Tornado Tempest Screw M5 x 10 K73060710

The Tornado Tempest screw M5 x 10 (part# K73060710) secures the brushroll belt pulley (part# K56250390) on the TV400-W26-U cordless sweeper. Tacony lists it as Screw M5x10, Tempest. It is used on both the brushroll and filter and blower assemblies.

At 10mm this is the shortest M5 on the machine, and the length is chosen for a reason: it clamps the pulley without reaching into the shaft bore behind it. A longer M5 threaded in here bottoms against the shaft before the pulley is clamped, leaving a pulley that feels tight on the driver and is not actually held — which shows up as a pulley turning on its shaft under load, usually blamed on the belt.

Compatible Models for the Screw M5 x 10

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

When to replace it

• The thread is stripped, crossed or galled.
• The drive recess is rounded out.
• The screw has worked loose in service.
• Corrosion has seized it in place.
• The pulley or belt is being replaced — fit a fresh screw with it.

Fitting notes

Remove the battery pack before starting. The screw clamps the pulley with its washer (part# K73122640). Tighten firmly — this joint transmits drive torque. Turn the pulley by hand afterwards and confirm it is solid on its shaft with no rotational play before fitting the belt.

What does this screw do on the Tornado Tempest?

It secures the brushroll belt pulley to its shaft, clamping the joint that transmits drive from the belt to the brushroll.

The Tornado Tempest TV400-W26-U wide-area cordless carpet sweeper, where it is used on both the brushroll and filter and blower assemblies.
