Tornado Tempest Side Broom Bolt M12 x 56 K53181070

The Tornado Tempest side broom bolt (part# K53181070) is the M12 x 56 bolt that carries the side broom arm (part# K50979600) in its height adjustment bracket (part# K50963980). Tacony lists it as Bolt 12×56, Side Broom.

M12 is by a wide margin the largest fastener on the Tempest, and the size tells you what this joint is being asked to do. The side broom arm is a cantilever carrying a motor and a brush out past the machine body, and every impact against a wall or a table leg is reacted through this single bolt. It is a pivot as much as a fastener, so its shank condition matters as much as its thread.

Compatible Models for the Side Broom Bolt M12 x 56

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

When to replace it

• The shank is scored, worn or visibly bent from an impact.
• The thread is damaged, stretched or galled.
• The head is rounded and cannot be driven cleanly.
• The side broom arm has developed play at its pivot.
• Corrosion has seized it in the bracket.

A bent bolt here is worth taking seriously. It usually means the arm took a hard knock, so check the arm and the height adjustment bracket for distortion at the same time rather than fitting a new bolt into a bent assembly.

Fitting notes

Remove the battery pack before starting. The bolt passes through the height adjustment bracket with its washer (part# K73120120) and locking ring (part# K73430830). Note the order of the stack before dismantling. Tighten so the arm is retained without clamping the pivot solid — the height adjustment has to move. Run the adjustment through its range before returning the machine to service.

Frequently Asked Questions

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

It carries the side broom arm in its height adjustment bracket, acting as the pivot for the whole side broom assembly. At M12 it is the largest fastener on the machine.

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

If the shank is scored or bent, the thread is damaged, the head is rounded, or the side broom arm has developed play at its pivot.

What models is the side broom bolt (part# K53181070) compatible with?

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

My side broom bolt is bent — what else should I check?

The arm (part# K50979600) and the height adjustment bracket (part# K50963980). A bent M12 bolt means the assembly took a hard impact, and fitting a new bolt into a distorted arm or bracket will not fix the geometry.
