Tornado CVD Dual Motor Vacuum Belt K63484600

The vacuum belt (part# K63484600) drives the brushroll from the brush-head motor on Tornado dual-motor HEPA uprights.

This is a genuine Tacony OEM part. It sits on the brush head sheet of the dual-motor machines.

Compatible Models for the Vacuum Belt K63484600

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

PartSmart lists this belt on the four dual-motor HEPA machines — both current CVD models and both earlier CV models — and on no others, so it is specific to the dual-motor brush head rather than to one width.

What the vacuum belt does

On a dual-motor machine the brushroll has its own motor, and this belt is what carries that drive to the roller. It is a wear item by design: the belt gives before the motor or the bearings do when something jams the brushroll.

Signs it needs replacing

Replace it when the brushroll stops turning while the motor still runs, when you can smell hot rubber, or when the belt is glazed, cracked, stretched or has lost teeth. Belts also relax with age even when they look intact — if suction is fine and pick-up is poor, check the belt before anything else.

Installation and fit

Unplug the machine and lay it flat. The belt is reached from the brush-head underside; note its routing before removing it, seat the new belt on both pulleys, and turn the brushroll by hand a full revolution to check it tracks straight before powering up.

Frequently Asked Questions

Is this the same belt as the single-motor CVD 30 and CVD 38?

No. Those are single-motor machines with a different drive arrangement. PartSmart lists this belt only on the four dual-motor HEPA machines.

How often should it be changed?

Inspect it at every service. In daily commercial use a belt a year is not unusual.

The brushroll stops but the motor runs. Belt?

Almost certainly, though check for a jam in the roller at the same time — a belt that breaks twice is telling you something is binding.

Does it come with the brushroll?

No, they are separate parts.
