A Kirby that still rolls freely but no longer pulls itself forward is almost always a driveline problem, not a motor problem. The rear axle carries the gear that transmits the machine's powered drive to the rear wheels, and that gear is the part designed to give way first. This is the rear axle assembly with overload gear for Kirby Generation series upright vacuums.
The overload gear is a deliberate weak point. When the drive binds, the gear sacrifices itself so the transmission and motor components that cost far more survive. That design choice is good engineering and it is also why this is one of the most commonly replaced parts on a Generation machine. Technicians and owners who service their own vacuums keep this repair in the routine rebuild list.
Built for
- Restoring self-propelled drive on a Generation series Kirby that has lost it
- Routine rebuild work on used machines being returned to service
- Repair shops stocking common Kirby driveline wear parts
- Owners doing their own maintenance rather than replacing a working machine
Fit
Parts sources agree that this axle assembly covers Kirby Generation series machines from the G3 forward, but they do not agree on how far up the range it extends. Some list it for the G3 and G4 only; others show it carrying through later Generation models. Before ordering, match the number stamped on your existing axle or compare against the parts diagram for your specific model and serial. If the number on your machine differs, contact us and we will check the current supersession rather than guess.

Frequently asked questions
My Kirby rolls but will not drive itself. Is this the part?
That is the classic overload gear symptom, and this assembly is the usual fix. Before ordering, rule out the drive belt and the transmission engagement lever, since both can produce the same complaint.
What does the overload gear actually do?
It is a sacrificial component. Under an abnormal load it fails on purpose so that the more expensive drive parts behind it are protected. Replacing it is a normal service item, not a sign the machine is worn out.
Which Kirby models does it fit?
Sources agree on the Generation series from the G3 forward but disagree on the upper end of the range. Match the part number on your existing axle, or send us your model and serial and we will confirm before you order.
The part number 555211A comes up when I search. Is that the same thing?
Parts sources report 555211A as the supersession for 102095G. Supersessions are common on a platform this long-lived. If you are unsure which number your machine needs, contact us with the model and serial.
Do I need special tools to install it?
It is a hand-tool job for anyone comfortable working inside a Kirby nozzle and drive housing. If you have never had the machine apart, a repair shop can usually turn it around quickly.
