stupid dryer belt tensioner design

I just did this too....had a roller squealing bad, took it all apart and lubed them up, seemed to work well for a couple weeks, then I decided to buy new rollers and tear it all apart again....worst part was that stupid tensioner, Eight spot and I don’t leave you a lot of room, especially not to get two hands and they’re very easily. I decided to change the belt tensioner and rollers since I was in there, it wasn’t too bad, and I believe most machines are the same. I’m sure it would’ve cost me way more if I had a repair man come out, hopefully it’s good for awhile now
