bending a V-belt in that fashion will make the jugs rip off eventually..

v-belts are not made to be tensioned from the rear..

lawn mower belts have no lugs, and are designed to be tensioned from the back side..

lawn mower belts are WAY different in design than automotive belts..

i agree, they may be design differently or so "The Man" wants us to think, i will chuak this up to r@d project and see how long it lasts next step may be to get a mower belt to see what happens you never know untill you try .
its not a big deal to put a belt on if it comes off and alt lite will tell me when it comes off.
I do know that i dont hear that belt sqeal anymore

Right on.  I tried a few belts and a reverse-flex idler; but I took the setup off for a re-think, as the lugs were coming off in cold weather.

Keep spares and tools with you... and please keep us posted.  Thx.

ive used lawn mower belts on cars before without issue..

i WOULD NOT HESITATE to running a green belt on my car if i had a reverse tensioner setup..

The spare belt I carry is an A34. It's a bit wider than the stock belt, but it has no lugs, and it was dirt cheap.
