Re: Possible to extend output shaft on WCP Gearbox?
You have a Design choice of v belts, synchronous belt, poly cord, and chain.

Using 5M HTD belt on small pulleys with only 12 teeth engaged and the small 1.5" turning diameter is not the intended or recommend use. The fact that you broke 9mm wide belts, suggests you probably were just getting by with 15mm belt with very little margin.

These HTD belts have some elasticity which reduces the effective number of teeth in mesh on the pulley. This effect is magnified when the number of total teeth is under 30.

Going to a 3M belt would provide additional margin at a given pulley diameter, as there would be more teeth engaged.
