I use a gates multi-v and bought another this year (same part number) to change it out this year.  But the new one is at least 1cm longer than the old one, and would require a whole new alternator thension arm to take up the slack.  So the old one is still there because I don't have time for the extra work.  My guess is that they run in batches and on batch may be very different from the others..

My first dual belts were from two different manufacturers, and were very closely matched. Worked fine for 100 hours; then I changed them ‘just because’. I bought two Gates of the same part number, and they were excellent match.  They have about 100 hours and still look good.  I’ll run these longer.

ED & other dual Gates belts users ( including myself ) at our last chapter fly-in two gyro planes came in & the owner/designer/builder was telling Greg & I about a company that makes heavy-duty  "matched "  v-belts for his gyro drive sys., point is they are matched, one of our belts is stretching differently than the other ( one is loose other is tight ). Greg is going to purchase a couple of belts for our 13B stock 70A  Mazda Alt. with under-drive dual v-belt sys., will let you know as soon as we know.  David R. Cook  RV6A  Rotary  last rivets now installed ( Data plt. ) slapped in the face by the economy so moving very slow.
