How to open power head to remove roller brush to replace the belt

Hello, this is Ava with Think Crucial.

To change the belt of your Shark vacuum, you will need a flat head or a philips screw driver and a pair of scissors or a knife to clean your roller brush.

First, make sure to switch off your vacuum and is unplug from the power. In an upright position (vacuum), remove, empty and clean the dust cup. After cleaning the dust cup, lay down the vacuum horizontally on the floor to access the brush roller unit.

Using the appropriate screewdriver, flathead or philips (which will depend on the model of your vacuum), unscrew that holds the roller cover in place. When you lift the cover of the roller up and if it doesn't lift easily, don't force it because it probably means that you have missed one of the retaining screws. After you removed the cover, you will be able to see the roller assembly and the belt that drives it. If the belt has become worn, lost some teeth, or it has broken completely, you will need to remove the roller itself to be able to replace the belt. Clasp the end of the roller that is farthest from the belt between your fingers and lift it out of its holder. It should lift out very easily. You will then be able to lift out the other side of the roller that is attached to the belt and slip the belt on it. The other end of the belt, if it has not broken completely, will be attached to the motor shaft. That too can now be slipped off the end of the shaft.

With the roller bursh having been removed from the motorised head, I suggest you clean it. You may use a pair of scissors or knife to cut/remove the hair that are stuck. Be careful that you don't cut the bristles of the brush. Also, remove any debris that has found its way inside the roller cover at this point by using a wet towel or tissue.

To replace the belt, slide the new belt around the drive shaft of the vacuum cleaner and onto the seat. Then, replace the belt end of the roller, sliding the belt around the roller inside the plastic guides that are there to stop the belt slipping. Clip the far side of the roller back into the slots provided for it and adjust the belt as necessary to make sure that it is sitting squarely on the roller and the drive shaft and then check that the belt is tensioned properly.

Now, all you need to do is to replace the brush roller cover and tighten it down with the screws that you removed earlier. When you tighten the screws, they should be firmly screwed on, but don't overtighten the screws or you could crack the plastic casing. You can then reconnect the shark vacuum to the power supply and check that everything is working properly.

We have based this guide on the manufacturer's own guidelines, so you should have no problem with your Shark vacuum if you follow these steps.

Hi, it's Allie from Crucial Vacuum!

Changing the belts in your unit is easier than you think. To do so, you will need a phillips head screwdriver. First, start by unplugging your vacuum as a safety measurement. Using the lever in the bottom of your unit, recline your upright until it lays flat. Unscrew all 4 screws from the floor base cover and remove the cover to expose the roller brush and belts of your unit.

Carefully, remove the roller brush by using your hands, make sure to hold on to the side of the roller brush that has the belt so it does not pop out and hit you. Once the roller brush is removed, gently take the belt off the metal spool, and replace with the new belt.

We have a very helpful tutorial in our webpage that can assist you in replacing the belts on your unit:

Turn the power head over so the bottom is facing up. On the bottom towards the back there are two holes (one on each side) where you can get to the access screws. Remove the two screws (you'll need a phillips screwdriver). With the screws removed you can now remove the top cover from the base by pulling out on the two clips on each side of the power head. With the top cover removed you can get to the belt and roller brush. If you need a belt for this model you can get it here:

Remove the bottom cover of the sweeper head, then remove the brush roller along with the belt if still there. Clean the brush end-bearings--the roller ends and the interior of the bushings. Then oil the bearings lightly with 3-1 oil or similar. Place the new belt over the roller and the motor shaft adding any required belt twist (diagram on the casting), then seat the roller and bearings as a unit. Replace the cover and test the roller for running. Hope this helps!

You need a new belt. In order to change it, turn the machine compleatly upside down and place the head on a counter, handle on the floor.
There is a L shaped base plate to remove that has 5 screws in. Once the base plate is off, you see the brush roller and a silver shaft directly back from where the belt would ride. Remove the brush roller, place the new belt, Dirt Devil Style 5 ( see link below ) on to the shaft. Then insert the brush roller, so the belt is on the raised carved out section of the brush roller. Grab the brush roller at each end and stretch it till you are able to put the brush roller back into the base. Turn the brush roller backwards 3 compleat turns and the same forward to seat the belt.
Replace the base plate and you're done.

This machine is made for Sears by Panasonic. The power head, depending on model has a "gear" / cog belt or a standard flat rubber belt. First turn the power head over and see if the brush roller turns easily, if so you do need a new belt. To access the belt you will have to remove the hood from the power head. There are 4 screws, one at each of the corners to take out. Once the hood is off you will see where the belt goes and find "teeth" in the motor shaft for the motor / brush roller if you need a gear belt. If both of these are flat you need a rubber belt.
You can go to sears.com and find the belt you need with the vacuums model number.

That means that you need to replace the belt. Here is the belt you need for your model.

Hoover Windtunnel Canister Belt

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.
Another item to check is if your dust filter is not plugged up which is located behind the removable dirt cup. This is the cup that you remove that collects the dust/dirt/hair from your floor. Take the removable dirt cup out by depressing the gold button and then look behind where the dirt cup sits for filter. This can be cleaned out by washing it with soap and water in the sink but make sure you let it dry overnight before placing it back in the machine. This probably causes some of the overheating when not enough clean air is passing through the machine.
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.
