Between Kevin, Greg, and myself we got a lot done today.
Kevin and I finished up the fuel vent system which required a couple of flex lines and triming the stainless vents that exit under the strake. Nothing much new there.
While we were doing that, Greg was reinstalling the rudder pedals and brake master cylinders. Once he was done with that, we filled the system with hydraulic fluid by bleeding the brakes with an oil can.
Right away we knew there was a problem on the right brake. Fluid was leaking out of the stainless steel flex line hose fitting to the caliper. So we moved on to the left brake and that one went as expected. The pedal feels firm and feels right, but we can see there are a few small air bubbles in the clear part of the line. (BTW the wires still need to be restrained away from the pedal and master cylinder.)
No big deal, we will have to run a bit more fluid through the system to push the bubbles out. The only thing is we need to come up with a set of fittings that will allow us to overfill the reservoirs without making a mess. We will see what we can come up with.
We then went back to the right brake and disassembled the hose fitting at the caliper. We could see some damage to the fitting that I must have done when I initially fabricated the line. We tried a new fitting but that didn’t solve the problem either. Finally we cut 1/4″ of the hose off and used another new fitting and we had the leak fixed. Both brakes now are working.
Somewhere along in there, Greg and I also finally mounted the OAT probe for the G3X. Just a 3/8 hole and it was mounted.
Then we filled the oil cooler and oil sump with mineral oil. As well as torqued and safety wired the oil filter in place. First oil “change” is now in the books.
Lastly, the biggest piece of visual motivation, we got the prop extension and prop torqued down and safetied. We checked the tracking of the prop and it is dead on. Sure makes it look like more of an airplane.
