I finally got my hands on that SOS transmission that Check Break alerted me to last September (original post linked below). After looking at it carefully, I'm guessing that it was originally purchased as a service parts replacement. I think this primarily because there are no stamped numbers whatsoever in the normal flat spot near the starting motor. That, and there is not a speck of blue paint anywhere on the case. Last fall it was suggested that maybe the case had been sandblasted, but that is not the case, it's simply all factory primer, along with a little rust.
It's the deluxe version with 2-speed PTO and the ground drive option. It also has the extra planetary in the back making it a 2000/3000 model trans.
The input shaft splines look pristine, making me wonder if it had ever even been installed in a tractor before. I'll know more once I pull it apart. Unfortunately, it was not well sealed at the steering box opening and rodents got inside and made a home amongst the planetary gears. It has been sitting on a pallet for at least 25 years.
As you can see from the images, the case was cast in December 1972 and the trans was assembled in July of 1973. If anyone has any idea as to what the BL7415 number means, I'd love to know what you think.
Sorry the pics are upside down. They were right side up when I loaded them.
