Model T Clutch Drum series - Version 2 T-725-B

[accuratemodelmaker]

To continue along with this series, here is the 2nd major series, the T-725-B.1 (first B version). This one has the 6 holes around perimeter, and the first to use the set-screw. The front thrust face is designed to be used in conjunction with T-769 (top hat) bronze bushing. The set-screw to thrust face is the noted .530" - .533". Nothing on parts drawing indicates whether this was used on Model TT.

Additionally, it has a slightly different design from the previous T-725-A, in that the set-screw and Woodruff key are aligned with the middle surface holes, instead of the outer lug. I was not able to get any info to confirm whether the "Ford" script is on the front side as previously reported many others here on the forum. If anyone has pictures of the script being there, please feel free to post them here and I will revise the parts drawings.

Next up in this series will be the T-725-B.2, which is when the top hat bushing was removed, and the Clutch drum was revised to work with the 3 washers. Some very interesting detail differences to be revealed.

Enjoy!
