Tornado Brush Head Motor K46130090

The brush head motor (part# K46130090) is the dedicated brushroll motor on Tornado dual-motor HEPA uprights — Tacony catalogues it as the brush head motor for CV/CVD 38/2 and 48/2.

This is a genuine Tacony OEM part. It appears on the brush head sheet of each dual-motor machine.

Compatible Models for the Brush Head Motor K46130090

• Tornado CVD (current): CVD 38/2 (91440), CVD 48/2 (91442)
• Tornado CV (earlier): CV 38/2 (91415), CV 48/2 (91419)

The brush-head motor is what makes these machines dual-motor: one motor for suction, this one for the brushroll. PartSmart lists it on all four dual-motor HEPA machines across both widths.

What the brush head motor does

It drives the brushroll through the belt, independently of the suction motor. That separation is the whole point of a dual-motor machine: the brushroll keeps its speed under load instead of bogging down, and the suction motor is never asked to do two jobs at once.

Signs it needs replacing

Replace it when the brushroll will not turn with a known-good belt, when the motor hums without turning, runs hot, or cuts out after a few minutes, or when it has become noticeably noisier. Burning smells or visible scorching are conclusive.

Installation and fit

Unplug the machine. The motor comes out of the brush head once the belt and its fasteners are released; note the wiring before disconnecting it and check the belt and bearings while everything is apart — a failed motor often takes the belt with it.

Frequently Asked Questions

How do I tell the brush motor from the suction motor?

If suction is normal but the brushroll will not turn, it is the brush side — belt first, then this motor. If suction is gone but the brushroll turns, it is the suction motor.

Does it fit the 19-inch machine too?

Yes. The same motor is listed on both the 15-inch and 19-inch dual-motor machines.

Is it worth replacing on an older machine?

On a machine with a sound body and good suction motor, usually yes. Weigh it against the machine value.

Does it come with the belt?

No. The belt is K63484600.
