It has taken forever and will continue to be a glacial build, but I have gotten started on my On Board Air (OBA) system. Took me about 1.5 days to build the bracket. There was a lot of install/remove cycles to make sure everything fit.
Compressor: York is an aluminum model 210. They come in Steel housings also. I weighed the steel one without the clutch/pulley and it weighed 23lbs. The aluminum housing without clutch weighs 11 lbs. So as you can see a considerable weight savings. With the aluminum York, new double pulley/clutch and bracket, it weighs 22lbs. The clutch weighs almost as much as the York.
Tensioner Pulley: No idea other than I was walking trough PNP and looking at various v-belt pulleys and spotted this one on an Isuzu PK 4cyl motor. It adjusts with the small bolt on top. That tightens the belt and then you tighten the main bolt to snug the pulley.
Bracket: Homebuilt. A lot of trial and error, but it is made out of 1/4" steel plate. I sand blasted it in a buddies blast cabinet, so that is why it looks a little weird. Aluminum Oxide was the blast media. Could be prettier, but it will be mostly hidden, so I didn't get too crazy with the finish work.
Belt: Made my measurement and went to Napa for the belt. My measurement was off the first time by 1", so I had to go back and get the next size up.
I installed everything and ran it for a week to make sure the belt would stay on and everything else was good to go, of course I didn't put power to the compressor, so it was never under a true load, so we will see. So far so good.
You can see some of my "Speed Holes." I was trying to lighten it up by removing non-essential metal.
I still have to buy the seal kit for my York, it is leaking around the "head" and of course I have to buy all of the other stuff to acutally be able to use it.
