Tornado Tempest Axle Retaining Ring K73430180

The Tornado Tempest axle retaining ring (part# K73430180) holds the brushroll axle (part# K40409820) captive in its bearing on the TV400-W26-U cordless sweeper, with two fitted. Tacony lists it as Retaining ring, Axle.

Retaining a rotating shaft is a job that cannot be done with a clamp. The axle has to spin freely while being held against axial movement, and a ring springing into a machined groove does exactly that — it stops the shaft walking out without touching its freedom to turn. What the ring cannot do is tell you when it has stopped working. It holds by remaining springiness, and a ring that has lost tension sits in its groove looking entirely correct.

Compatible Models for the Axle Retaining Ring

• Tornado Tempest Wide-Area Cordless Carpet Vacuum Sweeper — Model TV400-W26-U

When to replace it

• Any time it has been removed — fit a new one rather than reusing it.
• It does not snap positively into its groove.
• The ring is opened out, distorted or cracked.
• The brushroll axle has developed end float.
• A ring has been found missing during service.

Fitting notes

Remove the battery pack before starting. Use the correct pliers rather than levering with a screwdriver, which stretches the ring permanently. Seat it fully all the way round, then check by trying to move the axle along its length — there should be no end float. Replace both rings together while the assembly is apart.

Frequently Asked Questions

What does the axle retaining ring do on the Tornado Tempest?

It holds the brushroll axle captive in its bearing, stopping the shaft moving along its length while leaving it free to turn.

How do I know if it needs replacing?

If it does not snap positively into its groove, is opened out or distorted, or if the axle has developed end float. As a rule, fit a new ring whenever one has been removed.

What models is this retaining ring (part# K73430180) compatible with?

The Tornado Tempest TV400-W26-U wide-area cordless carpet sweeper. PartSmart lists it against the Tempest alone, and two are fitted per machine.

Why not use a nut or collar instead?

Because the axle has to spin freely while being held against axial movement. A clamp would either lock the shaft or work loose; a ring in a groove does neither.
