How do I replace the drive belt on a kirby G4? Actually the belt is already replaced I just need to know how to reattach that front part back onto the main vacuum. HELP

Remove the head from the machine, and unlatch and remove the bottom plate. The brushroll can now be pulled or pryed out. Slide the new belt onto the brushroll and center it. When re-installing the brush, note that one end cap is wider than the other. The brush caps are also marked with 1, 2, or 3 notches to adjust for wear. In normal use, setting 1 should face the carpet. Be SURE both ends are on the same setting. Replace the metal rug plate and turn the belt lifter counterclockwise to stretch the belt into a loop. Place the head back on the machine, latch it firmly in place, and turn the belt lifter clckwise to drop the belt onto the motor shaft.

Replace the belt it is probably worn. You can get a replacement here:

Kirby G4 Belt

your belt has probably been stretched to the point where it will not work so good.

1)First, you turn the square belt lifter on the front of the power nozzle until the red arrows line up (belt off of the Kirby's driveshaft but on the "hook" inside the power nozzle) 2)Remove the power head from the front of the machine. Now that it is off the Kirby, you can turn the square belt lifter until the green arrows line up. (Belt on, which means on the driveshaft on the front of the Kirby when the power nozzle is on the Kirby which makes the brushes spin. Now that the power nozzle is off of the Kirby, the belt isn't actually resting on anything but the green arrows will still point to belt ON ) This removes the belt from the "hook" so that it can be slipped off the brush roll. 3)Turn the power nozzle upside down and release the two clips that hold the metal baseplate on and remove the baseplate. 4)Grab the brushroll and pull it out of the power head. Slide the new belt onto the center of the brushroll. It will hang loose...it doesn't have to stretch around anything yet. MAKE SURE THAT THE BRUSHROLL SPINS FREELY!! If it doesn't, you'll burn all new belts quickly due to the added strain on the belt. 5)Look at the ends of the brushroll. The brushroll has three height settings..you should see notches AND NUMBERS on the sides of the brushroll's end caps. ONE notch (also #1) FACE UP on BOTH sides is the first setting and should be used when the roller is new. Three notches is the last setting used before a new roller is needed and should be used if the brushes are short and worn. Put the brushroll back in, making ABSOLUTELY SURE sure that the SAME NUMBER of notches and the same raised number on the edge are FACE UP on BOTH sides. This is important, as the brushroller will be unbalanced if inserted wrong. Also, one end cap of the brushroll is larger than the other and will only fit onto the larger notch in the power nozzle. 6)Replace the baseplate by fitting the front clips into place and then push it down in back and secure it with the two rear swivel clips. Make sure it fits securely down over the bumper on all sides with no suction leakage. 7)Turn the belt lifter to where the RED arrows line up, making sure that the inner "hook" grabs the belt and stretches it up while you are turning it. Once you have the belt stretched up, put the power nozzle back onto the Kirby and lock it in place. 8)NOW...turn the belt lifter back to GREEN. If the little green light on the power nozzle lights up when you turn it on, CONGRATULATIONS!!! The brushroll is spinning!!

Hope this was helpful :) and thank you for using Fixya!!!

It is similar to the G4 but without the tech drive so is easier.

I can help you but, I'll need to ask a few more troubleshooting ?'s

Facing vacuum,turn belt lifter knob counterclockwise till it stops.Lift headlight hood,and unlatch brushead,and remove.Looking thru the hole in back,turn belt lifter knob clockwise to release belt.Remove bottom plate,and bend one end of bracket to remove end of brush roll.Slip new belt on and replace brushroll back into bracket,and replace bottom rug plate.Looking thru hole in back,turn belt lifter knob until the hook inside picks up belt.Replace brushead,and again,turn belt lifter knob clockwise to drop belt onto shaft.

Lift the light bulb housing up and you will find a latch that will rotate to release the front agitator housing and remove it from the machine. On the bottom of that housing, there are two latches that secure the bottom plate that covers the roller. Remove the plate and the roller will come out. Be sure to notice that the roller has a magnet at one end that lines up with the indicator that shows you when the roller is turning - it's the little green light that glows while you are vacuuming. The roller needs to go back in the same way it came out. O.K. Take your new belt and position it around the middle of the roller and drop the roller back into place and replace the bottom plate. On the front of the housing, there is a big square "knob" and you can rotate that piece. If you look inside the hole on the other side of the agitator housing, you will see that there is an arm that moves with the square knob. The end of this arm will catch the belt and with a little effort, the knob will rotate and lift the belt into position for replacing the housing back on to the machine. once you have the housing back on the machine and secure, you rotate the square knob back around and the belt will sit down on the drive shaft. If you look at the top of the agitator housing just above where the knob is, you will see a red and a green arrow which indicate which way the knob turns to do the "remove" belt or "replace" belt. I hope this helps. Once you do it properly, it actually is quite easy.

first things first...take the powerhead off of the front of the kirby. If you look at where the powerhead connects to the front of the kirby and you'll see a large hook...turn the hook using the crank on the front of the powerhead so that the belt is pulled up and away from the brushes. (OFF position) The hook stretches the belt so that it can fit over the fan driveshaft (its the finger looking thing that sticks out of the front of the kirby when the powerhead is removed.)

Next, place the two "feet" of the powerhead onto the "perch" located on the front of the kirby (under the driveshaft opening)....lock it on by turning the silver lever on the top of the kirby (the one under the hood/light)


Now spin the knob on the front of the kirby from off to on. This releases the belt from that hook in the powerhead so it can rest on the driveshaft. Off means the belt is off of the drive shaft and the brushes won't spin. On means the belt is on the driveshaft and the brushes will be spinning. But remember, the belt has to be stretched open on that hook inside the power head BEFORE the powerhead is placed on the front of the kirby. Otherwise the belt won't be connected to the spinning driveshaft, and the brushes won't spin
