Annual Help (alternator and brake line)

[Skymaster337B]

The only thing those swivels need is a new o-ring. Taking it apart is easy too, small drift pin to knock out the roll pins. Then remove and replace the o-ring. But you do have to remove the swivel from the aircraft and put it in a vise to knock out the roll pins. I did this with my 337 7 years ago and it still working just fine.
