To the best of my understanding, the pump isn't driven by the cam gear, but directly by the end of the cam on the gear end. My assumption is that the cam end gets a slot milled in it, and a tabbed "puck" that engages the slot drives the pump directly...though I could be mistaken. The apparent offset between the crank centerline and what appears to be the oil pump looks to me as though this is the case. But again, without clearer photos, I could be mistaken. Just FYI, a slot in the old VW bug cams drives the oil pumps directly via a tab on one oil pump shaft that engages the slot. EDIT: The more I think about it, the less likely it seems that Horning would have disassembled the engines to mill slots in the end of all the cams. It's possible to mill a slot in the end of a Corvair cam while it's installed in the engine, especially as both the bellhousing and the timing cover would be removed to do the marine conversion, and the engines don't weigh too much to go on something like a Bridgeport mill...but I just don't know. But if the cam gear drives the pump. there's the problem of driving a small gear (for an oil pump) with a much larger gear (the cam gear), which will spin the smaller gear much faster. Oil pumps I'm familiar with rotate at or close to camshaft RPM. Horning was a competent and creative engineer, and it would be very interesting to see good photos of how he solved all these interrelated problems.

The short answer is that a cast alloy sump bolted to the original flywheel-end of the engine cases supplies an oil pump driven by the end of the cam. The new flywheel/ring gear, starter, fan, and oil filter adaptor are mounted on the original rear (pulley end) of the engine, on top. The new sump, main engine mount, steering gear, and power takeoff to the prop are on the bottom, the original "front" of the engine (the original flywheel end). The new oil pump housing is internally ported to direct oil into the same oil galleries in the case halves as the engine uses in horizontal applications, delivering oil to crank and cam bearings, lifters, and valve rockers just as in a standard installation. Used oil finds its way back to the sump via gravity, with a few deflectors and guides made specially for the vertical orientation. Mounting flat six engines vertically is not particularly unusual (as in several helicopter designs), but the marine installation including hydraulic steering and power transmission to the prop is unique. http://www.corvairs.org/Corvairsation/01May.pdf (there are some photos that are a little hard to decipher due to copying limitations, but with the other info on the web, you should be able to piece together a reasonable representation)

"Alive" sometimes doesn't seem to be all it's cracked up to be, depending on the level of pain.

Out anyone who has a dangerous, vicious, and probably rabid pet squirrel.

"Yours is mine, and mine is mine, and ours is mine" was the worldview of one of my exes.

Lot scarier to be in a convoy not protected by a few.

Life choices made when we're young and largely ignorant don't always look so good when looking back through the eyes of wisdom.

Beautiful beautiful beautiful. Loved those things from the first time I saw one light up, still do. EDIT: I'd built Monogram's M34 "Eager Beaver" 6X6 as a kid, and when I saw similar-looking trucks fitted out with armored beds, multiple .50s and even M134 chain guns salvaged from helos, I was like "C O O L !!!"

11:15 PM EST Nov. 6, 2024 Still intermittently hanging and pix won't load. Sometimes requires closing out and re-logging-on to get it to work at all. Yes, my caches are clear and I'm using the latest browser versions. No offense, but if somebody brought me a car to fix and I couldn't do any better than this after this much time, I'd seriously consider shooting it.

DING DING DING DING !!! WE HAVE A WINNER, FOLKS !!!

Bumper-car rides ain't what they used to was, because OMG OMG OMG they're DANGEROUS !!!!!!!!!!!!!!

Cute little trucks just might send the signal that you're not trying to compensate for anything else that's little.

Lotsa stuff. Pretty good day...so far.

Natural place for well-dessicated mice or rats in there too...and spiderwebs.

Looking really good, fantastic ref pix too. Somehow I missed it earlier, but I have a few of these to get to, and REALLY appreciate your posting this.

Me is happier and more hopeful this morning than me has been in some time.

Mirror mirror on the wall, who's that geezer looking back at me?

"Bible" is going to be a tough one to use without ruffling somebody's feathers.

Cool tool. I understand entirely. And it'll probably outlast 5 "modern" plastic ones with undersized motors and bearings.

Tomorrow at this time we'll know more.

I have some MREs from the late '60s or early '70s. Make offer. No lowballers. I know what I got !!!!!!!! https://mremountain.com/collections/vintage-mres-and-rations?view=boost-pfs-original
