Question about Scubapro MK25/G250 Hp Regulator
I am a Scubapro Technicician. I received 2 1st MK25 stages for regular maintenance. Owner confess never get a maintenance in 6 or 7 years. Everything OK when I finish them. Intermediate pressure OK. When he was in the water extreme noise coming from first stage and a leak. Abort dive. He brought me back both regulators (same problem). Then I realize they did not have O´ring in piston, between bushing (10600135) and piston. This O´ring is piece number 01050360. I do not know why regulators did not have it, or why he did not have same problem before. Have you heard about it?
Did you check your bulletins from scuba pro ? depending on the actual year of mfg ( you can call scuba pro and give them serial number )
there was a retro fit kit made for the mk 25 first stage of you send me your email i will send the bulletin to you
other wise if you wew working from an earlier service guuide then you would notbe aware of the retro fit kits and pistons some of the earlier schematic will not show you that o ring that you were refering to
