Hi everyone! This is my 1st time posting on this forum. Hopefully I can get some help. I am working on a Joy D18504 Bumper Pull Industrial Air Compressor. This thing is super old and I am wondering where would I get parts for this? I doubt my local Napa can help because I have no part numbers. Does anyone on here have a compressor similar to this and knows where I could get parts for it? My 2nd question, this picture I attached to my post is not my compressor but its similar. What I have circled in black, there is a rod that pushes in and out on the compressor intake that controls the throttle on the engine that drives the compressor. When the compressor shuts off, the air that is still in the system pushes a lot of oil from the compressor out of that hole where the rod is and makes a big mess! I tore it apart and there is no seal or anything that seals it. How the heck am I suppose to fix this oil leak if there isn't a seal in it? There's no way it should be pushing oil up in the compressor intake to begin with. I thought about chaning the pop off valve 1st and see what happens. Maybe after the compressor is shut off, the pop off valve isnt releasing all the air still stuck in the system fast enough and it has no where to go but into the intake? If anyone has any experience with this kind of air compressor and can point me in the right direction I would greatly appreciate it! Thanks so much!
