Easy to fix. The burning rubber smell is hair in the roller against the belt! Congrats, you have a healthy vacuum, you are lucky! Unplug the vacuum, remove the screws that cover the belt and roller brush. If you are nervous, take pictures with a cell phone or digital camera as you go for re-assembly. ok, pull the long roller out of it's slot and out of the vacuum. cut all hair off the roller and carefully move the belt from side to side to do the same. If the belt slips off, it slips back on easily. If the area is too tight for fingers guide it back on with any long thin wooden object. You can squeeze the belt to narrow it and slide it back over the thin metal rod that spins it from the motor. Slide the roller through the belt and back into it's slots. If it won't slide back on, turn it a quarter turn. Repeat till it does slide back into place. Put the face plate back on-tighten screws, flip it over, plug itr in and it should work!
The pedal assembly must be replaced,( part # 558401S), as it has a gear pressed to it which has come loose. The handle, switch plate, and upper motor cover must be removed first. To remove the plastic switch plate, remove it's screws and insert a flat screwdriver into the rectangular slot in it to pop it of. Four screws hold the motor cover in place. Next the switch button must be removed. The Techdrive assembly can be removed by removing the three screws on the bottom. Drop the drive down, and unhook it's belt from the gear on the end of the armature shaft. The pedal assembly can be removed by removing the remaining screw from the bottom of the drive unit. The N/D pedal has two parts - the pedal itself, and the shift cam. Observe carefully how these units fit together. After installing the new pedal and replacing the screw and washer to secure it, re-install the drive unit. The shift must be in the Drive position to install it, and replace the belt. Be sure to line up the arm on the drive unit so that it engages the slot at the base of the handle pivot and re-install the other items
It sounds like you didn't clean the bearings. On one end of each brush is a bearing, probably in a yellow housing. Pull the bearing off the axle, and you'll find it's full of hair underneath.
Obviously, the brushes should turn freely and slot back in the housing easily. If they don't, you have to look really carefully to see what's stopping it. I've given you the most likely issue based on my experience (!) but if that fails you'll have to look at the physical fitting of them carefully to see where extra bulk (dust/hair/whatever) is preventing the easy fit.
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.
FIrst, remove the dust bin part and the brushes. Then, there are four
screws on the bottom gray panel which have to be removed first in order
to get to the gears which hold the brushes. I did not remove the little
sweeper brush on the front, but I just slide it through the hole in the
gray panel.
Then in order to get out the orange section which actually holds the
brushes, there are four screws which must be removed. The orange
section is attached to a blue section. This entire unit comes out by
sliding it toward the area where the dust bin goes, being careful not
to tear the light gray rubber gasket which covers the side.
Once that section is removed, there are two screws on each side. These
screws hold the orange thing to the blue thing. Once the screws are
removed, lift up only the side which has the white squares into which
the brushes are inserted. These are actually the back side of little
gears. There is a face plate on the outside of the orange part on this
end. The other end contains a bunch of wires and I was careful not to
disconnect any of them.
The face plate has six screws which must all be removed. Use caution
when removing the face plate. Hold it up so that all of the stuff
doesn't fall out. It has a bunch of gears, little brass looking
fittings and grease. Take care to only remove the gears which have the
squares which hold the brushes AND do it one at a time
unless you like working jigsaw puzzles. I used tweezers and a pin to
clean the "gunk" consisting of hair, fuzz, etc., out of the little gears
There is a black gasket type thing that fits on the bottom of the cyclone part that is supposed to keep dirt and hair from getting down to that filter. Yours is probably missing - mine was. I called Dyson and they sent me a new cyclone for free.
I have had problems with the belts on my Mach 5 overheating (smell of burning rubber) and also with the motor overheating and shutting down.
I learned the hard way that one of the issues might be that the roller/brush on the bottom of the unit has a metal bearing inside the roller/brush that can become clogged with hair (both human and pet hair) which effects performance of the unit. It’s fairly easy to fix.
Lay the vacuum on the floor so that you can see the roller/brush. Then remove the phillip head screws that hold the protective plastic plate over the roller/brush. (There are about 6 screws that hold this plastic protective plate in place) Also, you will be removing the (1) screw that also holds the plastic plate over the belts. There are (2) belts that you can remove and when in doubt replace these (2) belts for around $9.00.
Once you have the protective plastic plate off that covers the roller/brush disconnect the belt is around the roller. Take the roller and cut off any hair that is wrapped around the roller. Next, grab the roller by each end and twist the ends caps and (1) of the ends will unscrew. Once you have unscrewed one of the ends remove any hair or dust that is trapped under this cap. (Be careful not to lose the small metal washer that sit on top of the bearing)You will notice under this cap is a metal bearing that can become clogged and jammed with hair. The hair should come out fairly easy and allow the brush to spin fairly easy once you have screwed the end caps back in place test that it spins freely. If it doesn’t spin freely replace the roller/brush with a new one for about $23.00.
When you put the belts back on the thick rubber one (Belt # 40201-271) has probably become stretched and should be replaced for about $3.00. The small diameter belt that goes over the roller/brush probably does not usually need to be replaced and does not usually fit very tight. I have heard that people will take the small roller/brush belt and turn it upside down to get a better fit.
I just did this on my Mach 5 and it runs like a new machine. I did end up replacing the roller/brush head.
Hopefully you will find this useful.
Remove the Yellow connectors on the end of the brushes and clean around the pin well. If there is too much there, the roomba thinks there is something stuck and goes into clear mode (as if there is a chord stuck).
THESE BRUSHROLLS HAVE A RUBBER PAD WHICH IS CALLED A CLUTCH PAD. THIS MAY BE WORN, OR THE SLIDERS MAY JUST NEED A SMALL WASHER WHICH YOU CAN GET FROM YOUR LOCAL RICCAR DEALER. ALWAYS MAKE SURE YOUR LINKAGE ROD IS CONNECTED PROPERLY. ROD SHOULD BE ON THE BOTTOM PLATE SIDE, IF YOU HAVE THE MACHINE TURNED OVER WITH THE BOTTOM PLATE OFF IT SHOULD BE ON TOP OF THE BRUSHROLL.
