Good news on the new belt and related parts--its not a horrendously terrible job. Access behind the fan blades is a bit limited so its a good thing this needs done infrequently.
Also a great idea carrying at least and extra belt should the existing one break.
There was a time I was removing and reinstalling the belt chasing another problem so finally broke down and bought this tool set: https://www.amazon.com/dp/B0002WSFTO...dDbGljaz10cnVl
Its remarkably useful, not overly priced and you'll thank yourself every time its used.
It's also small enough it can be stowed in minimal space giving it another advantage IMHO anyway. I don't leave home without it.
