Tornado Tempest Battery Mount K50321850

The Tornado Tempest battery mount (part# K50321850) is the structural housing at the heart of the TV400-W26-U cordless sweeper. Tacony lists it as Battery Mount, Roller Adjustment, and that double name is accurate: this one moulding carries the 36V battery pack and also carries the roller height adjustment mechanism, so it is doing two jobs that on a corded machine would be handled by separate castings.

Everything else on the battery housing sheet hangs off it. The battery latch, the release button and their springs mount into it; the height adjustment knob, its bushing, lever and twisting bolt all pivot in it; the on/off switch and contact display sit in its face. That makes it the part you end up replacing when the machine has been dropped or run into a dock, because a crack here loosens half a dozen other components at once.

Compatible Models for the Battery Mount

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

Symptoms that point to the battery mount

• The battery pack rocks in its seat, or will not click home squarely.
• The pack drops out or loses contact when the machine is pushed over a threshold.
• The height adjustment feels sloppy or will not hold its setting.
• Visible cracking around the latch pocket or the adjustment pivot.
• A previous impact has left the housing distorted so the cover no longer sits flush.

Before ordering, check the cheaper parts it holds. A pack that will not latch is more often the battery latch (part# K50369480) or its spring (part# K63302640) than the housing itself, and a sloppy height adjustment is often the bushing (part# K51120430) rather than the mount.

Fitting notes

This is a strip-down job rather than a quick swap. Remove the battery pack first, then transfer the latch assembly, the release button and spring, the adjustment knob train and the switch and display to the new housing, noting the order of the washers and nuts as they come off. The mount is secured with M5 x 20 screws (part# K73031080), of which fifteen are used across this assembly.

Frequently Asked Questions

What does the battery mount do on the Tornado Tempest?

It is the housing that carries the 36V battery pack and the roller height adjustment mechanism. The latch, release button, adjustment knob train, on/off switch and contact display all mount into it, so it is the structural centre of the machine’s control end.

How do I know if my battery mount needs replacing?

Look for a pack that rocks, will not seat squarely or drops contact over bumps, a height adjustment that will not hold, or visible cracking around the latch pocket or adjustment pivot. Rule out the latch, its spring and the adjustment bushing first — they are far cheaper and produce similar symptoms.

What models is the battery mount (part# K50321850) compatible with?

The Tornado Tempest TV400-W26-U wide-area cordless carpet sweeper. PartSmart lists this housing against the Tempest alone, and Tacony names it as a Tempest part.
