Tornado Tempest Main Cover Hinge K50356100

The Tornado Tempest main cover hinge (part# K50356100) is the swivel arm the main cover pivots on. Tacony lists it as Hinge, Main Cover; the parts book calls it a swivel arm. Two are fitted, one at each side, and between them they carry the cover through every emptying cycle the machine sees.

The hinges do more than let the cover open. They set where the cover lands when it closes, which is what decides whether the gasket seals evenly all the way round. A worn hinge lets the cover drop slightly out of position, and the seal goes first at the corner furthest from the strap — so a suction complaint that turns out to be a hinge is more common than it sounds.

Compatible Models for the Main Cover Hinge

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

Symptoms that point to the hinges

• The cover does not land in the same place twice.
• One side of the cover sits lower than the other when closed.
• Play or rattle at the hinge when the cover is lifted.
• The cover binds or catches part way through its travel.
• Visible wear, elongation or cracking at the pivot.

Replace them as a pair. They wear at the same rate, and a new hinge on one side against a worn one on the other puts the cover back out of square — which is the fault you were trying to cure.

Fitting notes

Remove the battery pack before starting. Each hinge is secured with M5 x 35 screws (part# K73031100) and washers (part# K73122820). Support the cover as the second hinge comes off. On refitting, close the cover before finally tightening so the hinges settle into their natural position, then check the gasket compresses evenly all round.

Frequently Asked Questions

What does the main cover hinge do on the Tornado Tempest?

It is the swivel arm the cover pivots on. Two are fitted, and together they set where the cover lands when closed, which determines whether the gasket seals evenly.

How do I know if my cover hinges need replacing?

If the cover does not land in the same place twice, sits lower on one side, rattles when lifted, or binds part way through its travel. Visible elongation at the pivot confirms it.

What models is the main cover hinge (part# K50356100) compatible with?

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

Should I replace both hinges together?

Yes. They wear at the same rate, and fitting one new hinge against a worn one puts the cover out of square — which is usually the fault you set out to fix.
