cbogie Posted January 12, 2022 Report Posted January 12, 2022 Has anyone recently been successful in finding a source for overhaul on the built-in Scott regulator in the Bravo? Part number 801765-00. I have found several for sale but with tag dates that are a few years old. I have also called aviationoxygen.com (Phoebe, the "oxygen lady") but they are unable to overhaul at this time. There is nothing wrong with mine but I suspect it has not been overhauled since it was made. Bottle is out for hydrostat and I wanted to get both done at the same time. I realize there have been several threads but I was wondering if anyone had service recently? Quote
carusoam Posted January 13, 2022 Report Posted January 13, 2022 Let’s see if Doc is around… @M20Doc (Scott oxygen regulator OH resource question… above) Best regards, -a- Quote

cbogie Posted January 13, 2022 Author Report Posted January 13, 2022 Thanks for the lead. They have inspection capabilities but NOT overhaul. Ill keep looking. Quote

Where are you located? Edit: Did some research for you. Sent you a PM here. Let's talk today...the earlier the better, as I'm starting a 4-day trip around 1500ET today but can chat between connections. Steve Edited January 14, 2022 by StevenL757 Quote
cbogie Posted January 14, 2022 Author Report Posted January 14, 2022 Found C&L aero in Redding Ca. They have overhaul capabilities. Jeff quoted $625 for the pressure reducing regulator ( with the on/off valve) and $1100 for the altitude compensating portion. Also commented that altitude compensating portion is unlikely to need overhaul. He reported that due to a DOT ruling, our spun kevlar bottles can now be extended to 5 years between hydrostat testing ( not 3 years as before). Quote

PilotX Posted January 14, 2022 Report Posted January 14, 2022 I belive aerox will overhaul them too. I forget the quote but that seems about the same as I recall. Quote
kortopates Posted January 14, 2022 Report Posted January 14, 2022 I believe they only overhaul the first stage and then perform a functional test on the altitude compensating second stage. If it doesn’t pass then they replace with an exchange unit. Total is at about $1100 IRC.C&L Aero has excellent customer service and very quick turnaround.Sent from my iPhone using Tapatalk Quote
LANCECASPER Posted January 15, 2022 Report Posted January 15, 2022 A theoretical question: Since our 5 year hydrostatic test is due to the fact that DOT certified shops can’t legally fill a bottle that hasn’t been tested in the past 5 years, what if a person was to fill their own onboard in their hangar? My reason for asking is that (1) it’s a hassle to get out and re-install but mainly (2) that you take a system that doesn’t leak and when it is put back together often leaks. Quote
carusoam Posted January 15, 2022 Report Posted January 15, 2022 Tanks change over the years and number of cycles… essentially they get work hardened. each material has specific elasticity characteristics … The safety recommendation keeps it from failing with large safety factors. Aluminum dive tanks get a reduction in max pressure after a set number of years… looks like there is a known status…. and many unknown possibilities… probably safe, but not known to be safe… PP thoughts only… -a- Quote

We’ve all suffered from that one. But very occasionally it’s the high pressure o-ring or a low pressure fitting needs replacement. An experienced tech will check for these.Sent from my iPhone using Tapatalk 1 Quote
