Compressor
I decided to take the pump apart after getting it home. The source was specific on it running quiet and the oil was clean and not sparkling.
Upon disassembly a broken check valve was discovered. The parts on the right were still in the head, the other part of the retaining plate was nowhere to be seen.
I decided to look further down stream and eventually found the other pieces. They were lodged in the check valve / un-loader valve. The dark brown piece in the valve is part of the check valve that broke. The restriction was enough to boost the current draw close to the trip point of the breaker. When the tank pressure got close to the cutoff point the current was high enough to pop the breaker.
The shiny cylinder was the one with the broken check valve. I found no scoring or other damage in the pump at this point but elected to pick up a rebuild kit that included bearings, rings, gaskets and all the hardware.
I had to make a puller to remove the flywheel on the compressor. Emglo has a very strange to me way to affix the flywheel. The shaft is not tapered and has a round dowel pin that bisects the shaft and wheel. A LARGE amount of heat and a very strong puller are needed to get the flywheel removed. I fabricated a plate to bolt my trusty harmonic balancer puller to and three plates went on the backside of the flywheel. There were no places to grab using a conventional jaw puller. As it was it took my big 1/2" Ingersoll impact to get it off. Reinstallation was also a fun project! I heated the hub of the flywheel with the rosebud tip on the big "blue wrench" and used my carburetor choke cooler to cool the shaft. A 5/16 bolt was used to help align the hole for the pin during the installation.
I made some anti-vibration feet for the compressor to keep it from walking around and to allow it to be leveled as the place I located it was slightly sloped. The rubber pads have kept the vibrations into the slab at a minimum. I added a 220V contactor that is driven by my ISY Home automation server. The control module for it is the little white box in the top of the housing. I have a wireless remote in the shop that allows me to turn on/off the compressor with a push of a button. There is a secondary ISY module in the bedroom with a small neon nightlight that alerts me if I have left the compressor turned on. No more getting woken up in the middle of the night by the compressor coming on. New hoses, belts and a gauge completed the build.
