Tornado Tempest Side Broom Knob K63213430

The Tornado Tempest side broom knob (part# K63213430) is the star grip that locks the side brush height setting on the TV400-W26-U cordless sweeper. Tacony lists it as Knob, Side Broom and the parts book as a star grip. It clamps the height adjustment bracket (part# K50963980).

A star grip is chosen for a setting that operators change without tools. Its lobes give enough leverage to clamp properly by hand, which matters because the joint it holds is resisting a brush being dragged sideways across carpet. As the lobes wear or crack, the achievable clamping force drops, and the height setting starts to creep — usually blamed on the bracket rather than on the knob doing the clamping.

Compatible Models for the Side Broom Knob

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

Symptoms that point to the knob

• The height setting will not stay put even when the knob feels tight.
• Lobes are cracked, worn round or broken off.
• The knob spins on its thread without clamping.
• It has to be tightened with pliers to hold.
• The thread is stripped or cross-threaded.

If a knob needs pliers to hold the setting, replace it rather than continuing — pliers on a plastic grip finish the lobes off quickly and the next stage is a knob that cannot be undone at all.

Fitting notes

Remove the battery pack before starting. The knob clamps the height adjustment bracket (part# K50963980) with its washer (part# K51150420). Check the thread it runs on for damage while the knob is off. Set the brush height, tighten by hand only, and confirm the setting holds after a few minutes of running before returning the machine to service.

Frequently Asked Questions

What does the side broom knob do on the Tornado Tempest?

It is the star grip that clamps the side brush height adjustment, letting an operator set and lock brush height without tools.

How do I know if my side broom knob needs replacing?

If the height setting creeps even when the knob feels tight, if the lobes are cracked or worn round, if it spins without clamping, or if it needs pliers to hold.

What models is the side broom knob (part# K63213430) compatible with?

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

Can I just tighten it with pliers?

Not as a long-term fix. Pliers on a plastic star grip destroy the lobes quickly, and the next stage is a knob that cannot be undone at all. If it needs pliers to hold, replace it.
