Battery Cables

January 10, 2019 –  I continued work on the battery cables because I’m borrowing the crimper and the guy said he’d need it back.

I had to order some 1/2″ heatshrink in red and black to fit over these terminals. Once I had that, I made the cable from the contactor to the starter, and the ground from the battery to the firewall.

These pictures of the starter cable ARE NOT final installation, they are for routing and fitting. Hopefully this location will work.

Miscellaneous Firewall Forward stuff

October 17, 2018 – I realized it’s been a while since I posted an update, so here goes…

Engine control cables

I started assembling the parts for engine controls: throttle, mixture and prop. I started with the mixture, since it’s a fairly complicated bellcrank system that reverses motion. The first problem that I ran into was that the mount bracket for the bellcrank does not fit as advertised on my engine. Right where this bracket is supposed to go, there is a drain plug in a boss on my Superior cold-air sump.

I found online where someone else had this same problem. They started by grinding down the height of the plug. So I did that, but the boss that the plug is in will not allow the bracket to sit in place.

I decided to trim the bracket until it does fit. After everything is installed and works, I’ll take the bracket off and make a new one. You can see that I removed a lot of material. That’s fine.

So I assembled the bellcrank and moved on.

I measured for the three cables, since I am using a throttle quadrant instead of the traditional push-pull controls supplied by Van’s. I ordered some from Van’s and just got them today. I also drilled the holes in the firewall at the three recommended locations. They’re just 1/2″ right now. I’ll take them to final size when I start test-fitting the cables.


Fuel Flow Transducer

I figured out where I’d like to mount the Red Cube. It will be inline between the servo and the flow divider, and I’ll mount it on the engine mount behind #3 cylinder. I had the long fuel hose that goes there…I sent it to Tom Swearengen at TS Flightlines. He took care of me. I’m a big fan…

Oil Temp Sensor

I installed the oil temp sensor as required…

Engine Electrical

I’ve been slowly working on cables for the battery, starter, etc. The only picture I have right now is the copper bar between the contactor and the relay. I replaced the one bar I had with two that total .125″, which is closer to the plans.

I got in touch with a guy who was in town and bored (he posted on Van’s Air Force). He was looking to see if anybody needed a hand with anything. So he came over today to visit, and we took care of a short list of items I needed an extra pair of hands to get done.

We installed the firewall pass-thrus, and I needed to remove the manifold on the firewall so I could get fittings in it. We removed it, installed the required fittings, and reinstalled it. If I ever have to take that manifold off again, I’ll install nutplates.
