Tornado Complete Adjusting Wheel K45153160

The complete adjusting wheel (part# K45153160) is the genuine Tacony brush-height control, supplied as a full assembly rather than a bare dial. It is what the operator turns to match the machine to the carpet — lower for short commercial loop, higher for plush — and it is a part that gets used every shift on a machine that covers mixed flooring.

This is a genuine Tacony OEM part. It appears on the brush head sheet for both the 15-inch and the 19-inch machine, and Tacony uses the same assembly on both widths.

Compatible Models for the Complete Adjusting Wheel K45153160

• Tornado CVD 38/2 (91440) — 15-inch dual motor HEPA
• Tornado CVD 48/2 (91442) — 19-inch dual motor HEPA

Not width-specific: the same adjusting wheel serves the 15-inch CVD 38/2 and the 19-inch CVD 48/2.

What the adjusting wheel does

The wheel drives the pinion and the linkage that lifts and lowers the brush head in steps. Getting that height right is most of what determines whether a machine cleans: too high and the bristles barely touch the pile, too low and the brush drags, the belt heats and the motor labours.

Signs it needs replacing

A dial that turns without changing the height, a setting that will not hold through a pass, a wheel that binds or jumps at one point in its travel, or visible damage to the detents. Because it is supplied complete, replacing it fixes the dial, the detents and the drive together.

Installation and fit

The wheel sits under the top hood cover. Unplug the machine, remove the cover, lift the old assembly out and fit the new one, then run it through its full travel before closing up and check the head actually rises and falls at each step.

Frequently Asked Questions

Does it fit both the 15-inch and 19-inch machines?

Yes. Unlike most brush-head parts, the adjusting wheel is common to both.

My height will not hold — wheel or pinion?

Check both. A worn pinion (K50334590) is the cheaper and more common failure, but a seized or damaged wheel is what usually strips the pinion in the first place.

What does “complete” mean here?

It is the whole assembly rather than just the dial — wheel, detents and drive together.

Is there a UPC for this part?

Tacony does not publish one for this item, so we leave the GTIN blank rather than guessing a number.
