Hi All,
I am student teaching an agricultural mechanics class and as part of the class I am having the students rebuild a Ford 9N that was recently donated. As part of the project, we are tearing the engine apart and putting a rebuild kit into it as well as a 12 volt conversion kit.
My main question is, is there any way to identify the size of the sleeves before you have them out of the engine? I am aware these tractors could take two different sleeve sizes depending on the year, .040 and .090. This being a Ford 9N it came factory with .040 sleeves, which means they could have been upgraded to .090. The serial number is *9N97499* and the shop manual states that the star (*) designates the .040 pistons. Based on this, as well as it being a one owner only tractor with reportedly low power last time it was run, it is believed that the engine is an original .040 sleeve size engine. A engine kit with .040 sleeves was ordered based on this.
We just took the head off the engine today and one of the first things noticed was that the pistons are domed. From what I have found, some say this was a factory option, can anyone confirm? We are trying to determine if this engine has been rebuilt or not. The only thing that would suggest engine work is that the distributor has the "Reconditioned by Authorized Reconditioner" ribbon, though this could certainly have been done without any engine work being completed. The parts for the engined and electrical have already been ordered from Steiner due to the tight timeline needed and the time to process the order, so just trying to confirm before they are shipped so it can be changed if needed.
If anyone else has any other suggestions or advice please feel free to comment. This is my first time working on a Ford engine and it is a bit different than the Farmall engines I am used to.

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
