So being cheap, or is it FRUGILE :), I have gone a totally different direction with our Pump issue on our Speedaire compressor. I removed the motor off of the Speedaire compressor and in doing so I discovered the motor pulley is spinning clockwise as I am facing the pulley. But looking at the flywheel on the pump it has an arrow that shows the pump needs to spin counter clockwise. So what I have discovered is the pump appears to have been spinning in the wrong direction since I have owned the compressor, now going on almost 2 years. If what I am seeing is correct, is it even possible to spin the pump backwards and actually get decent CFM, which it always seemed to be pumping good air as it always kept up with our 2 DA sanders. In the end though, the pump went down. I looked and the compressor has a stamp date in 1998, makes this guy 15 years old. However the motor does not look older than a few years old, very new looking. The motor is reversible but is wired for clockwise. I am thinking when the motor was replaced on the compressor, the installer did not pay any attention to the pump direction.
I ended up buying a large industrial compressor at a school auction this week. It is extremely heavy duty and everything checks out good on the pump so far. But it came with a 3 phase motor so I am putting our 7.5 hp single phase motor on it tomorrow and we should be back up and running with compressed air. I have both motors in my truck right now and will be visiting with Belt and Pulley business in San Antonio tomorrow so they can fit me with the proper sized pulley on my single phase motor. In looking at the new to us pump, I discovered the arrow on the pump pulley points to turn counter clockwise that is why I paid close attention to the motor rotation.
Here is our new compressor, it will be plumbed up to our 80 gallon Speedaire tank also to add air storage capacity.
