***1909 (Early) Fan Assembly***

Post by VowellArt » Sat May 18, 2019 12:10 am

This is the fan assembly for the first 2499 Model T's built from 1908 to 1909. On the 2500th car they switched to the belt driven fan with the thermosyphen engine. What makes this one different is the 6 bladed fan riveted to fan shaft and it is the only Model T that came with a Water Pump.
The next assembly will be how this contraption meets up with the engine, because the front of this engine is totally different from what most of us know as the Model T block. If you've ever wondered what was in one of these like I have, this is it, simple, straight forward construction made entirely of brass (with the exception of the fan assembly).

And judging by their construction, I do believe they leak and need servicing a lot too.
Don't get me wrong, this was a fun one and thanks Royce Peterson for all your help! ;)

If anybody happens to know where I can find either Ford Factory Numbers or Part Numbers for the parts of this assembly, please let me know, thanks.
Fun never quits!

Martynn,

I always love your exploded diagrams showing how the parts fit together. Thank you so much for producing them!

I still haven't figured out how to add the photo/illustration and to be able to type below it. So I will add some comments here. I’m off to do some yard work before it heats up outside. I’ll try to come back and add why only the Factory Number and not the Part Number is available in Bruce’s listing for those parts after I get my chores done.

If someone has access to the 1909 Price List of Parts it should confirm that only the Factory Numbers and NOT the Part Numbers are shown for the Water Pump parts (as well as the other parts).

Again, thank you for the great illustrations of how they go together!

Respectfully submitted,

The Factory Numbers (which are the ones primarily used to request a Factory Drawing from the Benson Ford Research Center (the archives)) are shown in the illustration below:

Thanks Martyn

Really neat to see these in the drawings. I have had the privilege of holding one and being 'on the edges' of a rebuild. A very rare bit of kit.

What drives the fan and impeller?

For Martynn,

Recommend you consider extending the line down to the dotted illustration of factory number 437 "Pump Shaft" on the drawing. It is easy to miss that part unless you look at it closer. Or possibly doing a little cutaway on the fan so you can clearly see the shaft part? Again -- I love your illustrations.

For Richard,

The fan was attached to the same shaft Factory Number 437 that turned the water pump impeller and the fan. That shaft was driven by gear factory number 576; that was driven by the timing gear. The engine block on approximately the first 2500 engines had a different casting so a larger timing gear cover factory number 403 could be installed. See the photos below that will show how that fits together. But basically, the water pump was gear driven off the timing gear.

From the posting at: http://www.mtfca.com/discus/messages/11 ... 1267915959
Shows the early block with the timing cover installed but the water pump and fan removed:

For Adrian Whiteman -- thank you so much for the e-mail on how to be able to place the photos where I would like them to appear in the text!

Last January, I purchased a "water-pump" engined model T touring (Car number 2436), and in the four months I've owned the car, I estimate that I've driven it about five hundred miles. During this time, the pump has not leaked, nor has it required adjustment. I hope it continues to give excellent reliability.

Martynn, as always love what you are doing. I to wondered ,how all this went together. One small thing, could read from the radiator and turn your arrow around ? Arrow sorta looking like flow? Thanks and please keep doing what your doing. I see much of your art in the parts books now. Looking great!
