Luckily, I still was on the ground. The belt had about 80 hours on it but dated back to when Stratus changed from two belts to one (about three to fours ago?). Upon examination, the "teeth" on the inside of the belt separated from the rest of the belt, thus causing the belt to lose grip of the pulley and resulted in a failure. When I called Mykal, he said that "materials degrade over time and the belt should be changed out every year". This, of course, is contrary to his published maintenance schedule for this item. Given the critical nature of this part and my recent experience, I would have to agree and recommend a yearly change out of the belt. I can't imagine the end result of a belt failure over hostile terrain...=0D=0A=0D=0AJohn Karnes=0D=0AN601JK Zenith 601HDS=0D=0AWashington ________________________________ Message 2 _____________________________________ Time: 01:22:33 PM PST US Subject: RE: Stratus-List: prop drive belt failure From: "Hinde, Frank George (Corvallis)" --> Stratus-List message posted by: "Hinde, Frank George (Corvallis)" Great! and Mykal will be writing to inform all his customers of this change will he? To be fair to the belt I am surprised it failed...Was it the single 55mm belt?...Thats a lot of work and it's the first failure of a single belt I have heard of. If the belt truly needs to be changed every year then I doubt he will be selling many motors from now on.....Everyone will buy a Rotax.
