Odd overlap

Called Onan/Cummins for a water pump. My whole farm 19K generator needs one before the snow flies. Turns out they don't make them and there's no aftermarket. There's a guy in MN that will rebuild it for $200.

After lots of searching I found that a water pump from a 1942-53 Studebaker Champion Six was the same pump. Sure enough, it is the exact same unit. Thank you Internet.

How does that happen? It is an Onan built diesel. Was the guy that engineered that thing a Studebaker fanatic that had a water pump on the shelf to try? Seems like an odd marriage of parts to me.

Any other oddballs you know of?
 
Not overly oddball, but when we were racing stock cars, we would speed up the steering by putting Corvette steering gears into a standard Chevy manual steering box.

The day came when I built a Plymouth Duster stock car from Chrysler kit car blueprints for a buddy of mine. When the subject of speeding up the steering came up, I looked at the Mopar steering gearbox. The casting was entirely different from GM, but the pitman shaft looked awfully familiar. Checked it out and Corvette gears interchanged perfectly into the Mopar gear box.
 
Betcha that pump fits others as well - of only there was a backwards lookup. I know the wheel bearing on my Blazer fits several others.
 
Maybe not quite as odd, but the thermostat from
a Renault Le Car fits the Ford N series tractors.
 
Studebaker owned Onan for a period of time in the sixties. Don't know exact years or how long, but that would explain some ties with parts. Lee
 

Before Harley went with electronic igniton on the 74ci and 80ci shovelheads, points from a Chevy 216 6 cyl would intechange.
Nearly $20.00 from a Harley dealer, $3.00 from a parts store. This was back in the late 70's though.
 
a spark plug off a wd fits the bolt holed on a minnie grain drill bought a drill with plugs in i guess it was cheaper then a new bolt
 
Where I used to work they had a work boat with an Onan 6 cyl diesel, it had a mechanical fuel pump on it to feed the injecter pump, never did find one, used an electric and that didn't like diesel fuel so we rigged up a double set up, if the primary one took a crap the back up would automatically kick in. Remember that odd size wrench that came in the older sets?? I think it was 21/32, a couple of years back I was replacing tie rod ends on a WD Allis with a factory wide front and the tie rod clamps had that size of a nut on them, the only one I have ever run across in my entire life.
 
There has been some interconnection between companies. Ford trannies are now a GM design produced under license. At one GM foundry I was at over 30% of production was non GM. In europe, it is very common to share parts.
 
(quoted from post at 19:36:49 11/20/13) Now that was a Q U A L I T Y car.

The Renault? Oh Lord! Renaults were horrible! We used to think Fiats were bad and then a lady brought in some model of Renault. There's was almost nothing on that car that was working right and most of the reason was that it was little more than junk to start with. Add in a couple of NY winters and it was toast!
 
Looked at an 801 just traded in, checking it over before talkin' turkey. Found a spark plug in place of the fuel shut-off under the tank. Big storm going on while we were talking. Dealer scrambled to get it out before somebody tried to start tractor and managed to cause static spark to that plug/shutoff.
 
That is odd. My Aunt and Uncle had several and never had problems with them, all had put over a hundred thousand on them in all types of driving.
 
I have an old H-D tune up kit for a 70s XLH , XLCH hanging on the wall it has two number four plugs and points and condenser with a tiny tube of point cam lube. The AMF price tag is $8.95.. I think your H-D dealer was ripping you off. Maybe magneto points cost more but they came in a Fairbanks -Morse box with an AMF sticker.
