Model T Engine

Recommended Posts

I'm building this for the TRAK forum but I thought I would post it here as well.  A big change from what I typically build but I'm really enjoying it.  I bought just the engine from an ebay parts seller so it will be just a display engine.   

Knowing very little about a Model T engine I did some research and found this very useful diagram.

The kit block had no bolt detail on the oil pan flange so I added some by cutting thin slices of hex rod.

I drilled some recesses into the transmission case cover (using a small ball bit turned in my fingers) to simulate the screws that hold it in place.

The lower cooling hose was cast into the side of the engine.  I removed it with a Dremel and various files then reshaped the front cylinder.

The engine comes the Fruit Wagon kit I think and has a total of (6) parts.  If this is going to be a display engine it needs more detail.  Here I have added the oil fill tube and cap, some simple fan belt pulleys and the makings of a starter crank.  The kit's upper cooling hose was just sticking out of the cylinder head.  I loped that off and made a new connection using a photo-etched header flange bonded to some flat sheet stock to provide additional thickness.

I would like to find those engine stands, where do you get that one?, looking forward to the progress report

It is included in Fujimi's Porsche 356 kit.  I bought a glue bomb kit and restored the stand.  AMT's '66 Nova has a similar stand.

Wouldn't be too difficult to scratch build.

The intake/carb/hot air pipe/exhaust manifold are cast as a single piece in the kit.  I wanted to separate them for further detailing. This required me cutting the tail off the exhaust manifold, I used some kit sprue to restore it.  While I was at it I added some additional material so that I could give the top line of the manifold a more correct shape.   I have a bit more work to do but you can see where it is going.

I was curious what the purpose of the “hot air pipe” was so I asked one of our resident mechanical gurus, Ace-Garageguy .  He explained the purpose was to draw heated air from around the exhaust manifold to eliminate/reduce “carburetor icing”, even provided a Wikipedia link that explained the condition.  I didn’t get a good picture but hopefully you can see how  I scalloped out the back side the hood of the hot air pipe to replicate the 1:1 part.

I separated the manifold and carb and made a flange from a small punch of sheet stock.  Drilled through all the parts and reinstalled them on a mounting pin.  A black was during final construction will tone down the colors and bring out some of the carb detail.

One small detail that is missing is the Magneto Post. It is a small protruding plug above the transmission inspection cover.  I'll fun out to the garage and get you a photo.  This is an engine that o wish was located under the hood of my 26 Runabout project! 

Eric, having a 1:1 in the garage you are obviously more knowledgeable about these engines than I. Would a generator and an electric starter be appropriate?  I believe the engine is from the '25 Ford Fruit Wagon kit. I have seen you tube videos of stand mounted T engines and many of them show a coil box, generator and an electric starter along with the hand crank.

Actually a better question is if a starter and generator would be inappropriate. It is fundamental to understand that the Model T Ford was in near constant evolution.  That being understood,  one could order a Model T with or without an electric starter and generator beginning in 1919, though today you will see many cars built prior to that year (including both of my 1915's) that have been retrofitted with electric starters and generators. This is not a task for the feint of heart as the engine and transmission have to come out and completely apart. In any case, your engine as it is now is a very authentic representation of an unequipped Ford engine. Adding a starter and generator along with the coil box would look good too but if this was my project I'd skip those items. Hope that long winded response helps.

Another part of the equation ought to be adding the two small petcocks to the flywheel housing, which were used to check the oil level, one directly below the other.   Adding the transmission pedals to the left side of the engine is another very visible and yet essential detail.  I really like where this model engine project is headed!
