After fixing the main wheels, there was also some things to attend to at the back. We’ve had a replacement for the ridiculously dinky tailwheel since before I became a co-owner but never mounted it. Since we were doing wheel work anyway, we decided now was the time. Replacing the tailwheel looked simple until we …
The “one thing” left to do on the Sonex was to fix the left wheel brake, which was stuck. Well, ok, the left tire also kept losing pressure. Finally co-owner Andy and I managed to get down there and jack the plane up so we could take the wheel off. We had wondered about how …
Now that the Aerovee seems to run OK, I won’t have time to work much more on it for a while. However, as part of trying to get some full-throttle time on it, I did complete a bunch of runs with different mixtures to see what the mixture distribution looks like now. These tests consist …
In the time since the engine was replaced on the plane, I’ve been able to get down to the airport every now and then and work on hooking everything up. The biggest thing to put together was the oil system. The lines to the oil filter and oil cooler had to be fabricated and I …
Finally, the engine is back on the plane! Last weekend, we borrowed an engine hoist and trucked the engine back down to the airport. With the hoist, it was pretty easy to guide it into place and bolt it up. That was all we had time to do, though, but at least now I can …
After sealing up the engine guts, I had one more task to perform in the shop before the engine goes back on the plane. Based on what our bearings looked like, it was obvious that the lack of an oil filter had not worked to our advantage, to put it mildly. Deciding to add an …
This is it, the final post in the engine guts series! After I had worked out how to do all the rocker geometry setup, as described in the previous post, it only took a morning to do it for the other head. Amazing how much more efficient things are when you know exactly what has …
After setting deck height, it was time to set the valve geometry or, rather, the rocker arm geometry. The entire upper valve train is getting replaced, except the valves themselves. The valve springs have started rusting, and the engine also has dual valve springs which is way overkill for the cam and RPM we are …
(In case anyone wondered why there was a lapse in updates, it’s because of this little guy who arrived on January 28. It’s gotten a bit harder to find time to work on the engine since then, although it’s so close to the end I’m going to try hard to get it done.) Now that …
It’s finally time to close up the case. But first a little tidying up. There’s been a small amount of binding when turning the crankshaft with the Force One bearing mounted. Over perhaps 120 degrees, it was harder to turn than seemed normal. I had measured earlier that the prop hub had a runout of …
