<R53> "B" specifically states: "The gearboxes for the Fisher-Price and Globe motors are not considered “integral” and may be separated from the motors".

This would imply that the window motors ARE considered "integral" since they are not specifically listed and separating them from their gearbox would be a violation of <R53>.

I don't think you have a chance on this one. Much better to re-engineer it now than wait till an inspector catches it at a regional and you have to try to kluge something together to make it legal.

Now if you buy an "off the shelf" motor IDENTICAL to the KOP window motor and take it apart and just use it's gearbox, I would say that was perfectly legal. As stated by an earlier poster, that's no different than using a drill gearbox. Just be prepared to prove to an inspector that it's NOT your KOP window motor gearbox!!
