    Spoke to Robert Baslee from Airdrome about my brake woes, and he is sending me a set of drum brakes to use instead of the band ones.

    I'll have to make custom backing plates, etc., but I've been down that road and have the templates for it.

    Hmmm, let's try this again.

    Prop hub on the crankshaft? Yep.



    Everything all lined up and the case put back together? Yep.



    After torquing the case nuts I stopped for the day. I was getting all scatter brained and started setting things down and forgetting where I put it and not finding things that were right in the open.

    Not a good way to be when I had the task of positioning piston rings and putting the pistons in the cylinders. Better to call it a day, drink some water, and get something to eat.

    I borrowed a bit from the instructions on the circle thingie that goes between the flat oil slinger and the prop hub. With it on the crankshaft I couldn't get a good view if the prop hub was fully seated or not when mounting it. It said that it could be split and the join rotated horizontally in the case once joined, so I did that.

    It's not a Force One, but it is a shrink fit hub from Great Plains.

    They really are great. They went above and beyond in answering my questions, even in areas not covered by my purchase of a prop hub, crankshaft, bearings, and gasket set.

    A huge plus for a guy like me is that they speak do-hickey.

    I need a pinion removal tool to back out and re-align the distributor gear...I was off a tooth when I put the darned thing back together. It's on its way and should be here Tuesday or Wednesday.

    Then it's a matter of putting the bolt into the prop hub (Dave has it to drill a hole for the cotter pin), putting the Diehl case and starter on the back of it, putting the spark plugs in, mounting it on the engine, filling it with oil, and seeing if she'll start and adjust the timing.

    Getting closer....

    Frank, good to see your engine coming back together...it has been quite the journey!

    I see one item that you might want to consider. With "aviation engines" it is standard practice to NOT have any pressure senders mounted to the engine block. The concern is engine vibration might crack the threaded portion of the sender due to the weight of the sender fatiguing the brass threaded portion. This concern is alleviated by mounting the sender on the firewall and connecting it to the engine with a flexible hose. You may never have a problem with the sender as installed, but if it cracks you may be going through this overhaul thing again. The flexible hose is good insurance and easily installed.

    Here are the fuel and oil pressure senders mounted on the firewall of my RV-6:

    I would also drill a small hole in the oil filler cap so it can be safety wired. More cheap insurance.

    Best wishes for a successful engine break-in!

    So engine is pretty much done. Just have to put on the valve covers, torque the spark plugs and hook them up, and mount the engine and prop.

    Just to show how my "bad luck/good luck" life works, there's a little spring that goes between the cam gear for the distributor and the distributor. Once everything is lined up as it should be, one simply drops it into a hole on the gear and puts the distributor on top of it.

    There is a cut in the side of the well where the distributor fits in to meet the gear, no doubt to allow oil in and out, and is about a third the way up from the cam gear. It is horizontal. The spring goes in vertically.

    I know that it is the perfect size - not one bit bigger or smaller than absolutely necessary for a zero tolerance fit - for the spring to fit through. The spring fell to its side and I used my little wooden skewer to pick it up and it simply vanished. Gone. Not popped out, just gone.

    The spring is in the engine. The tiny half inch long three eighths inch wide spring Is. In. The. Engine.

    Breathe.

    Flashlight down the hole. Can't see it. Start undoing the bolts to the plate where the mechanical fuel pump would go.

    Have my two Pros From Dover gently step in and volunteer, suggesting I sit in a chair and let them do it. Apparently I looked like I was about to rip the whole thing apart with my bare hands while producing a stream of profanities that would probably take the paint off the cars parked outside the hangar.

    Pump plate removed. Flashlight. No spring seen.

    Oil filler plate removed. Flashlight. Silence. More flashlight. "Hand me that magnet," Rusty says, and expertly removes it from the bottom of the engine.

    So fantastically terrible luck in having the spring go into the engine, but also wondrous good luck that it could be spotted and fished out.

    From there things went pretty quickly, and we moved the engine onto a stand over by the aircraft, hooking up various electrical things and turning it over to set the timing. It was off initially, but thanks to the flashy flash gun and an allen wrench, we soon got things right.

    I'd of mounted the engine on the plane, but it seems it's a bit bent. I don't know if I can true it up with a jury rigged press or have to make a new one, but I'm not too upset with that. It's just four pieces of square steel stock and some welds. Not to throw shade at Robert, but I can throw a bead of the same quality as is presented on the part from his how without much difficulty.
