On power up yesterday, I experienced a belt failure. 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

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.
