Is there any difference in flywheels, from 1919 thru 1926.
Thanks in advance

At some point in that time period Ford changed over to a flywheel that had more machined surfaces than the earlier flywheels. The flywheels are 100% interchangeable. I suspect it was an effort to get more uniformity in the balance but . . . . just a guess. Someone else may know the exact timeframe of the changover, but I suspect it was around late 1925 with the introduction of the transmissions with the wide brake drum.

Sometime during 1926 or 1927 the flywheels were fully machined, not just the areas were the parts went. I have read in the past that these were better balanced from the get go then the early style and did not require as much tweaking later. While I only used a knife edges to balance mine, this seemed to be the case. The one I used needed very little to get balanced. Maybe not spun on a fancy machine, but got me to where I wanted to be.

I kinda keep my eyes open for the later machined flywheels. Right now I only have one and it's spoken for, by me. What I recall seeing, it was later closer to the end of production when Ford was starting to gear up for the Model A, but where I saw or read it do not recall.

The 1928 Model T Parts Book lists a 3269C for 1911 to 1919 (which did not have a starter or need a ring gear) and to replace it with 3269G and 3268, which is the starter ring gear.

The G suggests there were 7 flywheel variations, but all should be replaced with a starter ring gear type.

That might be because the transmission cover could be changed to one with a starter mounting hole.

All Model Ts could be purchased from 1919 through 1927 without the electric package, but the flywheel always came with the ring gear for an easy upgrade.

The generator upgrade did not exist before 1919 and all later engines had that feature with a blank off plate for the none-electric version.

Somewhere, a long time ago, I seem to remember reading a list of all of (or, maybe at least a lot of...) the many "improvements" that caused the '26 and '27's to be nicknamed "the new improved Ford". Maybe the additional machining done on the flywheels was one of those "improvements". (???)
