Yeah… I know… that engine is missing its cylinders! That is very observant of you! The last post showed the ‘short block’ overhauled Lycoming O-360 engine – the base of the engine without cylinders. No, I did not forget about them. I had hoped to install new Superior Millenium cylinders. However; they are proving to… [Read More]
O-360 Going Back Together
After a lot of cleaning, measuring, inspecting, and fiddling; it was time for the new engine to start going back together. I should probably note that the measuring is related to wear limits established by Lycoming. Most everything in the engine has published limits – everything from bearing journal diameter to crankshaft out of round,… [Read More]
RV-4 Fuel System Changes
One of several areas that I wanted to clean up while down for the new engine was the fuel system inside the cockpit. Fuel flows from one of the wing tanks thru the fuselage and to the engine. To get there, it flows thru the fuel selector valve, thru an auxilary fuel pump, thru a… [Read More]
Sky-Tec Starter Overhaul
I had a Sky-Tec HT starter installed on my old engine and it has worked fine for a long time. I’ve pretty much ignored it. Keeping with the ‘while I’m at it’ theme, I decided to give it a thorough inspection before installing on the shiny new Lycoming O-360 (last mentioned here). The first thing?… [Read More]
Cleaning the O-360 Engine
Back to the overhaul of the Lycoming O-360 that is going on my RV-4. All of the ugly black shellac type stuff that had built up on the engine case had to come off. Some photos of that in this post. A few days in the solvent tank almost took care of that. It appears… [Read More]
A Firewall That Works
Continuing with this change from a Lycoming O-320 engine to a Lycoming O-360 on my RV-4… As previously discussed, the firewall had to be modified to make room for a rear mounted propellor governor. Not that I would likely install a constant speed prop right away, but I wanted to be able to do so… [Read More]
Engine Change Logic and Modifications
Decisions made – Lycoming O-360 Given my last post (here), the question becomes; why change engines if both of my options require an overhaul? Why not just stick with what I had and minimize the effort? Good question! There are a bunch of reasons behind my decision. Firstly, the O-360 with 180 hp is just… [Read More]
A Waiting Surprise
The time for the annual condition inspection for my trusty RV-4 had arrived. This is a very thorough inspection of every square inch of the airplane with some typical maintenance mixed in. I have a 160 hp Lycoming O-320 engine. Progressing thru my checklist, I arrived at the borescope inspection of the engine cylinders. That… [Read More]
Finishing the Kayak
youtu.be/5KHqubAQ7Hs
After the do-over (here), we were back on track to get this boat finished! Of course, lots of things seemed to get in the way but there was progress. Applying several coats of varnish was the next step. The fiberglass provides strength and waterproof-ness but needs protection from the sun (UV) – that is the… [Read More]
Making a Mess
Well… I goofed up and made a mess of the kayak. It seems that when I applied the final layer of fiberglass to the bottom and sides of the kayak, it was either too cold, too moist, or I messed up the epoxy mix – or all of the above. The epoxy was very slow… [Read More]
