Tornado Tempest Hinge Washer K73122820

The Tornado Tempest hinge washer (part# K73122820) is the washer used at the main cover hinge pivots on the TV400-W26-U cordless sweeper, with four fitted. Tacony lists it as Washer, Hinge and the parts book records it as a disk — the same component named two ways.

At a hinge a washer is a bearing surface, not just a load spreader. The swivel arm turns against it every time the cover is opened, so it takes rotational wear rather than the static clamping duty a washer does elsewhere on the machine. That is why the Tempest specifies a particular washer here rather than reusing one of the thirteen others in its parts list.

Compatible Models for the Hinge Washer

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

When to replace it

• The washer is scored, grooved or has worn thin at the pivot.
• The cover hinge has developed side play.
• The washer is dished or has bedded into the surrounding material.
• It has been lost during a previous strip-down.
• Any time the hinges are being renewed — fit new washers with them.

That last point is worth following. New hinges (part# K50356100) running against worn washers wear quickly, and the washers cost a fraction of the hinge.

Fitting notes

Remove the battery pack before starting. The washers sit at the hinge pivots with the M5 x 35 screws (part# K73031100). Note the order of the stack as you dismantle. Do not overtighten — the hinge has to swivel freely, and a washer clamped solid will bind the cover instead of bearing it. Check the cover swings smoothly and lands square before returning the machine to service.

Frequently Asked Questions

What does the hinge washer do on the Tornado Tempest?

It acts as the bearing surface at the main cover hinge pivot. The swivel arm turns against it each time the cover is opened, so it takes rotational wear rather than static clamping duty.

How do I know if my hinge washers need replacing?

If they are scored, grooved or worn thin at the pivot, if the hinge has developed side play, or if a washer is dished. Renew them whenever the hinges themselves are being replaced.

What models is the hinge washer (part# K73122820) compatible with?

The Tornado Tempest TV400-W26-U wide-area cordless carpet sweeper. PartSmart lists it against the Tempest alone, and four are fitted per machine.
