How to service a G series Kirby
First you will need to make a list of parts that you will need to get. Definitely get a new belt (dont use an old one that has been laying around for years they crack, split, and fail quickly) take the brush roll nozzle off and inspect the fan for chips, and cracks around the center. Replace if necessary. Next remove the brush roll, it must spin freely replace if it feels tight or makes noise. Now as long as the vacuum worked before, those three things are what you could need (plus any broken parts). Now that we have the parts we can get started. remove the bag, handle, scuff plate and cord. there is a release button for the handle. The plastic mini emptor on the bottom of the bag rotates away from the body and lifts off. And the scuff plate pops off using a flat head screw driver in the center slot and prying up. You will see 2 screws under the scuff plate and two screws in front on the top, remove those 4 screws and lift top cover off. you will now see the inner workings of the motor.
If you need to replace your fan take out the other screws in the front, there is two under the top cover, two towards the bottom, and one more near the center. hit the bottom of the aluminum cover with a rubber mallet til it pops off. there is a spot near the back of the motor where you can insert a wrench to hold the motor shaft. use a pick to twist off the front spindle (left hand threads opposite from normal) remove and replace fan. use a small bead of liquid gasket to seal the compartment and install screws. (it helps to have a piece of 2 x 4 to set the machine on and install the front cover.
Now we will move to the motor compartment. First, vacuum out as much of the fuzz and dust out of the inside as possible being careful not to disconnect any of your wires. You can also blow it out make sure to blow through the motor to get all the carbon dust out. The cleaner you get everything inside the better. Next inspect your motor carbon brushes and commutator for wear. If that is good spin the front shaft, listen for bearing noise and feel for stiffness. If the bearings feel bad then you should rebuild. inspect the transmission gear, motor gear, and belt for wear. replace if necessary. (kirby recommends that you replace all pieces at once because if you only replace one, the worn parts will damage the motor and transmission internal parts) Now apply some 3 in 1 oil to the top slide where the handle connects. Do Not Disassemble! there are way bearings in the assembly and if its not assembled right the self propelled system will not work properly. Move the assembly back and forth to ensure that all of the way bearings receive oil. Now you can reinstall the top cover, cord, scuff plate, and the bag. The brush roll nozzle, clean all hair and twine off brush roll if you are using the same one. Slide a new belt over the brush roll. make sure to clean and wipe out the nozzle. The brush roll can only be installed one way, one of the end caps are bigger. They should always be numbered with 1 to 3 new brush roll gets set on one and you can rotate higher numbers for more wear. install brush roll rotate belt hook and install nozzle. Plug it in and take it for a test drive. You have now successfully serviced your Kirby Generation series vacuum. Kirby recommends this be done once a year.
