Annual Help (alternator and brake line)

[Aeromx]

Bill,

On your brake line swivel.......I'm the mechanic that worked on Jchronic's ship and he had the description of of what we did a bit off. Never having taken the swivel fitting apart before (new or rebuilt from D. Nieser very $$) I did break the fitting. However, after breaking it I studied it and realized that besides the two roll pins there is also a internal circlip "c" retainer ring around the swivel "ball" holding it together. Once I figured that out I got another fitting off a junker 337, disassembled it properly, replaced the swivel O-ring with a new MS29513-010 & reassembled. Leak check & test OK. Has been in service for 100+ hrs on Joe's ship with not leaks. We just did the other fitting in the same matter in Feb. Keep in mind this not an "approved" repair as legally all you can do is replace the whole fitting as no maintenance info or parts breakdown (ie the o-ring #) is given by Cessna.

Thanks very much for this reply. At first my mechanics said they didn't want to get into repair (they gave it a quick try), so I started to head down the path of buying from Don. He actually shipped me two used units he had serviced, but in the meantime my mechanics had gone at mine and replaced the o-rings. Don graciously agreed to take them back from me and put them on the shelf for the next needy buyer! My mechanics did not mention the clip you describe but did say "it was tricky". They leak tested them with brake pressure overnight and no issues, so I seem to be good to go. Many thanks for your reply though. Best regards. Bill Taylor
