Some more work to do....

Our working air compressor, dismantled.
Sometimes we use this compressor to "help" the main starting air compressors but for a long time now it has not enough capacity anymore.
We discovered last time (see here) that one piston ring at the high pressure side was broken and one was stuck.
So it was about time to dismantle it....
Here are the HP (at the left) and LP piston (at the right). The LP one was fine.
The HP is ready to replace with new rings. 
Sadly enough the scraper ring is very fragile and broke while we put it into place... 
So we have to order a new one....
