If it's anything like my HW-101, you have to remove the PA cage, then loosen
a fastener inside the cage. Then, the shaft will pull out far enough to get
the "O" rings over the shaft and pulley. Then just shove it back in reverse
order. No problem at all.

The idea of O rings is great. I have done it many times, and they always
work. I have on one occasion taken a broken belt to an auto parts store,
where they matched the thickness, and measured the length, cut it, and glued
it together. It's still working after about two years.

Good luck
