Tornado Tempest Side Broom Locking Ring K73430830

The Tornado Tempest side broom locking ring (part# K73430830) retains the side broom pivot bolt (part# K53181070) in its height adjustment bracket on the TV400-W26-U cordless sweeper.

A locking ring holds by springing into a machined groove, which means it retains without clamping. That distinction is the whole reason it is used here: the M12 pivot bolt has to be held captive while the height adjustment still moves on it. A nut would either clamp the pivot solid or work loose; the ring does neither. What it will do, eventually, is lose tension — and a ring sitting in its groove without gripping looks exactly like one that is working.

Compatible Models for the Side Broom Locking 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 pivot bolt has developed end float.
• A ring has been found missing during service.

The first point is the one that matters. These are designed to be renewed, they cost very little, and the failure mode — a pivot bolt walking out of an assembly carrying a spinning brush — gives no warning.

Fitting notes

Remove the battery pack before starting. Use the correct pliers rather than levering with a screwdriver, which stretches the ring. Seat it fully in its groove and check by trying to move the pivot bolt axially — there should be no end float. Confirm the height adjustment still moves through its full range afterwards.

Frequently Asked Questions

What does the locking ring do on the Tornado Tempest?

It retains the side broom pivot bolt in its groove without clamping it, so the bolt is held captive while the height adjustment can still move on it.

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 pivot bolt has developed end float. As a rule, fit a new ring any time one has been removed.

What models is this locking ring (part# K73430830) compatible with?

The Tornado Tempest TV400-W26-U wide-area cordless carpet sweeper. PartSmart lists it against the Tempest alone.

Why not use a nut instead?

A nut would either clamp the pivot solid — stopping the height adjustment moving — or work loose under vibration. The ring retains without clamping, which is exactly what this joint needs.
