Oil Lines, Exhaust Pipe, and Cleaning Day
TLDR
- CLeared out an empty crate
- Tightened up oil line under engine
- Tightened up exhaust pipe
Details
Cleared out empty crate
As more and more parts are moved from the parts crate to the airplane, I combined the remaining parts to a smaller box and took apart a huge crate that’s taking up the space.
The crew that built this crate must be really proud of their nails because each side must contained 20+ nails. Took me (and a pry bar) a while to take apart the crate.
Tightened up oil line under engine
In the afternoon after the workout with the crate, I worked on tightening the oil line under the left side of the engine.
To get to this connection, I have to remove part of the exhaust pipe connected to the #2 cylinder. It’s 2 M8 locknuts and 2 M5 regular nuts. Once the exhaust pipe is gone, I was able to get a wrench to tighten the connection. Then I installed new M5/M8 nuts at 10nm and 12nm correspondingly.
Tightened up exhaust pipe
I finally tightened the bolts holding the exhaust pipe in place permanently. There are 2 clamps 2 bolts, but I ran into issues with each of the bolt.
For the bolt deeper in the exhaust, I’m not sure if the bolt is defective or the nut is defective. As I turned the nut to tighten the clamp it chewed up the all the threads. I couldn’t get the right torque, and I couldn’t undo the nut because the threads are shot.
I had to cut the bolt off with the angle grinder and get a new bolt and new nut. The second time it clamped to 10 nm properly.
On the other clamp (the one on the outside), it’s too big for the pipe. Before I could fully tighten it, the 2 ends of the clamp already touch each other.
So I put the clamp on a grinder and shaved off a significant chunk of the material from the clamp.
