RG hydraulic lines.
I made the first attempt to retract the landing gear today and things
could be better. As soon as the nose gear started up and the main gear over-
center unlocked I turned off the pump to check for leaks. Two of the flex
lines were leaking at the coupling. The pressure gauge had not yet moved, 0
to 2000 psi. I called a hydraulic shop in Phoenix and talked to the tech
about it and he said that rubber lines only have a usefull life of about five
years. I know that the lines twisted some when I installed the fittings, but
they are already 5 1/2 years old (I'm slow).
The shop will make up a set of steel braided teflon lines for about $175
including tax and that's less than doing it yourself as their machine crimps
on less costly fittings. New rubber lines to use my original fittings cost
$40. Comments please and/or a source for lower cost teflon lines.
Also, if your lines are a few years old you might consider having them
pressure tested. I didn't enjoy pulling out the nose gear assembly again and
cleaning up the mess.
