Tornado Tempest Spring 4 x 4 x 16 K73180070

The Tornado Tempest spring 4 x 4 x 16 (part# K73180070) is one of two springs on the brushroll assembly of the TV400-W26-U cordless sweeper. Tacony’s own record gives its dimensions as SPRING 4X 4X 16, which is what separates it from the other brushroll spring (part# K73180840) — both are catalogued under the single word Spring.

Springs are the parts most often substituted by eye during a field repair, and the Tempest carries seven of them across its assemblies. Fitting one of the wrong rate does not produce an obvious failure; it produces a mechanism that works but not quite right, which is the hardest kind of fault to trace back afterwards. Where a published dimension exists, as it does here, it is worth ordering to.

Compatible Models for the Spring 4 x 4 x 16

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

When to replace it

• Coils have taken a permanent set and no longer stand apart.
• Corrosion has pitted the wire.
• The brushroll assembly has been dismantled.

Fitting notes

Remove the battery pack before starting. Note how the spring is located before removing it. Do not substitute the other brushroll spring (part# K73180840) — the two have different dimensions and rates, and the mechanism will work while behaving subtly wrongly. Check the mechanism returns under its own power after fitting.
