I took my monster Makita 5200 compressor to the job today. When I got home, just for the heck of it I unscrewed the fill cap thinking it would have a dipstick on it. Nope, it's got a site plug with a red dot in the center to show the fill level.
I bought this compressor around Christmas time, a little before. My 1993 Emglo was kicking the bucket, needing a start capacitor and a pressure switch. Who knows how much rust was on the inside of those twin tanks, so find the repair parts might not make that good of a deal. I needed a compressor, like it right now. It died while I was finishing up 200 ft of quarter round. Had to buy a compressor.
Got a really good deal on this compressor and it was only $160 bucks at a pawn shop. New ones at the time for costing $350 to $400. It's much more compressive than I need for work but I found that it now allows me to use some air tools and not just staplers.
Why would I not check the oil level in a new to me, used compressor? That should have been the first thing I did when I bought it.
On the outside, the compressor looks fantastic. At the pawn shop I plugged it in and both gauges slowly rose up to 140 lb in perfect synchronicity...... Is that a word?
This is a 3 horsepower compressor in the pawn shop it started easily with a 50 ft 16 3 cord outside the building. That right there sold me on it.
I had to also looked at ratings on this unit and it's like top of the list, top of the heap.
Anyway before unloading it out of the truck tonight, I unscrewed the fill cap and it didn't have a dipstick so I looked at the site plug and it was just totally black. I had no idea if it was empty or overfilled so I put a plastic container underneath it and pulled the drain plug. Thick goo, almost resembling gear oil, came out of there. It smelled like used motor oil.
Compressors don't have thick oil. They also don't have black oil. The compressor runs perfect so I hope nothing is worn inside of it.
I let the oil drain for 10 minutes and tipped it on its side to get every drop I could out of there. I had a quart of senco synthetic compressor oil so I filled that up to the sight line with that. I plugged in the compressor and allowed it to fill up then unplug it and flush the tank. I looked at the site plug again and now it looked like it was low so I added some more oil. I pumped up the tank again and flushed it and I did that two times. Then I checked the oil a second time and it seems foamy.
Looked online and show me oil seems to me from high humidity and temperature issues or overfilling of the oil in the crankcase. It's been sitting in the carport for 2 hours. It was obvious that I overfilled it. I have a friend designed for mixing fuel for two cycle engines and I use that to suck out the excess oil. It's now slightly below the red dot in a sight line, not slightly above it. I'm sure it will be fine, it was just kind of a surprise to see the synthetic oil turn foamy that fast. Maybe it's compatibility issue with the thick oil that I drained out. I still have enough Senco oil to refill the crank case a second time and use my first fill as a flush.
I got reading stuff online that semco and probably other manufacturers send a break-in oil which is supposed to be changed soon after you start using it.
If the oil was that thick, could this be the breaking oil from 2008?
Nobody is that stupid, right?
