Completed engine wiring, plumbing, oil cooler

 

Assembled the oil cooler inlet and tray. Trimmed, deburred, and primed all the parts and then riveted them together. Glued the seals in place and sealed all the gaps with RTV. Installed the AN fittings into the oil cooler. Bolted the tray to the firewall and engine mount. Then mounted the air cooler and inlet. Connected the feed and return lines to the oil cooler.

 

Wired the EGT sensors, CHT Sensors, and Fuel flow sensor.

 

Created a hose for the manifold pressure sensor using Aeroquip AQP hose and reusable connectors. Ran that hose to the sensor block from the primer port in the #3 cylinder head. Also ran a line from the sensor block to the MAP port on the right PMag. I the manifold pressure, fuel pressure, oil pressure, and oil temperature sensors using crimp on, fully insulated, quick disconnect terminals.

Installed prop governor, fuel flow sensor, and sniffle valve

Installed the prop governor. I wasn’t sure what hardware to use. The plans said to refer to the engine/governor installation instructions. The Hartzell instructions said to refer to the engine manufacturer’s instructions. The Lycoming instructions that came with the engine were mute on the topic. I was able to find an illustrated parts catalogue for the engine on Lycoming’s web site. It showed a washer, a star washer and a plain nut. Now I need to figure out where Lycoming keeps its torque values.

I installed the fuel flow sensor and the fuel lines from the fuel pump and to the fuel injection servo.

I installed the sniffle valve. This seemed like it was going to be straightforward. Remove the plug; install the valve. What I didn’t take into account was that the intake manifold was full of preservative oil. So now my nose gear and tire are well lubricated and in no danger of corroding.
