Firewall Forward - Part 1

With my engine due to arrive in the next few weeks I began the installing hardware I had on hand from the kit as well as a few parts that ship with the kit from MidWest Panel Builders.

 

The overflow bottle was installed as well shunt and shunt cover.

The shunt cover is made from very brittle plastic and I can see why others have broken theirs during assembly or simply run into it and cracked it.

This will likely get replaced with a 3D printed version with an inspection cover in the future.

The oil reservoir was installed after powder coating, probably a little overkill because the majority of it is covered by the reservoir itself.

The brake reservoir that I received with my undercarriage kit comes with a mounting plate so it can be riveted to the firewall but unfortunately my bracket was bent backwards and didn't align with the holes pre-drilled in the firewall.

I ended up purchasing a new one from Matco directly as it was only a few dollars plus shipping and the problem was solved. MCR-002

Next up was the battery tray, that after a visit for powder coating it was assembled and mounted to the firewall.

Next I moved on to the NaviFlow Fuel Manifold sold by Aerospace Innovations.

I order one of these after seeing it in person at MidWest Sky Sports.

The kit also comes well packaged and has everything you need to install it.

I used the template to overlay on the sound deadening material so I could make a pattern to cut away the material so the back-plate can be directly mounted to the firewall.

The sound deadening material cuts easily with a sharp razor blade, from there I slowly removed the material to tried and get as much of the adhesive backing off at the same time. I failed...




For the adhesive that remained, I used some adhesive remover and plastic razor blades from Amazon to scrape the rest off.




 



The kit didn't come with instructions at the time so I called Henry at MidWest and confirmed that the template should be shifted to the left up against the stiffener as shown.

Next I match drilled and up-sized the holes and installed M5 rivnuts with JB-Weld to secure them in place.


 

 With the adhesive cleaned I was able to test fit the back-plate against the firewall.

The last part I had available was the circuit breaker block that mounts to the firewall and comes in the wire harness kit from MWPB.

I used the breaker block to mark the mounting location on the firewall and cut away the sound deadening material.

I reviewed where others had their circuit breaker boxes installed and considered where the wire harnesses which are the two holes to the right protrude allowing enough space for wiring the individual breakers.

I match drilled the mounting holes through the firewall and used M5 rivnuts with JB-Weld to secure them in place.

Propeller Installation

It was finally time to install the propeller on the engine, this has been a long time coming.       The blades are unpacked one a time and i...
