I have broken/bend parts in my gearbox cover and the lower crankcase. These parts are useful for the great functionning of the oil circuit?
I am sure there already a thread on this topic, but I don't find it.

Wonderful to see you posting Brice. You have a very rare, very special, set of parts here. You will need some special advice from one of the very few people with experience in what you have.
I will start another thread and link to here with a title to hopefully catch their attention.

I have been wondering about your wonderful project. I am very pleased to see that you are working on it.

Know next to nothing about the early crank case pan, other than it is one piece

But that little strip riveted to the inside parallel with the center, seems to be original design as you can see it in the Aug 1, 1909 Model T Parts and Price list book.

The crankcase sure looks real good condition to me.

Is that a early pan with a door cut in the bottom that someone did to be able to service the rods?

Jim

No door, that solder joint you see is for retaining the 'back splash' dam that is soldered across the deep sump. Ford though it necessary to retain oil in the pan dips.

There is an early one-piece pan here in Northern Michigan. I have seen it in person, but did not touch it to move it around for photographs. I can supply the contact info for anyone who wishes to get in touch with the shop the pan was seen in, for more information. -Ed

This is the following of my project :

How these parts have to be to be sure to get a great oil system ?

Ed : Sorry, I did not understand you message at my first reading. Yes It could be interesting to see the other side of the part.

But on the later model T it is not the same ? These parts are useful for the oil "pressure"? How they are made?

Brice, I have contacted the shop that has the early pan. He will try to get pictures Wednesday.

Thank you!
