WQ Hans

 This is a picture from my Hendrickson walking beam rebush project on an International truck. The axles are off the truck and the walking beams are out to get new bushings pressed in.
 
 
This week I set out to learn about air compressor and to assemble my own mobile air compressor. This compressor is assembled from a 6.5 hp engine that I have had for a while, the engine is set up to run at 3600 rpm's and has a 3.75" pulley on it. The compressor will pump up to 145 psi but is limited right now to 125 psi because of the unloaded valve, this is the pressure. The compressor is also capable of 10 cfm, this is the flow. The air tank that I am using is a 50 gallon air tank. This setup is even capable of running a 1" drive impact gun with out having to stop to build air pressure, even when using it to take off bud wheels. The compressor just has to run for longer which isn't necessarily the best thing for this small compressor because of all the extra heat its generating.
 
This is the pilot unloaded valve. It is an unloaded valve, check valve, pressure relief valve, and throttles the engine down when the air tank reaches 125 psi.
   In this picture is the tank pressure relief valve, the tank air gauge, a shut off valve, and the air pressure regulator so I can limit air going to my air tools to 90 psi so that I don't over speed their motors. I also have fittings for a 1/2" and 3/8" air hoses.
This is the engines throttle, its hard to see the throttle control in this picture. The throttle control pushes the throttle lever one way or the other to speed up or slow down the engine, its what's called a bullwhip style throttle control. The cut in pressure is 95 psi and the cut out is 125 psi 
 
This week = 55, total = 175

  1. Ah, suspension work. Nice photo there, it looks well blocked. Thank you for your attention to safety Hans.

    Also the safety relief on the air tank. They are a must have item. Well done.
