Here at Phoenix, we get a lot of calls to 1-800-776-9315. People wanting to make sure they have found the right Genuine OEM Replacement Pulley for their Scag mower, needing help measuring their pulley, or wanting to verify stock on our timing pulleys. We love these calls. We are happy to help with these kinds of questions at any hour of the day.
We also get the occasional email or phone call requesting advise on which size pulley to use when starting a new project. A recent caller with just such a question turned out to be designing an industrial automatic coffee grinder. Our intrepid innovators usually begin with, “I’ve got a 5 horsepower motor with a ¾” shaft, and I want to know what size pulleys to buy to get 300 RPM.”
