Every part on the top part assembly shared by the Tornado CVD 38/2 (91440) and CVD 48/2 (91442) dual-motor HEPA uprights. Both machines use the same top part sheet and the same seven parts, so one page serves both.
The diagram below is for reference only — it has no clickable dots. Tornado render of the top parts sheet carries the rendering house’s credit printed across the drawing itself rather than in the margin, so we have trimmed the lower edge to remove it and have not placed hotspots on it. All seven parts are listed in the table below with their callout numbers from the factory sheet, and each row links to its product page. We have asked Tornado for a clean render and this page becomes a fully dotted diagram the day it arrives.
This section covers the electrical top of the machine — the PC board, the grounding strap and earth label, the insulation sheaths over the wiring runs, and the clamp and screws that hold it all in place. The parts that differ between the two machines are all in the brush head and the accessories, which have their own pages for the 15-inch CVD 38/2 and the 19-inch CVD 48/2.
7 parts. The numbers in the first column are the callout numbers printed on the top part drawing. This sheet is identical on both machines — same part list — so a part ordered from this page fits the 15-inch and the 19-inch alike.

Frequently Asked Questions
Why are there no clickable dots on the diagram?
Tornado render of this sheet has the rendering house’s credit printed across the artwork rather than in the margin below it. We trimmed the lower edge to remove it, which is enough to publish the drawing but not enough to place hotspots accurately, so the diagram is shown for reference and every part is linked from the table instead. We have asked Tornado for a clean render and the dots go on the day it arrives.
What do the numbers in the first column mean?
They are the callout numbers printed on the top part drawing. If you have the printed parts book or a copy of the diagram, the number in column one is the number on the drawing.
Is this page for the 15-inch or the 19-inch machine?
Both. Tornado publishes one top part sheet for the CVD 38/2 and the CVD 48/2 — same diagram, same seven parts — so anything ordered from this page fits either machine.
What is on the top part assembly?
The electrical top of the machine: the PC board, the grounding strap and earth label, the insulation sheaths that protect the wiring runs, the clamp that secures them and the screws that hold it together.
