The new propshaft is finished now. I had to have the shaft straightened as it cam in with a bow; was replaced but the new one was bowed too. Anyway the clutch splines are cut as well s the keyways and the snap ring groove to contain the bearing.
The support bearing is 7/8" x 2" and the torque tube is 2.375 ID nominal so a sleeve is required.
The gearbox input shaft or constant mesh gear leaks down the keyways and drips into the torque tube. That oil can pass forward and end up in the clutch disk. See my previous post to prevent this. It didn't work. I have been advised to get a short length of bicycle inner tube to fit the gearbox input and to make a sleeve to Loctite onto the prop shaft to accept the forward end of the rubber tube. This looks like a great solution.
This photo shows the torque tube flange to the right with the propshaft sticking out to the left. The gear box is removed. When installing the gearbox I have the rubber sleeve rolled over on the input shaft. I slid the propshaft into the input shaft and rolled the rubber sleeve over onto the alum. piece to make the seal.
I will follow up with how this works out.
After 1500 miles of driving the prop shaft is working great. I do feel some heat coming from the support bearing (Chinese brand) so I may have to get a better one at some point.
