Put new belt on and the wheels are to high in the front of sweeper

belts will stretch when they slip. There no adjustments on beater-bars. The way to prevent this is to have a height adjustment to be high on high pile and low for low pile rugs.

If it has a belt it goes around the sweeper part and connects to the motor.

there is a video at the bottom on changing belts on a Kirby

get a fillipshead screwdriver, put the vacuum facing you so the brush is infront of you, you will see 4 screws on each corner.unscrew those and when you do there will be a space where you will see a shaft that points out. take the old belt off and put one part of the new belt on the shaft and the other part on the brush near the belt. (there will be a little brown part on the brush for the belt to lay on) make sure its secure and screw the screws back and your ready to go !

Sounds like the belt is maybe slipping did it brake the new belt as well?

Hi there!

If you are talking about the main sweeper attatchment, Lift the light at the front of the upright machine, Make sure the belt inside the sweeper it is over the hook when you turn the handle on the front anti-clockwise to "belt off". Turning handle raises belt.
The hooks at the bottom of sweeper go over the bar at the base of the body. It helps to lift the wheels slightly.
When hooked on, rotate handle clockwise to "belt on" and close the light cover.

Is this solves the problem , please take a moment to rate as Fixya! If you need more help, just ask again on this question.
Thank you.

Maybe it's stretched and is slipping causing friction and heat.
Try a new belt.

the above link shows you how to change the belt on the g-series kirbys but it will apply to the heritage edition as well...the only difference is the color...some of the arrows may be missing on the front belt lifter knob...but they are little differences...

hope this helps!!!

on the bottom there should be a few screws take them out and a cover should come off the belt is right there. hope this helps

On the Front of sweeper is a Tab Turn it and it will release the Beater Bar assembely Put the Belt around the Bar and put the Belt on the inner tab Turn and the Belt should go around motor Good luck ttech
