Could somebody please tell me what the proper way is to evaluate floating piston wear. The Bauer workshop manual for big block compressors are very detailed about ring wear but does not adress the floating piston.
I am busy restoring a Bauer KA20 that was sold as scrap due to suspected consequential damage from an hydraulic lock. After strip down right to the sump I found all was as well as could be expected of a compressor that only ran 600 hours since 1976. What is worrying me at this stage is how the performance of this compressor could have dropped to the stage where such radical damage was suspected so I am trying eliminate all possible problems.(did I mention that the same "agent" sold them a new compressor shortly afterwards?)
Included are some photos. I had to take it in 3 sections so please have a look at the file names for orientation. (I am still working towards buying that DSLR camera when I can afford a housing as well) The compressor stopped working in 2005 and was standing outside for the last year. After I cleaned it the piston was sitting tight in the sleeve with the barrel tilted about 75 degrees but in oiled condition it slips back into the sleeve about an inch at the same gradient.
