Replacing belt for bar - Westinghouse WST1551 Wired Deluxe Upright Vacuum

Do you mean the beater bar belt or the motor shaft belt? If so, you need to set the vacuum in a horizontal configuration and turn the vacuum upside down. Next remove the five screws from the base plate and lift the base plate off.

To replace the motor shaft belt, remove it from the outer pulley and the motor shaft. Put the new belt on the motor shaft and the outer pulley. To replace the beater bar belt, release the motor shaft belt to allow access the beater bar. Lift up the beater bar assembly to remove the beater bar belt. Replace the beater bar belt. Replace the beater bar assembly. Replace the motor shaft belt. Turn the beater bar assembly by hand to check that the unit is seated correctly. Put the base plate back on the vacuum. Align the tabs on the base plate with the slots on the vacuum and replace the five screws.

I hope this helps.

hmmm some of the vacs i see having a brush bar are powered by the vac motor via a belt system or by means of a extra brush bar motor and belt make sure both are replaced (mind ya mostly its just the belt thats broken and need replacement)

1. Get a long screw driver (probably phillips head) a strip of tape.
2. Look around underneath your vac for screws... look carefully because sometimes they are sneaky and hidden in weird areas like under the wheels, etc.
3. Take screws out stick them in order on tape turned upwards. (remember how you took them out.)
4. Gently remove the bottom cover.
5. Clean and remove debris, hair, dust bunnies, rocks... whatever.
6. Determine where the belt goes, disengage the beater bar on that side (may need to unscrew something) Belt on beater bar gears. Other end of belt on motor end... then stretch belt with beater bar until it fits back in it's place and replace any screws, etc.
7. Make sure the belt is seated properly.
8. replace cover, screws... test.**

** sometimes belts require that you put a twist in them so it can transition from the motor's direction to the beater bar's direction... if you twist the wrong way... the beater bar will spit dirt out the front of the vac.. (it's bulldozing it) In that case remove cover and twist the belt the other way.

Good luck.

Hello, W/D here.
Since the brush will not spin, but the motor works, either the belt has come off of the motor shaft, the belt is worn past it's useful life, or the beater bar has seized.
1. Turn off the power (unplug).
2. Remove the bottom plate. With the plate off, use your finger to test the tension of the belt. It should be tight, and roll when you roll the beater bar by hand.
3. Remove the beater bar and belt. Inspect the beater bar, particularly by the bearings. Remove any twine, hair, etc.
4. Inspect the belt for abnormal wear. If there is any significant wear in the belt, replace it.
5. Reassembly is in the reverse order. Place the belt on the beater bar. While holding the beater bar close to it's position, place the belt on the motor shaft. Rotate the beater bar bearings to their proper position and install the beater bar. Replace the cover plate.

Best regards, --W/D--

The belt is supposed to be tight, but the beater bar bearings are probably full of string, hair, and thread. Remove the bar, remove, clean, and oil the bearings (3-1 or similar). Leave the belt off for a moment, and install just the bar. Spin it with your fingers--it should revolve freely--if not, redo the clean/lube process again making sure to clean the inside of the bearings with a Q-tip swab. Once the bar spins freely, remove it to slide on the belt and reinstall. Hope this helps!

The belt doesn't have to be broken to make the vacuum not work correctly. If the belt is stretched the vacuum won't operate the way it is supposed to. You can get replacement Dyson Belts here:

It's a fairly simple job. The belt just loops over the end of the beater bar and motor shaft. Need to take the cover off the beater bar housing to get to it. Most difficult part is stretching the belt while putting the beater bar back in the housing.

Hi,

Place the belt on the motor shaft then slide the beater bar into the belt. Center the belt where it should be on the bar, then insert the bar into the end sockets. It'll be tight. Replace the base blate. Done!

idk lol

Provided that the motor isn't loose, the belt should fit tightly. If you had reassembled the beater bar back in the vacuum improperly, the belt would be tighter, rather than looser. If you are sure that the motor isn't loose and the beater bar was reinstalled correctly, then either tha belt slipped back off the motor shaft, or they sold you the wrong replacement belt.
