From what i’ve read, it seems there isn’t a whole lot of difference between gear driven and belt driven these days. Belt might technically be the best choice, but it appears to be a slim margin, if that. Again, from what ive read… i have a gear driven. Call Bob at Pressure Tek, or Russ at Southside, and they can tell you what you need if you want to switch to belt drive.
Why are you replacing yours? Is it bad?
