With my engine delivered and a quick inventory of all parts and condition completed, I can now continue the firewall hardware installation.
It is far easier to install of these parts prior to mounting the engine and I highly recommend this approach.
I started with installing all of the runner isolated rubber posts that will mount the engine power management module, master solenoid, and starter relay.
Engine fuse power management controller mounted.
Starter relay installed
I also needed to cut out the sound deadening material for the master solenoid and installed some M5 rivnuts with JB-Weld.
I used the based plate of the solenoid to create the template to cut out the required material from the firewall.
I used the base plate to match drill the holes and up-sized for M5 rivnuts and used stainless hardware and washers to secure the solenoid to the firewall.
Solenoid installed, there should be enough clearance for the the main wires from the battery and the attachment cams for the cowling.
I opted to leave the fuel pumps for the Rotax 915 in the factory location and with new fuel manifold installed this should keep all of the fuel lines and routing nice and neat. I will cover more of the installation of the fuel pumps wiring and fuel lines in another post.
The last part prior to installing the engine is the voltage regulator and heat sink that shipped with the firewall forward kit.
The unit was wired up to the engine fuse box and secured using Adel clamps to the engine mount.
This completed the hardware installation prior to mounting the engine.
Tip #1
During the installation of the engine I ended up removing the voltage regulator to allow more room to access the bolts for the engine. The heat sink has very sharp edges and I was frequently scratching myself on this part so it had to go and was re-installed later.
