Hi gregory,
gladly, and yes, the issues are partially not that obvious.
Still nothing from Gates, maybe you want to try yourself?
The question is; what has to be watched when adding an additional, very small beltwheel, similar to a tensioner.
(That should be the correct department:
Gates GmbH
Eisenbahnweg 50
52068 Aachen
Got that from the bicycle belt support, but without an email address, so I tried that one:
info@car-aachen.de
- no reply so far.)
That’s great if you can talk with the efneo guys in their mother’s tongue 
(But their English is also very good.)
