After having an HW-19 for about 20 years I just got an Aries Extended. While I have very little time on it one thing that has baffled me is belt tensioning. The motor assembly can be positioned anywhere you want so you could have very light tension or way too much, whereas the HW-19 has a fixed distance so belt tension is constant. Could too much tension be the reason why Gregory_earl had premature failure? My Aries manual says nothing about positioning the motor for proper belt tension. I would assume the Scout is in the same predicament. For reference I have positined my motor so the gap between the motor and the cutout in the plinth is equidistant.
