I recenttly purchased a Coltri compressor block, no engine or frame, just the compressor, piping and filters. The previous owner could not say anything about running hours or anything else, except that all parts are there and the shaft can be turned normally. The primary purpose is to make it running again, secondary purpose is to get me introduced in the world of compressor maintenance. I do not have practical experience with compressors but I have a fair ammount of mechanical engineering knowledge and I own a garage full with a lot of tools. I do plan to dissasemble it completely, clean it, change whaterver is deffective or worn and put it back together.
However, I need some issues to be clarified, so here comes my humble request for help from anyone who can and is willing to offer it.
The compressor is presumably MCH-6 but I could not find a plate with model or fabrication year. However, it is a bit different from other MCH-6 pictures found on the web:
-the pressure gauge is not mounted on the moisture sepparator, is mounted at the end of the filling hose
-the bleeding point for oil is not near a piston, on lateral, it is under the main pulley
-the configuration of the first stage and the intake filter is a bit different in position than current compressors
Question: can anyone speculate what model is it, what year and where can I download a schematic of the compressor if it is different that current models?
Regarding the service, the compressor is full of oil spilled everywhere, this is due to transport. I have to clean it on the outside as well as on the inside after dismantle it.
What should I use to clean it? Is 100% acetone ok? I use acetone to clean surfaces in preparation for TIG welding, so I have some stock and I could use it for cleaning.
I attached some pictures with it. Sorry for bad quality, I cannot make better ones right now, but this weekend I will get to a DSLR.
