Kirby G3 - jump - skip problem

I can't figure out why my vacuumm does and jumpy - skip several times when I push it forward. It is very irritating. I've tried different level settings, etc. but nothing seems to work. Has anyone else had this problem? What can I do differently?

    I have the same problem, no help from a dealer at all. We tried changing the brush, raising the level of the sweeper, no help. It's frustrating. One repair person called it "chatter". I'm about to by a Dyson.

    i have had the same problem 2x. the first time i had it fixed at a mom and pop vac store and he rigged it with a replacement piece from a gen4. it worked for quite a few years, then back to the same old thing. my local kirby man fixed it 15 minutes with the right piece. he diagnosed the problem as a transmission problem, a problem with the drive/neutral mechanism. $23 i was out the door. he even let me watch him, so if it happens again, i can adjust it myself with just a screwdriver. just tell you kirby guy it is a transmission issue, and in my case, fixed with a thin metal screw in piece.

    My Kirby no longer moves forward or backward. It seems that it is stuck in neutral. Any ideas how I can disassemble and check the 'transmission'? I am suspecting a failed switch.

Skipping or no drive to Kirby G3. My G3 stopped driving forword/backwords the other day. So I decided to strip the drive unit down in the gearbox there is a drive belt which has snapped so requires replacing which I will do, As for jumping it could possibly be there are some teeth missing on the same drive belt. It's worth having a look.
This is not for the faint hearted as there are a lot of bits to remove.
1 Remove all attachements (Bag,Brush assm & Handle).
2 Remove crosshead screw above nuteral/drive switch at rear gently insert a flat blade screwdriver in the slot above the on/off switch and push in while lifting the plastic cover at the rear where you have just removed the screw.
3 Remove top cover, 4 Screws hold this on,2 under the front light cover at the top and 2 at the rear where you have just taken the plastic cover off.
Check dive belt from center of the main drive motor to the g/box ( If any damage or wear replace.If teeth missing this could be the reason for jumping and you may not need to go any further).
4 With a flatblade screwdriver gently prise off the on/off switch and leave it to dangle.
Now we need to get the Gearbox out.
Turn the machine over.
1 Remove the three T20 screws NOT THE Crosshead.
2 Remove G/Box ( It's a bit tight but it will come out ).
Looking from the rear.
3 In the center of the g/box there is the clutch assembly,remove the 'c' clip at the side of the clutch and reomve the crosshead screw ( Take care not to lose the washer).
4 Remove the crosshead screw from the base of the unit (see item 1) pull the drive/nuteral switch out.
5 Remove the 2 Torx screws holding the wheel assembly and remove assembly.
6 Turn unit over and remove the torx screw from the unit.
7 Turn the g/box over and Gently open the g/box taking care not to lose anything.
You should see 3 wheels 1 at the top and 2 at the bottom, the 2 at the bottom should have a belt joining them together ( on mine it was wrapped around just one of the gears).
8 Replace the belt and reassemble in reverse order.

Hope this helps I will try and get a video done and put it on u tube.

Hopping - jumping - skipping - bouncing

It could be that you have the brush settings wrong for your carpet type. Check if the brushes are on number 3, if so, try dropping them down a notch or two and see if that does it. I think that the brushes when spinning spin towards you, so when pulling the vacuum back, the brushes are helping to drive, when pushing forward, you are pushing against the brushes. If the brushes are sticking out too far, it could cause bouncing/jumping. HTH :)
