering that the brush has small locator
points here, and they are on the part closest to you.
Push them down and now you can lift the belt off, and back down. This is another chance
just to roll the brush and test if it runs freely.
Now you put your base plate back on.
Do up the screws. Don't forget to put your U shaped bend back on, otherwise you won't
any suction in the up-right position.
That latches on.
There you have it. A clutch removed and a brush roller checked,
on a DC14, but it also works on a DC07. Another tip from Smart Alec at VacuumSpot.
