I'm usually terrible at documenting any of the project endeavors that I've made, but this time I managed to do a little bit. For a while I had been using a small speedaire compressor w/ a 3/4 hp motor and it wasn't enough for what I needed. Ideally a 2 stage pump would be great, but god knows those command quite the premium price wise. I never have a lot of cash to dump into projects, so it was a waiting game. After about a year of biding my time I found something that would work. It was a drive, but well worth it. Someone was going to buy it, but couldn't lift it into their truck and I could see that as the motor weighed well over 100lbs.
Here is when I got it unloaded from the truck.
Really the coolest part was the motor. It isn't the original, but rather a late 30's early 40's Delco repulsion-induction motor.
The wiring was such that only one coil was running, so I got curious as to why. Long story short it's a 24 amp motor at 110v, so it tried to catch the wall on fire when I attached the other coil, go figure when you're talking about pulling from a 20 amp breaker right? So to utilize both coils properly it had to change to 220v. Before that though, I couldn't help but to see the condition of everything inside.
the nameplate after cleaning the over-paint the best I could without killing what was underneath
hinged oil reservoir cap
low and behold there were a few brass stamped tags with the wire numbers on them, so that made it easier....
The wiring was extremely brittle so I had to be very careful not to crumble more of it than there already was. I believe it is cotton/asphalt clad wire?
Another few shots of the inside. This is where the pictures stopped though because it turned into a brakeleen warzone quickly...
There was a whole slough of those guys hanging out which was not my favorite part. Cleaned everything up though and even by freak chance found that the rear wheel bearing I had laying around brand new was the same as the spun bearing in the back of the motor almost exactly, so it got a new bearing also.
Before the motor was done and put back on I had to devise a tensioning system for the belts. This is what I came up with.
bolted a piece of 2x2x3/16 onto the motor mount and threaded it for 2 5/8" bolts for positioning the motor with the pump pulley. Re-purposed the random idler pulley to act as a final belt tensioning.
I'll have to take more pictures of everything all done. Pumps up and holds 180lb pretty well in addition to running quite smoothly with proper belt tension & such
Thought it would be interesting to share, so hopefully someone gets a kick out of it
