Greetings,
I have been working with a very generous and patient SB member here on how to service my own regs Things have been going awesome...I am doing very well with the 1st stages [all Scubapro and all MK20s]. I am just now beginning to work on some second stages [2001/2006 S600 and 2001 R380].
Tonight I was working on the S600 [2006] and I was not sure how to "tune" the balance chamber...I am talking about page 17 of the "Scubapro S600-S550 Repair Guide" second step from the top, I have Configuration B. I saw the top of the balance chamber [P/N 11600009 or #34 in the S600 schematic from 03/01]...but I was not able to easily turn it...I could pop it out of the piston, balance camber [P/N 11600010 or #36]...but was unable to turn it once installed....any tips? Also, how do you tune it per se?
This reg was recently serviced but the work seemed less than adequate...the first stages were completely dry of lubricant [they said they used Tibolube]. So, I did a disassembly, inspection, relubing [light] of o-rings and threads, and reassembled.
Afterwards, I did a rough tuning on the orifice with an in-line tool [turning 30 degrees past where free flow stops, with the lever down as to not score the seat].
Then, I tried my used Magnehelic gauge...it seemed either way too sensitive or something as I was not able to get a very clear reading [see youtube video I made below]. I am not trying to get the high score on cracking pressure [low value]...more trying to understand the method, steps, process involved so I can build my foundation of knowledge
Thanks in advance for any info
