[DML] Re: B28F Water Pump Pulley

["David Teitelbaum" <jtrealty@xxxxxxxxxxx>]

Having 2 belts instead of 1 does not necessaraly make the set-up more
dependable. I have seen many cases where one belt gets thrown off or
rolls over and catches other belts causing them all to fail. The # of
belts is mainly a function of how much power you are trying to
transfer. If it is near the capacity of 1 belt then the designer may
either go to a method with a higher amount of power transfer (more
expensive) or just add another belt. In our case 1 belt is more than
sufficient. Just make sure it is aligned, tensioned properly, the
pulleys are not worn or bent, and replace the belt every 10 years or
so. A loose belt will quickly fail from all the heat generated. Heat
is the big enimy of a belt (usually caused by being loose). The second
biggest cause is being overtightened. This stretches the cords causing
them to break. As you can see setting the tension on a belt is important.
