I've had water pumps like that in the past. I was told they were for airplanes if the seal starts to leak the windshield won't get wet. I don't know if it's true or not but it sounds good to me :confused:

Doubtful, airplanes since the Jenny's are air cooled.
 
In 1928 there was the Pietenpol airplane that used a Model A engine mounted backwards in the air frame.

It was a homebuilt model and there still are a number of them flying today.

After Oct, 1929 the Depression made a cheap airplane popular.

I'm not a pilot so this is a completely novice question; Wouldn't the lack of straight ahead visibility on the Pietenpol airplane be a problem?
 
Visibility was a problem on the Pietenpol. Mostly the radiator was in the way. You had to get used to landing and taking off looking out the side of the plane.Once up and level in the air it was easier to see out the front. When Lindberg crossed the Atlantic in his Ryan airplane he had the same problem. Frank
 
Lindberg had same problem in the air ... so much so that he had a periscope installed in the plane to look over the front gas tank.

And from the book and movie he looked out the window alot also.

Another plane with front vision problem, on the ground, was the P51 Mustang with the long Merlin or Allison engine up front ...

As a kid I remember when the P51s landed at the airport next door that pilots always moved on the ground in a series of "S" turns so they could see in front.

Once the tail came up on takeoff and in the air it was easier to see in front.

I have run one of these for 25000 miles. Never leaked a drop. Mine has 3 impellers, 2 about half length and the other is gone. It doesn't so much pump the water as gently stir it on the way o the radiator.
 
There was a pietenpol built that had the engine in upside down with a lowered oil pan in an article in the Secrets magazine, probably had a sump pump for the oil like a radial engine.
 
If I remember correctly, there is a bushing in the rear, bearing in the front, with a spring and a thrust bearing to add tension to the mechanical seal. Mine was just a cast ring that runs on the front surface of the rear bushing. The whole inside of the housing is filled with chassis grease. Works great.

Where do some of you guys come-up with this stuff? Curtiss JN-4s (Jennys) have a water-cooled Curtiss OX-5 engine. If you even bother to take a quick peek, you can't mistake the radiator and shell, AND radiator cap in the picture. DD

In the 30s, the Aeronautics Branch of the Department of Commerce issued a call for bids to build a "$700 everyman's airplane". One of the entries was powered by a Plymouth 6, also mounted backward. Here's the story (including some Ford references) of the Plymocoupe, aka SE-AS-KA, and its sad end:

When your flying an airplane you don't look straight out the windshield like a car. I've ridden in a Pietenpol. Didn't even notice the radiator. Forward looks are usually towards the horizon so looking slightly to the side doesn't bother.

What does it look like under the cover?

Much like the regular Model A pump except in the space between the front bearing and the seal there is grease. Mine has a alemite fitting on the side to add more grease. The cover is not gasketed but there is no drain either.

The seal is spring loaded (spring around the shaft) and one assumes this is the later "hard" seal used on the Ford cars after Model A.

I have bought water pump variants at Amherst, NH for as little as $3. For a while I was collecting water pump variants.

Here are three pumps for sale BUY IT NOW for $19.95, one of these this JC Whitney Pump (not sure - makes sense.) Shipping is more than the cost of the pumps.

I think I paid under $20 with shipping for mine from Ebay but I have seen them for a little less than I paid - and for MUCH MUCH more.

Some people like to price so they have LOTS of listings, I think.

Ebay should charge "Rent" for the bandwidth this pricing practice uses up. That would encourage sellers to "stay real."
