Part number 141690S is the genuine Kirby floor nozzle housing assembly for the Generation 3 upright, supplied without the brush roll and without the belt. It is the outer nozzle housing that carries the bumper and the belt lifter and mates to the front of the machine. Vacuum repair shops and Kirby owners buy this part when the original housing has cracked, when the belt lifter mechanism has failed, or when a drop has broken a mounting point while the rest of the nozzle internals are still serviceable.
Built for
- Vacuum repair shops rebuilding Generation 3 machines for customers
- G3 owners whose belt lifter no longer engages or releases
- Anyone repairing impact damage to the nozzle housing or bumper
- Cleaning contractors maintaining older Kirby uprights in a fleet
The belt lifter matters more than it looks
On a Generation 3, the belt lifter is the mechanism that takes tension off the belt when the machine is switched between floor modes and when the handle is upright. When it fails, the symptom is usually a belt that burns through quickly or a brush roll that will not disengage, and owners often replace belt after belt before tracing it to the lifter. Because the lifter comes already fitted to this housing, replacing the nozzle for a cracked shell also resolves a worn lifter in the same repair.
What is and is not in the box
This is deliberately a housing-level part. The brush roll, the drive belt and the bottom plate are all sold separately, which is what the less brush roll description refers to. If your brush roll is worn or your belt is stretched, order those alongside this housing rather than assuming they are included. Reusing a worn brush roll in a new housing is the most common reason a repair does not restore pickup.

Frequently asked questions
Does 141690S include the brush roll, belt or bottom plate?
No. Kirby supplies this as the nozzle housing with bumper and belt lifter only. The brush roll, belt and bottom plate are separate parts.
Is the belt lifter already fitted?
Yes. The belt lifter and the bumper come attached to the housing, so a failed lifter is corrected by fitting this assembly.
Which machines does it fit?
Kirby lists 141690S for the Generation 3 and G3D uprights. Kirby nozzles are generation-specific and do not interchange with the G4 or later machines.
Why is my belt burning through repeatedly?
A worn belt lifter is a common cause, because it leaves tension on the belt when the brush roll should be disengaged. Since the lifter is part of this housing, replacing the nozzle addresses it.
Should I replace the brush roll at the same time?
Check the bristle length first. If the bristles no longer stand proud enough to reach carpet pile, a new housing will not restore pickup on its own.
